Day Hike - Mauna Ulu / Pu‘u Huluhulu
Experience a lava landscape from the 1969-1974 Mauna Ulu flow. Walk by lava tree molds and climb 210 feet (64m) to the top of a forested cinder cone, Pu‘u Huluhulu (hairy hill). View Mauna Ulu's steaming sheild, which is similar to the now active Pu‘u ‘Ō‘ō cone in the distance. On a clear day you can see Mauna Loa, Mauna Kea and the Pacific Ocean.
Of interest: Pāhoehoe and ‘a‘ā lava, kīpuka (old land surrounded by new land), lava tree molds, cinder cones, lava rampart, native pioneer plants and trees and panoramic vista.
Dependent on the wind direction, volcanic fumes may be present along this trail.
Protect delicate lava formations. Surface patterns and lava trees are fragile. Reduce your impact. Please do not touch these formations.
