Haleakala's Sliding Sands
(4.0 miles out & back) - Explore cinder cones and old lava flows from within Haleakala, possibly the largest dormant volcano on the planet. Formed by erosion rather than volcanic activity, the valley at the summit of Haleakala boasts much to marvel at and the packed cinder and soil underfoot makes for a relatively easy hike. Here you''ll find the silversword, an endangered plant found nowhere else on Earth with an alien appearance that compounds the other-worldly appearance of this remote location.
