Lyon Arboretum is part of the University of Hawaiʻi and a public botanical garden. We are nestled in the back of Mānoa Valley, just five miles from the bustle of Waikiki. Lyon Arboretum has over seven miles of hiking trails and boasts more than 6,000 taxa of tropical and sub-tropical plants on our nearly 200 acres.
