Hiking Half Dome in Yosemite, A Step-by-Step Guide

Julie United States 42 Comments

The hike to Half Dome is one of Yosemite’s most challenging and most memorable hikes. On this hike you get to walk on some of Yosemite’s most popular hiking trails, view the Vernal and Nevada waterfalls, and walk through shady forests of Sequoia trees. But the best part of the trail is the final climb on the Half Dome cables and your reward from the top, one of the best views of all of Yosemite.

We hiked Half Dome as a family in July 2017. At the time we did this hike, Kara was 12 and Tyler was 14.

If you are planning to hike to Half Dome, here is what to expect, from start to finish.

What is Half Dome?

Half Dome is one of Yosemite’s most recognizable landmarks. The top of this granite dome sits 4,800 feet off of the valley floor at a total elevation of 8,844 feet (2,695 meters).

Half Dome Yosemite

There are several ways to get to the top of Half Dome. Most people get here by hiking the 17-mile round trip route from the valley floor and taking the cable route to the top. Rock climbers scale the vertical face of Half Dome to the summit.

Half Dome Permits

You must have a permit in order to climb the subdome and the Half Dome cables. Permits are awarded in a preseason lottery for the entire summer hiking season.

A maximum of 300 permits are awarded per day, with 225 for day hikers and 75 for backpackers.

As the Half Dome hike grows in popularity, the chances for being one of the lucky lottery winners decreases. To learn more about the permit process and how to increase your chances of winning the lottery, read our post.

You can also get more information on the National Park Service website.

Hiking Half Dome

This post covers the one-day hiking route we took to Half Dome. We hiked up the Mist Trail and down the Muir Trail, one of the most popular hiking routes to Half Dome.

Facts About the Half Dome Hike

Distance: 17 miles round trip
Elevation Gain: 5,457 Feet
Difficulty: Extremely strenuous
Length of Time: 10 – 14 hours
Permits: You must have a permit to climb the subdome and the Half Dome cables.
When to go: The cables are up (conditions permitting) from Memorial Day through Columbus Day. It is possible to climb Half Dome when the cables are down, but that is beyond the scope of this post.

Please note: If you read other blogs and information provided by the National Park Service website, you will see the distance for this hike ranging from 14 to 18 miles. Choosing the Muir over the Mist Trail can impact these variations. We hike with a Garmin GPS and use the stats it outputs for these hiking posts.

The Route to Half Dome

The photo below was taken from Washburn Point, very close to Glacier Point. In this photo you can see most of the hiking route to Half Dome (the yellow dots). The trail starts at the valley floor (not visible in this photo) and climbs up next to Vernal Fall and Nevada Fall. It passes behind the Liberty Cap, through Sequoia forests, and then up the far side of the subdome and Half Dome.

Half Dome Hiking Route

The Trailhead

The hike starts on the Mist Trail. The closest parking is the Yosemite Valley Trailhead Parking, located just past the Half Dome Village. From this parking lot, it is a half-mile walk down a service road to the Happy Isles Bridge and the start of the hike.

You should consider starting the hike as early as possible, sunrise or even earlier. If you are staying in Yosemite and will be using the shuttle bus for transportation, they do not start running until 7 am.

Our day started very early. We stayed in Mariposa, located one hour west of Yosemite. At 4 am we rolled out of bed and at 6 am we started the hike.

Tyler and Kara

High Sierra Loop Trail

Vernal Falls

The first part of the Mist Trail is a paved, asphalt trail that constantly gains elevation. It is steep at times. From the trailhead to the top of Vernal Falls, it is 1.5 miles (2.4 km).

Just past the Vernal Fall footbridge, only 20 – 30 minutes into the day, is a water fountain. This is your last chance for drinking water on the hike, unless you plan on purifying water from the Merced River. This is also your last chance for flush toilets.

Last Water

Past the footbridge, the trail climbs steeply and steadily to Vernal Fall. And this is where you see how the Mist Trail earns its name. Long, slippery staircases wind uphill along the river and the falls. During this part of the hike, you may get drenched by the mist. In July, this mist is refreshing and it kept us pleasantly cool. During cooler months, you may want to bring a poncho with you to keep you dry.

Vernal Falls



Once at the top of the falls, there’s a spectacular viewpoint and a great place for a photo op.

Top of the Falls

Nevada Fall

The climbing continues up to Nevada Fall. The trail winds through shady forests and more staircases constructed out of rock and boulders. From Vernal Fall to Nevada Fall you will hike 2 miles (3 km).

Forest Trail

Hiking with Kids

The trail splits near the top of Nevada Fall. Go left to continue onto Half Dome. You can go right, hiking 0.2 miles (0ne way) for an optional detour to the top of Nevada Fall. However, if you choose to hike down the Muir Trail at the end of this hike, you will pass this same viewpoint.

Trail Split

We chose to walk the short distance to Nevada Fall. It was a beautiful morning with hardly anyone on the trail, so we wanted to see the falls before the crowds arrived.

Nevada Falls Bridge

Liberty Cap

The Trail to the Subdome

After Nevada Fall, the trail levels out for a little bit. Enjoy this…soon the climbing starts again.

Flat Trail

After passing Little Yosemite Valley, the trail climbs through a forest of Sequoia trees. It’s not a hard climb, just a constant, steady uphill walk. Occasionally, through the trees, you will get a glimpse of Half Dome. If you look closely, you may even be able to see climbers on the cables.


There it is

The Subdome

Climbing up the subdome is difficult. We named this part of the hike the Ass-Kicker Stairs because that’s exactly what they are.

By now, we were at 8,000+ feet. And we were tired. We just hiked for three and a half hours uphill.

These steps seem huge and by now it didn’t take much to get us out of breath. We’d walk up a short ways, take a brief rest, and then continue on again.

It’s slow-going, but the view that awaits you is so awesome.

Climbing Sub Dome

Sub Dome

From the top of the subdome, you get your first close up view of the Half Dome cables. Now the real fun begins!

Half Dome Cables

The Half Dome Cables

It took us 4 hours to hike from the start of the Mist Trail to the top of the subdome. Even with kids, this is a very fast pace. We are not “stop and smell the roses” kind of hikers. When we hear that it takes 10 hours to finish a hike, we see that as a time to beat. That’s just how we are.

Our climb up was quick since there were very few people in front of us. I knew to expect a steep incline and slick surfaces, but even so, the difficulty of this climb took me a little by surprise.

This climb is hard! Don’t underestimate it.

Climbing the Cables

The granite surface has been worn smooth by the shoes of the thousands of people before us. The climb is so steep that we pulled ourselves up more with our upper body strength than by walking up with our feet.


It took us roughly 20 minutes to climb the 400 feet up the Half Dome cables. With very few people in front of us, we only had to take several short breaks as other hikers climbed down past us.

Tyler Rivenbark

It’s a relief to finally reach the top. We made it!! Now we could take in the view and enjoy our accomplishment.

For more information on climbing the Half Dome Cables, read our post filled with photos and what to expect on the cables.

On Top of Half Dome

Initially, we planned on a longer stay here than what we actually did. But rain clouds were in the area, and now knowing just how steep and slippery Half Dome is, we did not want to be on those cables if it started raining. After a few photos we headed back down the cables.

The Visor


Climbing Down the Half Dome Cables

During our brief rest on top of Half Dome, many more people arrived at the cables. It took longer going down since now we had to wait to leapfrog around other climbers. But that gave us more time to enjoy the view and take photos. For us, being on the cables was thrilling and we loved every minute of it.

Edge of the dome

Now that there were more people on the cables, our descent took a total of 45 minutes. By the time we were on the subdome, it did rain, just a little bit, just enough to justify our decision to descend early.

Hiking Back to Yosemite Valley

To get back to the Yosemite Valley, you must retrace your steps back down the trail towards the Mist Trail.

Yosemite Hiking

Final View

Muir Trail or Mist Trail?

Once you are at Nevada Fall you have a decision to make. You can hike down the Mist Trail or the Muir Trail.

If you continue down the Mist Trail, you will completely retrace your steps to the valley floor, descending on those steep, wet stairs next to Vernal Fall. Also, the trail will now be filled with many more hikers, now that it is early or late afternoon.

Or, you can veer off onto the Muir Trail. The Muir Trail adds an extra 1.5 miles to the hike, but it is less steep than the Mist Trail. Plus, the Muir Trail gives you a great view of the back of Half Dome, as well as the Nevada Fall. If you want to see a different view of Yosemite and don’t mind a longer but less steep descent, consider the Muir Trail.


We hiked down the Muir Trail. The first mile is spectacular. We loved the views of Half Dome, Nevada Fall, Liberty Cap, and down to Yosemite Valley. Because of these views, we were glad we chose the Muir Trail. But it does add extra distance to the hike, and most of the trail is long, steady switchbacks for four miles, all of the way until you get back to the Vernal Fall footbridge. Most of the Muir Trail is monotonous, and if you are like us, by this point, you just want to be done. We practically jogged down the trail because we wanted to get done quicker.

On the Muir Trail

Muir Trail

By now, it was mid-afternoon and temperatures in Yosemite were in the 90’s.

By the time we reached the end of the trail, once again back at the Happy Isles Bridge, we had hiked for 8 hours and 50 minutes, including time for stops. Somehow, Kara managed to hike the entire 17 miles on her very young legs, a major accomplishment. Tyler did even better, carrying extra weight on the trail and setting our fast pace.


Hiking Half Dome is an accomplishment to be proud of at any age. And once you do this hike, you will never look at Half Dome the same way again.

Want to see more? Check out our Half Dome video:

Should you Hike Half Dome?

Do not underestimate this hike! Over twenty people have died hiking Half Dome (either from falling off the cables, having a heart attack, being struck by lightning, or from failed base jumps).

If you have a fear of heights, you should not do this hike. The trail up Half Dome is very steep and very slippery. This is not the place to confront your fears.

You must have a very good level of physical fitness. You will be climbing (and then descending) 5,500 feet. Most of this climb comes before the subdome. If you are fatigued by the time you get to this point, it only makes the hike more dangerous. Once you are on the cables, it is a very strenuous climb to the top. You will need to be able to pull your body up using your upper body strength. This is not to be underestimated. If you do not think you are fit enough or have enough upper body strength, go no farther than the subdome. And just remember, once on top of Half Dome, you still have at least four more hours of hiking to get back to Yosemite Valley.

Young children should not do this hike. Again, this hike is dangerous and not a place to bring young kids. In our opinion, the youngest age we would recommend is 12 years old, and only if they have lots of hiking experience.

If you are traveling with kids, it is safe for them to hike to the subdome. They can wait here with an adult if someone in your group wants to hike up the Half Dome cables.

If rain clouds are in the area, do not climb the cables. Half Dome is not a place you want to be in with rain, wind, or lightning. People have died on Half Dome from being struck by lightning.

For more information on the climb, watch this video on the National Park Service website.

What to Bring on the Hike

Hiking Shoes. You need hiking shoes or boots for this hike. No tennis shoes and no running shoes. You need to wear shoes with good traction to minimize slipping while climbing the cables.

Water. The National Park Service recommends 4 liters of water per person for this hike.

Gloves. Gloves are a necessity for climbing and descending the cables to protect your hands.

Your Half Dome permit. Make sure you have this packed in your backpack. You will also need to bring a government issued ID that matches your name on your permit.

Sunscreen. There is shade on the trail, but the cables and Half Dome are totally exposed and most likely you will be here midday.

Harness and Clips.  This is the best way to stay safe while climbing and descending the cables. If you plan to do this, you will need a harness, carabiners, and a Y-shaped lanyard.

Hiking poles (optional). As I have gotten older, I am having more problems with my knees, especially on hikes with a large descent at the end. Hiking poles are my new favorite hiking gadget and I highly recommend them. They take about 30% of the weight off of your legs as you descend, easing knee pain and other symptoms. I use Black Diamond Distance Z poles and love them. They easily collapse down to fit in your luggage and hiking backpack, plus they are extremely lightweight. The poles come in several sizes, so make sure you pick the right length based on your height.

Alternatives to the Mist and Muir Trails

There are several other options for reaching Half Dome, other than taking the Mist and Muir Trails.

From Glacier Point: 20 miles round trip

From Tenaya Lake: 23 miles round trip

You can break up this hike up into two or three days by camping overnight in Little Yosemite Campground. On day one, hike the Mist Trail to Little Yosemite Campground (4.3 miles), on day two hike 7 miles round trip to Half Dome, and on day 3 hike back to the Yosemite Valley via the Muir or Mist trails.

  1. Hi,

    Great blog. Thank you for taking the time to write. Your passion for hiking really is amazing.
    My daughter and I just received our permit for Sept. 10. Somewhat concerned about the daylight hours also trying to secure lodging has been a challenge. We would like to stay in the village or close. Any thoughts on the comfort of the canvas tents. These seem to be the only option as well as any other thoughts.

    Grateful in Wisconsin,

    1. Post

      We had a bit of a hard time finding accommodation, too. I don’t know much about the canvas tents. We decided to stay in Mariposa, at the Best Western. It was a longer drive to get to Yosemite (I think it took 45 minutes to drive to Yosemite), but more comfortable than sleeping in tents (and much cheaper than the lodging inside of Yosemite). If the Best Western (or another hotel) in Mariposa is available, you have options, so it might be worth looking into. On the day we hiked Half Dome, we got up at 4 am and drove right to the park. Bring headlamps just in case it gets dark on your hike back to the valley. It’s not ideal, staying so far from the park, but it worked OK in our situation. Good luck! Cheers, Julie

  2. Where did you stay in Mariposa? I was just awarded via half dome lottery for a Thursday in July and would like to drive up Wednesday night and get a good night’s rest before beginning. Never done a hike quite like this. What trails in SoCal would you recommend to prepare for a hike of this height and duration?

    1. Post

      Congrats!! That’s awesome you got a permit. We stayed at the Best Western in Mariposa. I don’t know any specific SoCal trails to recommend, but I would recommend doing one or two hikes of 12 to 15 miles with a lot of elevation gain (at least 3000 feet). Getting on a stairmaster would also help your training. Good luck…it’s an amazing experience! Cheers, Julie

  3. Great article, Julie!! So helpful! Question for you: can someone without a permit hike with me all the way up to the cables (then wait while I do the cables)? Or is the permit for the entire hike? Thanks so much!

    1. Post

      Technically, you need a permit to hike the sub-dome and the cables. The sub-dome is the last major climb right before the cables. This is where you first start to hike up the giant chunk of granite that “is” Half Dome. The cables are really just the last little bit to get you up on top of Half Dome. Rangers can check permits for the Half Dome cables at the base of the sub-dome. So, even if you don’t plan to hike the cables, if you get caught on the sub-dome without a permit, you could be fined (and it’s a big fine). So it’s probably not worth taking the risk, in my opinion. Your friend could wait at the base of the sub-dome, but he/she could end up waiting 2+ hours, depending on your hiking speed and crowds on the cables. But yes, your friend can hike to the base of the sub-dome without getting a fine. There is a sign that marks the point where you need a permit. It wouldn’t hurt to confirm this with a call or an email to the National Park Service in Yosemite. Cheers, Julie

  4. Hi, I’m from Melbourne, Australia do rockclimbing and hiking here but am wondering about the altitude differential and fitness- Australia is the lowest continent above sea level so will this hike be more difficult? Would you suggest acclimatising somewhere like Colorado first?
    I plan to travel over solo for this, and am looking to do the mist trail up the dome, returning down JM as you did.
    Any suggestions are welcome

    1. Post

      The elevation difference shouldn’t be an issue hiking Half Dome. The ending elevation is 8800 feet (2700 meters), not high enough to cause altitude sickness. We live on the east coast of the US which is just a few hundred feet about sea level (we flew out and did this right after a few days in San Francisco, also at a very low elevation). You will notice the elevation change as you hike up Half Dome…about halfway through the hike we began to feel more breathless, but it wasn’t too bad. As long as you have a high level of physical fitness you should be able to handle the distance and the elevation gain. Have fun!! Cheers, Julie

  5. Love your website. You show many inspiring places to go and provide ideas to help us enjoy our lives. Could you rank by difficulty the top 5 day hikes that you have done THANK YOU…..I am curious to see how the half dome hike ranks. I have done a fair bit of hiking in my younger days, but have not done a lot of mountain hiking for a while. My concern is the distance….not afraid of heights….but at 50 years of age, my pace has probably slowed, so am concerned about finishing the hike before the sun sets. Keep up the great posts!

    1. Post

      Hello Travis. We have a post that you would love: 10 Best Day Hikes in the World, where we rank our top 10 favorite day hikes. As for difficulty, with #1 being the most difficult, here is our order (and this is everything we’ve done, not necessarily our very favorites, although they’re all good): #1 Half Dome, #2 West Rim Trail in Zion, #3 Koscielec in the Polish Tatras, #4 Trolltunga (if you do the entire hike and don’t start at the upper parking lot), # 5 Tongariro Alpine Crossing in New Zealand, and other tough ones are the Kintail Saddle in Scotland, Rysy from the Slovakian Tatras, and Romsdalseggen Ridge in Norway. This list will change soon, because Tim and I will be hiking the Narrows top-down in Zion in one month (16 mile hike) and going Rim to Rim in the Grand Canyon later this year. 🙂

      Half Dome is the toughest day hike we have done. You have the option to camp in campground on the trail, breaking the hike up into two days, if you want. It’s a long, exhausting day, but so worth it!! Plan your trip for May or June, if you can, so you have the most daylight, and keep your fingers crossed to get a permit. Happy hiking!

      Cheers, Julie

      1. Thank you for your reply and insight…great stuff…especially appreciate the tips on the Half Dome lottery. Earthtrekkers.com is one of my favorite travel websites, and I continually look forward to reading more about your travels….also, I’ve been inspired to travel more….am starting to train for the half dome. Also, looking to try Canadian Mountain Holidays Heli Hiking in Alberta. You might want to take a look.

        1. Post

          Ooohh…that sounds cool. Thanks for the tip! The Canadian Rockies are still on our bucket list and heli hiking would really make it a great adventure. Have fun training for Half Dome and good luck getting a permit! We are planning to hike the Zion Narrows in October and Grand Canyon Rim-to-Rim this December so we have some more epic hiking ideas coming your way. Thanks for commenting! Cheers, Julie

    2. I need to know where I can obtain a permit? What days are the best to go? What is the closest lodging to the start of the hike?

      Thank you

  6. Hi, I just found your section on half dome. Do you have a recommendation for an alternative trip that is strenous and scenic, but not quite as dangerous as the Half Dome Trail? Thanks again for this great narrative and photos of your experiences.

    1. Post

      The hike to the top of Yosemite Falls is strenuous and from the top you have a great view over Yosemite. Clouds Rest is a long day and a strenuous hike but there tends to be less people on the trail. We have not done this yet so I don’t know what the view is like from personal experience, but a friend of ours who is a frequent visitor to Yosemite loves this hike (and Half Dome). Cheers, Julie

  7. Hi Julie,

    Thanks so much for writing about your family’s experience. I just hiked the Half-Dome this past week and it was truly amazing but also very exhausting! Your post really helped me prepare for the experience and for that I am forever grateful!


    1. Post
  8. Hello,

    Thank you so much for this amazing detailed blog! We just climbed the Half Dome yesterday and your blog was super helpful for us in planning our trip 🙂

    We both thought that the “Ass-kicker” stairs was aptly named and was the most difficult part of the hike.

    1. Post

      You are welcome, Antriksh. You’d think that the cables would be the hardest part…but those stairs really are difficult. I’m glad you had a good trip! Cheers, Julie
