Hosmer Grove Campground, Mountainside campground in Haleakalā National Park, United States.
Located at 7,000 feet elevation, Hosmer Grove Campground contains six designated campsites with picnic tables and grills in a grassy area next to forest lands.
Ralph Hosmer, the first Superintendent of Forestry of Hawaii Territory, established experimental forest plots at this location in 1909 for testing different tree species.
The campground features a self-guided nature trail through introduced conifers and eucalyptus trees, representing early 20th century Hawaiian forestry practices.
Reservations are required through Recreation.gov at $5 per night, with a maximum stay of three nights within any 30-day period for up to six people.
Campers with overnight reservations receive automatic access to view the next morning's sunrise at Haleakalā summit without additional booking.
