“One of the best spots on Maui for nature-viewing, the path winds through native and nonnative plants”— Megan W
Family Friendly Close to parking, bathrooms and water make this a convenient destination. Mellow terrain, different tree types to identify and wildlife to find make it suitable for kids.
Some history- in 1910, Ralph Hosmer planted non-native trees (eucalptus, sugi pine, spruce, cedar, Douglas fir, deodar, etc.) here in hopes of creating a timber industry and reviving the watershed. Hosmer found that these introduced species adapted to Hawaii well enough to survive, but they did not grow fast enough to make harvesting commercially viable. The National Park Service works to make sure that these non-native plants do not escape from this area.
