Manukā Natural Area Reserve

Manukā preserves native dryland forest that has nearly vanished from the rest of the state. Brush mud and seeds off your shoes before walking the trail to slow the spread of rapid ʻōhiʻa death and invasive plants. Do not collect plant material — most species are protected; some endangered. Do not stack stones or leave anything in the lava tubes. Bring a flashlight if you want to enter the tubes; they are unlit and the floors are uneven. The park is free, and the absence of fees and rangers means visitors are responsible for their own behavior.
