Rating: ★★★★★

In a nutshell: Haleakala Crater is the most popular attraction in Upcountry Maui. Stunning sunrises, panoramic out-of-this-world landscapes, birds-eye views of the Maui central valley, and flora and fauna that exist nowhere else in the world.
Minuses: The air is thin, and hiking here is not for the less fit.
Sound-bite: “Oh my Lord, it is cold up here!”

Haleakala National Park covers the summit area of the larger of the two volcanic mountains that make up Maui. The National Park’s boundary has fingers that extend down the Hana side of the mountain, all the way to the ocean. (The entire park includes the Kipahulu area, where Ohe’o Gulch (Seven Pools) and Pipiwai Trail are found – this article includes only the Summit Area.)

The Legend of Maui

Haleakala literally means “House of the Sun.”

According to Hawaiian legend, the goddess Hina complained to her son Maui that the sun moved across the sky too fast for her tapa cloth to dry. The next morning before sunrise, Maui went to the top of Haleakala and waited in hiding. When the Sun awoke, Maui lassoed him, and beat him into submission. Maui then made the Sun an offer he couldn’t refuse: he would let the Sun go, but in return the Sun would have to cross the sky much more slowly from that day forward.

The Sun agreed, Maui released him, and we’re now blessed with long sunny days!

Geologically Speaking
Speaking of “crater” this is a good time to explain that the summit area is actually not a typical crater formed by volcanic activity (such as you would see on the Big Island of Hawai’i.) Haleakala Crater is so gigantic because it was formed over eons as the result of erosion of the entire volcanic mountain top. Over this period of time, smaller lava flows back-filled the eroding valley, building up the floor of what is commonly called the Haleakala Crater. The cinder cones that dot the landscape here are the last of these most recent eruptions (and these individually have true volcanic craters.)

Like the oft misunderstood prune, there has been an effort to re-brand the Haleakala Crater area something more technically accurate (dried lava-mountain?), but I think the Maui Guidebook will just call it a capital-C “Crater” (as in place name) rather than the longer-winded (and far-less recognized) “Haleakala National Park Summit Area.”

Oh, and that dried lava-mountain you’re looking at isn’t actually done erupting yet. Haleakala is dormant, and (geologically speaking) it has erupted fairly recently. You’ll hear most guidebooks quote the more “hey that’s not that long ago” date of 1790, but that date is largely based upon deductions made from a notoriously bad map maker’s map not matching the coastal lines on an accurate map. When subjected to carbon dating, the rocks from that lava flow date to the 1600’s. (I don’t know about you, but my money is on the science nerds.) Haleakala is also expected to erupt several more times in the future. Since geological time is measured in the millions of years, our time on Haleakala (and Earth) is short enough that you can feel secure leaving the heat-reflective lava suit back home in the family fallout shelter.

Photography does the panoramic vistas no justice.

Stuff to Remember When You Visit
Remember to bring your sunscreen, plenty of water, and something else you may have left back home: layers of warm clothing. Overnight (yeah, before sunrise) temperatures can dip below freezing. Even during the day temperatures can be cold enough for a sweatshirt, or even a jacket – especially if you’re not getting any blood moving waiting for the yellow disc to rise above the horizon. Once the sun does rise, there is less atmosphere to scatter and absorb UV rays, so the sun’s skin-burning potential is actually stronger at these higher elevations than it is at the beach.

Oh, and while we’re on the subject of the beach and ocean – if you’re a SCUBA diver, the reduced pressure at the altitude of Haleakala is well below that of a pressurized aircraft. So be sure to observe the same degassing time rules you would prior to flying.

Also important to remember, if you go for a hike into the Crater, the hike in is deceptively easy. The hike out is another story. The thin air and elements (sun, wind, occasionally rain) means you’ll likely take twice as much time (and way more than twice the effort) to get out than you spent hiking in.

Sunrise is the most popular time here. Mark Twain called it “the sublimest spectacle I ever witnessed.” Words can not do this event justice, it is a feeling to be experienced. Conditions are typically conducive to spectacular sunrises – but that doesn’t mean they’re guaranteed. Arriving here for sunrise means getting up very early. I usually suggest to friends visiting to go on their first or second morning (while their body is still on an earlier time-zone.)

Sunrise Scheduling 101
1. You want to get to the summit 20-30 minutes before the sunrise time in the table below. (The weather widget on the sidebar has today’s sunrise & sunset – click “Hale” at the top for exact time.)
2. Leave yourself an extra 15-30 minutes (depending on how far you’re driving) for slow-pokes and paying the entrance fee.
3. If you’re driving during peak traffic times (typically during daylight hours, and especially from West Maui) drive times can take longer.

When the Sun Sets
A strong “second-best” next to the sunrises, sunsets are still absolutely spectacular up here. If you just find that you just can’t rationalize waking up before the crack of dawn on your vacation, hanging out for the sunset might just suffice.

Barring special closures, the park is open 24-hours a day, so you can come up here and leave any time you want.

Since there is less atmosphere up here, combined with being above turbulent atmospheric conditions, and virtually zero light pollution, the summit area of Haleakala also ranks among the very best sites in the world for viewing the night sky. Astronomers can expect to see objects up to 7th magnitude. If you don’t know what that means, magnitude is a measurement of brightness. The higher the number, the dimmer the object. Remember the bag of tools the space station astronaut accidentally let go of last year? That bag of tools shines in the night sky at 7th magnitude. It is so dark up here that if you know where to look, you can literally see a backpack sized bag of tools from Haleakala as it orbits Earth 174 miles above!

Flora & Fauna
Haleakala National Park has more endangered species than any other National Park in the country (including species which are not native.) The park is chock-full of facts about all the plants and creatures unique to Haleakala. If you like learning about wildlife, take the time to stop in the visitor’s center, and also to read the many educational and informational signs that the NPS has posted around the parking areas and trailheads. (You may also want to stop in the visitor’s center even if you’re just here for the views – they have one of top drive-up Crater views.)

One of the plants which is native to only Haleakala is the Ahinahina, or Haleakala Silversword. Living only at the summit of Haleakala, the Silversword has developed some interesting adaptations for survival. One of the lesser-known adaptations is that the leaves of the Silversword form at an angle so that the older leaves focus the warming energy of the sun on to the youngest leaves. Threatened by near extinction in the 20th century, the Silversword is now considered a triumph of conservation efforts. This plant lives between 15 and 50 years, blooming only once before dying. When a Silversword goes into bloom, it puts out an impressive stalk of flowers that can be as tall as a person. The stalk contains hundreds of what look like tiny purple, wine red, or sometimes yellow sunflowers radiating in all directions. If you are hiking here in the summer, you will likely see several Silverswords in full bloom.

Car strikes are a top threat to Nene in the park.

The Nene is another Haleakala conservation success, although these creatures are still precariously endangered. Years of hunting by introduced species (and people), the Nene became virtually extinct. With only 30 individuals remaining, in the 1960’s & 70’s a captive breeding program In England bred and then reintroduced the birds to Haleakala Park. Today a stable population of about 250 wild individuals populates the park, and some have even been sighted (including by yours truly) at much lower elevations.

Many guidebooks mistakenly call the summit of Haleakala the Nene’s native habitat. However, the summit area is not where these birds were once primarily found, but was chosen as a protective area to reestablish the species. A relative of the Canadian Goose, the zebra-striped birds were actually once common at much lower elevations. Since the Nene evolved with no natural predators, they also lay their eggs right on the ground which makes them easy-pickens for rats, mongoose, cats and dogs.

The Park Service used to offer dial-up forecasts, the phone numbers for which are still widely printed as fact in many guidebooks. Don’t bother calling these numbers, they are no more.

The NOAA offers forecasts – but keep in mind weather can change rapidly in this environment. The NOAA website will give you as accurate a forecast as you are gonna get.

House of the Sun (and beyond!)

Jack London wrote a spectacular account of his visit to Haleakala in 1907, as he ascends through the leeward side of Haleakala to the summit, through the crater and back down to Kaupo. The story continues tracing back along the East Maui ditch system back to civilization. Surprisingly, much of it is as accurate today as it was then.

Horseback Riding
This is the only other method besides your legs that you can use to get into the Crater. Pony Express Tours offers an outstanding ride that is worth every penny.

Downhill Bike Tours
The Haleakala Summit is also a popular place for launching downhill bike tours. Until 2007, tour companies brought visitors to the summit for sunrise, and then launched their multi-hour downhill tour right from the parking lots. However, a string of accidents, including a fatality, caused the National Park Service to ban commercial launching of bikes within the park boundaries. They call it a “stand-down” as it is intended to be a period where the NPS can re-assess their position – however, it has been extended, and does not look likely that the activity can guarantee the level of safety the park service feels appropriate. You can still rent bikes from these companies and launch yourself – however this is (ironically) more dangerous than being part of a group as you don’t have a protective buffer of a tour van blocking aggressive drivers from passing in unsafe areas. Alternatively, the tour operators do launch from just outside the boundary of the park, but this cuts out a significant portion of the ride. Speaking as someone who once lived on Crater Rd and observed many sketchy situations where lives were endangered, I would advise strongly that anyone interested in this activity become educated as to the risks, and how to minimize them.

Camping & Cabins
For hikers there are three cabins and two campgrounds inside the Crater. None have electricity or potable water. All are miles from your car, and can be strenuous hikes. For non-hikers, there is also a drive-up campground outside the Crater at Hosmer’s Grove.

You may have read elsewhere that you “literally must win a lottery to rent the cabins.” This is a bit of sensationalized exaggeration combined with outdated information. Cabin reservations, and current booking schedule, are now handled online at https://fhnp.org/wcr/ – this is great news for the chronically unlucky: the only luck involved is that no one has beat you to your dates. Operated by the NPS, each cabin can accommodate up to 12 hikers and rent is a steal at $60-75 per night.

Horse and Mule Rides
There are guided horse and mule rides into the Crater for experienced riders who don’t want to hike in. These are with private companies, and must be set up with them before visiting. One company that comes highly recommended is Pony Express Tours.

Waikamoi Preserve
Just inside park entrance alongside Hosmer Grove is the Waikamoi Preserve. This place is spectacular. I intend to do a full-page writeup in the future. The Nature Conservancy manages this fenced-off protected habitat of native cloud forest, and it is off-limits except to those on special hikes led by naturalists. Call 808-572-4459 to find out how you can join a group to glimpse of pre-Western-contact Hawai’i that very few will ever see.

More Info at the Park
There are programs ranging from 15-minute talks to half-day naturalist guided hikes offered most days of the week. You can just stop in the Visitor Center or call – the park phone number is 808-572-4400.

The National Park Service has some nice general summaries of the park on their website. Unfortunately they have not yet entered the 21st century, and don’t provide access to the majority of the wealth of detailed information they have about Haleakala there. The silver lining is that lots of this info is available in the Visitor’s Center, from both highly knowledgeable park staff, displays, and informational literature.

    My daughter, Kendra Brandstein & her friend, Julie Chan recently camped out in the crater on December 27. We had tried to get them into a cabin months before but no one cancelled. However, when they were there they met three people who were staying in one of the cabins with 12 beds? They were the only people in the cabin. They were very nice but did not invite them to share the cabin. This seems quite unfair. So my daughter and her friend were denied staying in a cabin. Can you please explain why two young women were denied access to a cabin in 40 degree weather?

      You have to book the cabin way in advance. Even if it sleeps 12 and not all rooms are being used. it’s on a first come first served basis.

      As someone that has booked and payed for the cabin in advance, I planned on having the time with my friends and family only. No strangers. Maybe the girls should have been a little more prepared to hike i.e. brought a tent if they didn’t have a cabin to stay in. Also would yo be asking this question if it would have been to you men???????

    Good points Deanne – you must make a reservation well in advance to get into the cabins. If you don’t you’ll need to be experienced and come prepared to camp in harsh wilderness.

    It is my understanding that the cabins are only rented to one group at a time, no matter how many beds they need. It is a shame that the folks in the cabin with ample space were not thoughtful enough to help two young women in over their heads in the wilderness. That clearly would have been the decent and right thing to do.
