What to Expect

This short loop through Hosmer Grove feels like stepping into a botanical time capsule. The trail winds through a planted forest of non-native trees — Norfolk pines, eucalyptus, cedar, and spruce — before transitioning into native Hawaiian shrubland where you'll spot endemic species like ohia lehua and mamane. The contrast between the two halves is striking: one minute you're in something that feels like a Pacific Northwest forest, the next you're surrounded by plants found nowhere else on Earth. The path is well-maintained and mostly shaded, with gentle elevation changes that barely register in your legs. Birders will want to linger — this is one of the best spots on Maui to see native Hawaiian honeycreepers, including the endangered apapane and iiwi flashing crimson through the canopy. Perfect for families, jet-lagged arrivals, or anyone looking for a mellow leg-stretcher before tackling the crater.

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.

Pro Tips

Trail Tip

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.

Trail Tip

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.

Trail Tip

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.
