Hosmer Grove Trail
What to Expect
Safety Advisory
At nearly 7,000 feet elevation, temperatures can drop into the 40s even on summer mornings — bring a layer, especially if you're coming straight from sea-level Maui where it was 85 degrees an hour ago.
The trail can be slick with mud and fallen leaves after rain, particularly through the shaded grove section — wear shoes with some grip rather than flip-flops.
Trail Details
- 1
Arrive early morning when the native birds are most active — the endemic honeycreepers feed in the native shrubland section and are noticeably quieter by mid-morning.
- 2
Pair this with the nearby Haleakala summit sunrise visit: hike Hosmer Grove afterward while you wait for the visitor center to open, since the trailhead is right off the park road at about 6,800 feet.
- 3
Bring binoculars specifically for the native forest section on the loop's back half — the iiwi (scarlet honeycreeper with a curved salmon-colored bill) tends to perch in the ohia trees and is nearly impossible to appreciate with the naked eye.
