The Halemauu Trail is a 8.5 mile full day hike that takes you down 4 miles of switchbacks to the crater floor and ends at the start of the Keoneheʻeheʻe (Sliding Sands) in the Haleakalā Crater.  

From here you’ll connect and it is another 2.5 miles up Sliding Sands Trail to get out of the crater.  So in total, the Halemauu Trail down and out of the crater is 11 miles total.

Maui has tons of hiking trails but if you’re an avid hiker looking for epic views inside a dormant volcano, the Halemauu Trail is right up your alley.

Not only will you be greeted with epic views of the inside of Haleakala crater but along the way you’ll see exotic plant life like the silverswords.  

These are a rare and endangered plant that can only be found in Haleakalā crater, Mauna Kea and Mauna Loa on the Big Island of Hawaii.

  • Difficulty: Difficult
  • Duration: Full day
  • Elevation Gain: 1100 feet (only on the Haleamuu Trail)
  • Distance: 11 Miles in and out of the crater connecting with Sliding Sands Trail

How to Get to the Halemauu Trailhead

Halemau’u Trail is located inside the summit district of Haleakala National Park.  The summit district of Haleakala NP is located upcountry Maui.  Depending on which part of the island you are staying on, the drive will take at least an hour and a half drive minimum.

Travel Tip:  Haleakala National park has 2 separate entrances, the Summit and Kipahulu District.  These districts do not connect to each other.

It cost $30 for an entrance fee which is valid for 3 consecutive days.  This is valid for both the Kipahulu and Summit Districts.  An annual National Parks Pass also grants you access to the park which will be your cheapest option.

Once inside the summit entrance, you will drive up to about 8,000 feet.  The parking lot for the Halemau’u trailhead will be on the left between mile marker 14 and 15.  

There will be a sign saying ‘hiker pick up’, the trailhead parking lot will be around the bend after the sign on the left hand side of the road.  There are restroom facilities in the parking lot.

When is the Best Time to Hike the Halemau’u Trail

The best time to hike the Haleamauu Trail is starting early in the morning.  Since this is a full day hike, it will require a full day to complete if hiking to completion.

Reservations to enter the summit of Haleakala National Park are required from 3-7 as watching the sunrise atop Haleakala is a popular tourist activity.  Plan on starting the hike anytime after 7am unless you make reservations. 

It is possible hike Haleakala any time of year as the weather is pleasant all year round.  In the winter time temperatures are 10° cooler.   The summer months have a less likely chance of rain.  On a sunny day it may feel cool but don’t forget to wear your sunscreen as you’ll get burnt. 

Hikers must be properly prepared for high altitudes and cold, rainy conditions at any time.  Weather  in the Summit Area is unpredictable and ever-changing.  Prepare for harsh UV rays, wind, rain, and cold temperatures year-round.

Practical Trail Information

For the purpose of this article, we’re going to start the hike at the Halemauu trailhead which takes you down the switchbacks and across the crater floor to Sliding Sands trail.  From here you would hike up Sliding Sands to the summit of Haleakala.

Then you’ll either have to catch a ride back to the trailhead parking lot or hop in the car if you used the two vehicle approach (meaning park one vehicle at the summit and one vehicle at the trailhead).  Personally, the last thing I want to do is hitchhike my way back to my car after I’ve been strenuously hiking all day.

A lot of people that are short on time or don’t want to hike Halemauu Trail in completion will park at the Halemau’u trailhead, hike down to the crater floor and back up the switchbacks with totals about 8 miles.

Switchbacks inside Halakeala Crater maui Hawaii

I always park a car at the Halemauu Trailhead and hitchhike to the summit because there’s a hitchhiker pickup area nearby (marked by a sign) and its much more enjoyable to hitchhike at the beginning of your hike opposed to the end.  From the top, you’ll hike down Sliding Sands and eventually up the switchbacks.

Hiking these trails in this direction is also much easier.  It’s called Sliding Sands for a reason and its very difficult hiking up a sandy trail for 2.5 miles especially when its at the end of a strenuous day versus down a slidey trail in the beginning.  Hiking up the switchbacks compared to down is also much better for your knees.

From the parking lot head towards the trail, you can’t miss it.  The hike begins in a brushy, forest and you won’t see sites of the crater until about 0.75 miles in.

Rainbow Bridge on the Halemauu Trail

Next up is an area called Rainbow Bridge, this area of the trail is narrow and great for pictures – if its not covered in clouds of course.  The next couple mile take you along the cliffs offering dynamic and unparalleled views of the crater in all of her glory.

The Halemauu trail is narrow and at times steep as it twists and turns down the side of the crater to the crater floor.  If you get a later start, prepare to be hiking through misty clouds as they tend to accumulate around the top of the crater as the day progresses.

After a knee crushing 1000 feet decline into the crater you’ll soon run into the Holua cabin,  You can’t enter these cabins unless you acquire a permit and they are hard to come by.  There is also a first come first serve campground here.

I’ve stayed at this Haleakala wilderness cabin several times and its one of my favorite adventures on Maui.

Continue on the trail past the cabin, you’ll start to climb again.  You’ll be cruising for about a mile until you come up on the Silversword Loop.  This is a short detour from the Halemau’u Trail that showcases a large cluster of ʻāhinahina if they are in bloom.  The āhinahina or Silverswords are a rare and endangered plant that can only be found on Haleakala, Mauna Kea and Mauna Loa on the Big Island of Hawaii.

The next three miles or so takes you along the crater floor where the back drop is red, orange, pink and green colored cinder cones mixed with volcanic rock and a black sand trail.  The dramatic change of colors and scenery are nothing short of amazing.

You’ll eventually meet up with the Sliding Sands Trail.  There’s a hitching post and some rocks to sit on, take a rest and enjoy a snack or sandwich.  From here it’s about 3 miles up Sliding Sands to the Visitors Center parking lot.
