A world away from the dramatic, rocky lava flows atop the Haleakalā volcano lies a lush, forested haven for birds called Hosmer Grove. In the early 20th century, a forester named Ralph Hosmer established this plantation of non-native trees to determine which trees would be suitable to grow for timber on Maui. A fraction of the original species remain, and a fraction of those have become aggressively invasive among native Hawaiian vegetation. The park is working hard to manage the spread of alien species, including several types of eucalyptus trees that have thrived there.

The short interpretive loop passes through sections of vegetation dominated by alien and native species, and there is signage identifying several types of trees and shrubs. A viewpoint by a short fence provides a beautiful view across a gulch filled with native trees.

On this trail you're likely to hear and see native Hawaiian honeycreepers. These small, brightly colored birds have curved beaks that allow them to feed on nectar.

Camping is available at the campground at the trailhead on a first-come, first-served basis. Whether you enjoy an early morning stroll after breakfast at your campsite or swing through on a quick stop on your drive down the mountain, Hosmer Grove is a great rest stop where you can learn more about Hawaii's forests and enjoy the cool shade high up in the clouds.
