Ok, you twisted my arm...
Hosmer Grove Campground is a small set of primitive sites located in the Kīpahulu region of Haleakalā National Park, at the cloud line. This means it will get cold, especially at night, and even in the summer. Come prepared for this nice break from the Maui beach heat. The spaces are first come first serve, summer will likely be busier so come early. No permit needed. Fairly easy to pack in as well.
There are grills and nice picnic tables available at each site, but no campfires are allowed, so you must use the grills for your cooking. All the better to see the stars at night, right? Portable water is available and there are also put toilets only. Please be respectful of other campers since the area is so small.
Be prepared to be woken early to the sound of an array of birds, and even a clearly lost rooster up before dawn. The best thing about Maui, is that it’s an island formed out of nothing from a volcano, meaning it did not break off from a land mass carrying with it all the variety of animals and insects campers often find troubling. In fact, typical tropical concerns like venomous snakes and large cats are nonexistent here. A very safe place, animal wise, to camp, but do be warned of flash floods when hiking the area and come aware of the conditions and also prepared with a first aid kit, as outside help is far and difficult to reach. Towers were recently put in to assist with calls out, but in the valleys and at high elevations you will often find it hard to get reception. And help us an hour or more away. So hike with caution.
Sites are fairly level, close to each other, and on soft grass. The route to this area via the Hāna Hwy is almost worth the trip in and of itself, it’s truly a gorgeous area at all elevations.
Be sure to take advantage of the many guided hikes (also for safety reasons) offered by the national park and local private companies. We took a GREAT waterfall rappelling trip with Rappel Maui and enjoyed all their info about the area and expertise in rappelling. Be prepared for mosquitos, however we really didn’t encounter too many in June.
Check out the Pools at ‘Ohe’o and the many many waterfalls around the Nat Park as well as the state park while there. And the rocky, rough-waved cost on that side of the island (not great for swimming but so so beautiful).
