Hosmer Grove

The main trail at Hosmer Grove is the Hosmer Grove Nature Trail. It's a self-guided loop that winds through the experimental forest. Hikers generally find it to be an easy and leisurely walk, making it suitable for beginners and those looking for a gentle stroll. The trail is approximately 0.6 miles (1 km) long.

While Hosmer Grove doesn't feature dramatic panoramic viewpoints like the summit of Haleakalā, its unique natural feature is the experimental forest itself. You'll encounter a diverse collection of non-native trees like pine, spruce, cedar, and eucalyptus, planted over a century ago. The trail also offers excellent opportunities for birdwatching, as it's a critical habitat for several endemic Hawaiian honeycreepers.

For the best chance of spotting and hearing the endemic Hawaiian honeycreepers, such as the 'I'iwi and 'Apapane, the early morning is highly recommended.

Hosmer Grove stands out due to its unique history as an experimental forest, showcasing a diverse collection of non-native trees planted in the early 20th century. This creates a lush, green environment that contrasts sharply with the often barren, moon-like landscape of Haleakalā's higher elevations. It's also a renowned haven for endemic Hawaiian honeycreepers, offering unparalleled birdwatching opportunities not found in other parts of the park.
