The Kalopa Nature Trail is an easy loop through the heart of a rainforest. The forest has an upper canopy of large, old growth ‘ohi’a trees, and beneath is an understory composed predominantly of smaller native forest trees and shrubs. Ferns are also abundant. About 25 different native species of trees, shrubs and vines can be viewed along the trail, though several occur only as a single individual. This is a good family walk. Allow about an hour to complete a leisurely walk.
