Halema'uma'u Trail

Descend 425 feet (130m) at the southern edge of Kīlauea Caldera through a rain forest that has been re-established numerous times.

You may return by the same route or proceed to the Byron Ledge Trail. From there continue to the Kīlauea Iki Trail and on to Crater Rim Trail that will bring you back to Kīlauea Visitor Center.

Please note the Halema‘uma‘u Trail across the caldera floor is closed beyond stop 10 due to the active eruptive vent in Halema‘uma‘u Crater.
