Set in the cooler and windier climes of Haleakala’s cloud belt, Hosmer Grove Campground is just below the 7,000 foot summit area. Camp is on a grassy area next to shrub land, and the alien-like forest of Hosmer Grove. This is an excellent spot to get up for an early hike (you’ll likely be awakened by animal and bird noises), on the self-guided nature trail that begins and ends at the campground. It’s really difficult to pinpoint what kind of weather you’ll encounter, so come prepared to handle rain and nighttime temperatures in the 30s or below. Daytime highs can be cool, but you may also score a pleasantly warm day in the 70s.
