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.

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.

Half Dome Cables

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.

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 Half Dome

Final View of Half Dome

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 Half Dome

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.

Finished Half Dome

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.

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. We did not use a harness and clips on the cables, but if we did it again, we would.

Hiking poles (optional). Hiking poles 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. Just did this hike on 11/9/19. I have backpacked before but not with all this elevation gain and YES it’s a tiring hike any way you slice it!

    We had daytime highs of 65-70 degree and full sun. Oct/Nov can be great hiking weather. We hiked only to subdome. Cables were down of course, but dozens were still summiting. Most had climbing gear to affix themselves to the cables – one cable was up and the other down. There were a few who wore nothing but gloves, including a 20-something European man. No thanks on that! Just “let the heavy cable hold you to the wall”, said a 50-something American, who had just had a simple harness and caribiner, while I didn’t think would arrest his fall but would at least keep him from sliding off laterally to his death.

      Wow, thanks for your hiking report! I had no idea that hiking up Half Dome was so popular after the cables are down. Cheers, Julie

  2. Hi Julie! Almost 2 years ago, this blog post inspired me and my husband to hike Half Dome for ourselves. (Your photos of the Mist Trail was what actually hooked my husband!) Sunday, we arrived home from our trip. This hike was absolutely gorgeous and climbing the cables has got to be the most adventurous thing I’ve ever done. It’s an incredibly special memory for us both! I just wanted to thank you for sharing your family’s adventures and helping others plan their own.

    God bless, Carissa

      Hello Carissa. Thank you so much for sharing your experience! I’m glad that we could inspire you and help you have this adventure. Now it’s time to start dreaming and planning your next big adventure. 🙂 Happy hiking! Cheers, Julie

  3. Oh my, I just discovered the Half Dome while internet browsing and did some google searches. You and your family and those kids to make that trip up the half dome is amazing, and anyone for that matter. It terrifies me just looking at the pics and videos online. I love your family’s energy!!!!!!!

  4. I am planning to hike the Half Dome end of July or beginning of August ’19. I will request you to please inform if I may be able to grab a walk-in first-come-first based entry lottery. Also, will this trip require a night-camping? I have hiked several times to Vernal Falls and Nevada Falls in the past.

    1. Post

      It depends on how many other people enter the lottery for the day that you would like to hike Half Dome. We have a post on how to get the permit for Half Dome, plus you can learn more about the daily lottery on the national park website. Cheers, Julie

  5. Thank you for such a descriptive guide. The pics really helped and they are beautiful. Thanks for taking the time to take and post. I’m hiking HD in two weeks. Can’t wait. I’m 55 yrs old an d in the best shape of my life. We’ve been training for 10 weeks., Including, weights, cardio, long,/steep hikes. Thanks again for your guidance. Kristine

  6. My fiance and I just booked our honeymoon to Yosemite and I am SO GLAD I found this blog post on Pinterest! I’ll be 30 and he is 34 and I say if we don’t make this hike now, we never will! Thank you for sharing this, I’m not in terrible shape but I’m also not in GREAT shape. I think I should start adding some extra cardio training in my life! Do you suggest starting as early as possible? Like sunrise? We’ll be going end of September so the heat may not be as bad as the summer months.

    1. Post

      Hello Courtney, I’m glad you found us too. 🙂 Yes, I recommend starting as early as possible, to beat the heat and the crowds. You’re right, you won’t have hot conditions, but it could still get warm midday. But it’s more important to get there early, preferably before 10 am, because that seems to be when the cables start getting busy. It’s more enjoyable and safer to be on the cables with just a few people. Have a very happy honeymoon and I hope you have a blast in Yosemite. Cheers, Julie

  7. Hi there! Y’all were a big help in my journey up Half Dome (July 4th 2019). What an amazing day it was.

    I just wanted to share my personal thoughts on the hike and cables experience. The hike is TOUGH! I went solo, but met many friendly hikers along the trail. I started at 5am from the trailhead parking lot and wore a headlamp for the first 30-45mins of the hike. I found it difficult around Nevada Falls and some sections of the never-ending forest. I would HIGHLY recommend hiking poles or if you’re lucky enough to find a nice hiking stick. It will definitely help out during your trek up.

    My thoughts on the cables – We got to the base of the cables around 9am and it took about 15-20mins and we only passed about 4 people coming down. I am somewhat scared of heights, but I can deal with it. When you look at the cables they are intimidating and videos and photos do not do justice. I wore max grip gloves from Lowes and they were perfect. I hear that regular work gloves without grip are not the best, but will work for the cables. Having a grippy glove will be the safer choice. The cables are A TON of upper-body strength so make sure you work out those muscles prior to your trek.

    I thought about bringing a via ferrata harness so I could be extra safe, but I am happy I didn’t. I don’t see it being safer since you are clipping in and out every 10 feet and taking one of your hands off the cables to do so. The wooden planks are the biggest blessing since you can rest and catch your breath before you climb to the next one.

    After you have made it to the top and enjoyed the amazing views of Yosemite you have to make your way down the cables. In my mind the plan was to always go backwards, but the easiest way is going forward down the cables. Yes, it sounds crazy, but you can see what you are doing first hand and where your feet need to go. Due to discontinuity in the granite and slick spots from hikers wearing down the granite it is by far the best choice. It almost felt like I was rappelling down to each plank by letting out the grip on my glove (slow and easy). Of course when we came down more folks were coming up, but that meant we got to enjoy the view from the cables. Communication is the biggest key on the cables since there are no rules.

    Again, much appreciate your guide to Half Dome it certainly prepped me before my journey and was very useful!

      Hello Scott. Thanks for you awesome trip report. It’s always nice to hear from other hikers, their experiences, and tips and tricks to help others out. That’s great that you got an early start…it’s nice to get up and down the cables before big groups of people arrive. I’m so glad that we could help you out and happy hiking! Cheers, Julie

  8. Hey there.

    Great blog. Much appreciated on all the details. I have a permit to hike half dome in September.

    On one of your posts you mentioned that you would wear a harness up the cables as a safety measure for next go- around. A couple questions: 1) Did you see others using harnesses. Meaning,,is it fairly common? And 2) What did you mean by a “y shaped lanyard”? I’m not a climber, so I just want to make sure I understand.

    Any thoughts are appreciated.

    1. Post

      Yes, we saw several people wearing harnesses on Half Dome. I think it is becoming a more popular thing to do now and it’s a nice safety precaution. The harness is basically the belt and leg straps that you tighten to your body so it can’t come off. The y-shaped lanyard is a lanyard that on one end attaches to your harness. The other end has clips. You attach these clips to the cable on Half Dome. Every time you hit a post (the attachment point for the cable to Half Dome), you undo one clip and reattach it to the other side. And then you do the same thing for the second clip. It adds a small amount of extra time to clip and unclip over and over but this is how you stay safe, since you are now always attached to the cable. Look into renting or buying this set up in your home town before you go. I don’t have any recommendations on where you can rent it near Yosemite. If you go to an outdoor equipment store or rock climbing center, they should know exactly what to get you. Have fun! Cheers, Julie
