In Haleakala National Park, you can combine two very unique trails into one big day hike. The Sliding Sands Trail, which is one of the most popular trails in the park, starts on the rim of Haleakala and ends on the crater floor. To finish the hike, you can retrace your steps back up the Sliding Sands Trail, or, for a more interesting experience, cross the crater floor and hike back up to the rim on the Halemau’u Trail.

Called the Sliding Sands Loop, the combination of the Sliding Sands Trail with the Halemau’au Trail forms an 11-mile point-to-point hike that provides ever changing views of the Haleakala crater. It’s a long hike, and can be logistically challenging, but it’s worth it. We loved this hike and it was one of our favorite experiences in Hawaii (it’s also one of our favorite hikes in the US National Parks!).

On our recent visit to Haleakala National Park, we hiked this trail in both directions, so we have lots of great information to share with you.

In this guide to the Sliding Sands Loop, we cover what to expect on the trail, transportation logistics, tips to have the best experience, and alternatives to hiking point-to-point across the Haleakala crater.

Below are the stats for hiking the Halemau’u Trail first and ending with the Sliding Sands Trail.

Start: Halemau’u Trailhead (elevation: 8,000 feet)
Finish: Sliding Sands Trailhead, next to the Visitor Center Parking Lot (elevation: 9,850 feet)
Distance: 11.2 miles
Total Ascent: 3,600 feet
Difficulty: Strenuous
Length of Time: 5 to 7 hours

Which Way Should You Go?

The hiking distance and the views are identical on both routes. However, it’s MUCH easier to start on the Sliding Sands Trail and end with the Halemau’u Trail.

The Halemau’u Trailhead sits almost 2,000 feet lower than the Sliding Sands Trailhead, so if you start on the Sliding Sands Trail, you will have much less elevation to tackle. We’re talking a total of 1,800 less feet to climb if you start on the Sliding Sands Trail.

Please practice the seven principles of Leave No Trace: plan ahead, stay on the trail, pack out what you bring to the hiking trail, properly dispose of waste, leave areas as you found them, minimize campfire impacts, be considerate of other hikers, and do not approach or feed wildlife.

Hiking the Sliding Sands Loop

Here is the trail description and lots of photos, starting with the Sliding Sands Trail and ending with the Halemau’u Trail.

Sliding Sands Trailhead

Park in the visitor center parking lot. There are restrooms here and if you want to get trail updates, you can speak to one of the park rangers at the visitor center.

The trailhead is located on Haleakala Highway (Route 378), right next to the entrance into the parking lot. Just look for this sign (below). The Sliding Sands Trail is also called the Keonehe’ehe’e Trail.

The first part of the trail heads parallel to Haleakala Highway for a short distance. Once you walk around the bend, you have your first view of the Haleakala crater.

How to Hike Sliding Sands

The Sliding Sands Trail is mostly downhill, so you can make good time here, unless you are like us, stopping over and over again for photos.

This is such a unique hike. As you hike into the crater, you slowly descend from the rim through a landscape that looks as if you are walking on Mars. Off in the distance are cinder cones and a dark, almost barren volcanic landscape.

Haleakala Crater

The first part of the trail makes a few giant switchbacks as it descends into the crater. The trail is gravelly with a few rocks here and there, and it’s pretty quick moving at this point.

Sliding Sands Trail View

At roughly the 2 mile point, the trail levels out, just for a little bit, and gets a little rockier. There is also more plant life here.

Keep an eye out for silverswords. These small, silvery spiky balls are endangered plants that are only found on Haleakala on Maui and Mauna Kea and Mauna Loa on Hawaii. Silverswords can live up to 90 years but they only bloom once. If you get to see one, you are extremely lucky!

Into the Crater

IMPORTANT! Stay on the hiking trail at all times. Even though the crater looks like a barren wasteland, it is a fragile ecosystem. Stay on the trail, limit hiking groups to 12 or less, and practice the principles of Leave No Trace.

Crossing the Haleakala Crater

After one more stretch of switchbacks, and roughly 4 miles into the hike, you will arrive at the first trail junction. This is marked by a trail sign. Go left to continue to the Halemau’u Trail.

Trail Split

This spur trail travels through some the darkest, sandiest terrain. You are now crossing the Haleakala crater floor. It can be slow going for the next 2 miles, as hiking through this deep, black sand is slow and tiring.

Across the Crater

Next comes the hike up the side of the Halali’i cinder cone, which doesn’t look too bad in photos but is deceptively challenging since you are hiking up a sandy trail. But from the top the views are incredible. Turn around and look where you came from…you can see the Sliding Sands Trail as it switchbacks up the rim of the crater.

Looking back at the Sliding Sands Trail. If you look closely, you can see the trail as it switchbacks up the crater rim.

Halemau’mau Trail

At the far side of the Halali’i cinder cone you will reach another trail junction. Turn left to continue to the Halemau’u Trail (follow the sign to Park Road, which is 6.1 miles from this point according to the National Park Service sign).

Sandy Trail

OPTIONAL DETOUR: Turn right here to hike to Kawilinau, the Bottomless Pit. It’s about 0.4 miles one-way and it will add about 20 to 30 minutes onto the hike.

From the Halali’i cinder cone, the trail is flat for a bit. The trail is still sandy here but that will be ending soon.

Haleakala Trail Sign

The next trail junction is for the Silversword Loop. You can go right or left here; both trails meet up again 0.3 miles later. Even though this is called the Silversword Loop, we saw very few silverswords here.

Silversword Loop

Beyond the Silversword Loop, the sandy trail is replaced with a rocky, compacted dirt trail. Now you will hike through a rocky volcanic landscape. Plant life reappears and that massive rock wall off in the distance…that’s the rim of the crater. Eventually, you will be making your way up that giant chunk of rock.

The rim, and the final climb, is hidden behind the clouds in this photo. But you get a better idea of what you will be hiking up in the photo below.

 

Holua Cabin

Holua Cabin

Once you reach the Holua Cabin, you have about 3.8 miles to go and 1,300 feet of climbing. It’s still flat for a bit, as you hike through more volcanic terrain and then a field of high grass.

Halemaumu Trail

Just past the 8.5 mile point, you reach the rim of the crater. For the next 2 miles, the trail climbs out of the Haleakala crater. It’s a relatively short, intense, uphill hike. The trail is very rocky here, so a lot of the time you will be watching where to put your feet. Take your time, be careful, and when you need to, pause to enjoy the view.

Timing is everything. When Tim and Tyler did this early in the morning, the sky was clear and they had a great view of the crater. By the time Kara and I got here, in late morning, clouds moved in so we didn’t have much of a view. But the mist helped keep us cool.

With 0.7 miles left to go, the switchbacks end. But the trail does not flatten out here. You are still traveling uphill and will ascend a bunch of steps before reaching the end of the trail.

The hike ends at the Halemau’u Trailhead. In this parking lot, there is a restroom if you need one.

Transportation Logistics

The Sliding Sands Loop is a point-to-point hike, so you will need some sort of transportation to get between the trailheads. There are no shuttles in Haleakala National Park.

If You Have Two Cars

If you are traveling as a group, you can drive two cars to the summit. Park one vehicle at the Halemau’u Trail parking lot, drive to the Visitor Center in the second vehicle. Park here, and, as a group, hike back to the Halemau’au Trail parking lot. Once finished the hike, drive back to the Visitor Center to retrieve your car.

Hitchhike

The National Park Service recommends hitchhiking. Park in the Halemau’u Trailhead parking lot and walk out to the hiker pick-up area on Haleakala Highway, just a short walk from the parking lot (GPS coordinates: 20°45’11.0″N 156°13’47.0″W). Hitch a ride with someone up to the Visitor Center and start your hike from here.

The National Park Service recommends parking in the Halemau’u Trail parking lot and hitchhiking from here. That way, you are hiking back to your car and no longer have to worry about transportation logistics.

This method does work, because we have talked to people who have done it. But you could end up waiting awhile for a someone to pick you up, based on the time of day.

Split Up

This is what we did. It works well if you have more than two people (preferably at least 4 people).

Tim dropped me and Kara off at the Sliding Sands trailhead. Kara and I hiked the Sliding Sands Trail to the Halemau’u Trail. Meanwhile, Tim and Tyler drove to the Halemau’u Trail, parked the car, and then hiked the Halemau’u Trail to the Sliding Sands Trail. We crossed on the trail, Tim gave me the car key, and we each finished the hike. I drove up to the Visitor Center to pick up Tim and Tyler.

To do this, you need 2 people in your group who can drive.

PRO HIKING TIP: There are a few spots on the trail where you could miss each other. The Silverswords Loop is one of these places. We both agreed to take the western side of the loop, and good thing we did, because this is where we crossed paths. Had one of us hiked the other side of the loop, we would have missed each other. Also, make sure you know the hiking route. In the crater, there are several trail junctions, and if you or the other group makes a wrong turn, you might miss each other. There is no cellular service in the crater so you will not be able to communicate by phone.

Sliding Sands Trail Out-and-Back

If you don’t want to hitchhike, or if you don’t have 4 people in your group to exchange keys, or if hiking 11 miles just sounds like torture, you can hike just a portion of the Sliding Sands Trail.

I highly recommend hiking a portion of the Sliding Sands Trail while you are in Haleakala National Park.

You really don’t have to go far for truly great views. From the Visitor Center, you could hike to one of the first overlooks along the Sliding Sands Trail, snap a few photos, and return to this Visitor Center. This would be less than a mile of walking and take 30 to 45 minutes.

For those feeling a bit more adventurous, hike 2.5 miles down the trail, take lots of photos of the crater, see the silverswords, and return to the rim.

The full Sliding Sands Trail hike is about 11 miles round trip. This hike takes you to the crater floor and then you retrace your steps back to the Visitor Center. In my opinion, it’s better to hike the Sliding Sands Trail Loop…you will get to see more of the crater and you will have less elevation gain than hiking back up the rim on the Sliding Sands Trail.

What to Bring on the Hike

We did this just after sunrise. We were all dressed in long pants or leggings and long-sleeved shirts. It is windy and cold at the start of the hike, but once you hike down into the crater, there is less wind and it feels a lot warmer. Kara and I regretted wearing black leggings on this hike. I recommend wearing shorts, a short-sleeved shirt, and bringing a few extra layers that you can remove as you get warmer.

Bring a rain jacket, just in case it rains. It’s usually dry in the crater, from what I have read, but a rain jacket also gives you some protection from the wind (which can be a lot).

Hiking shoes. You can get by with a good pair of walking shoes or running shoes but hiking shoes will give you more traction, particularly if you plan to hike the Halemau’u Trail.

Water and snacks. Bring at least 2 liters of water per person.

Sunscreen, hat, and sunglasses. There is no shade on this trail.

Camera. Even a smartphone will do.
