Hosmer Grove is a distinctive experimental forest and natural monument nestled within the Summit District of Haleakalā National Park on the island of Maui, Hawaii. Situated along the cloud belt of the majestic Haleakalā volcano, at an elevation of approximately 2070 to 2130 meters (6,800 to 7,000 feet), this unique area stands out from the often barren, moon-like landscape of the higher elevations. It's renowned for its diverse collection of non-native trees planted over a century ago, alongside remnants of native Hawaiian shrublands.

What truly captivates visitors to Hosmer Grove is the vibrant contrast it offers to the surrounding volcanic terrain. Hikers often remark on the refreshing greenery and the lively sounds of birds that fill the air, a stark difference from the quiet expanses higher up the mountain. Many find the experience of walking among the towering trees, a mix of pine, spruce, cedar, and eucalyptus, to be a pleasant and educational adventure, especially after exploring Haleakalā's summit.

Before visiting, it's helpful to know that Hosmer Grove is easily accessible, located just inside Haleakalā National Park, a short drive from the entrance station on the way to the summit. The area features the Hosmer Grove Campground, the only drive-in campground in the summit area, offering amenities like picnic tables, BBQ grills, and potable water. Given its elevation, the weather can be cool and misty, so dressing in layers is advisable. It also serves as an excellent base for those planning to experience the famous Haleakalā sunrise.

The best time to visit Hosmer Grove for wildlife spotting, particularly for birdwatching, is typically in the early morning when the forest is most active. The primary activity here is hiking the self-guided Hosmer Grove Nature Trail, a family-friendly loop that winds through the experimental forest and offers insights into its history and ecology. This easy trail is perfect for a leisurely walk, providing a chance to stretch your legs and immerse yourself in nature.

Visitors consistently highlight the incredible birdwatching opportunities at Hosmer Grove. It's a critical habitat for several endemic Hawaiian honeycreepers, such as the 'I'iwi, 'Apapane, Hawaii 'Amakihi, and the Maui 'Alauahio. The chance to hear and potentially spot these rare birds, often described as a sound unlike any other, is a standout moment for many. Some hikers enjoy a peaceful breakfast walk here after witnessing the spectacular Haleakalā sunrise.

Whether you're looking for easy trails, a unique forest experience, or a chance for wildlife spotting, Hosmer Grove offers a memorable visit. You can explore various Hosmer Grove trails and discover the rich biodiversity of this special place.

    Hiking

    Although a campsite is located here, it is worth visiting this area. You get out of the car and hear the birds chirping in a way you have never heard before. This area was a forestry attempt to settle other tree species. A tour is really worth it, you learn a lot about the native birds and maybe you will also discover an I'iwi.

    Hiking

    'Haleakala's summit area and its barren moon-like landscape is a real treat for the senses. But if after exploring that region you find yourself longing for the company of green trees and vegetation, a hike among the Hosmer Grove Loop Trail's cedar, spruce, pine, eucalyptus, and more will surely be a pleasant adventure'
