Cinder Cone Trail
Though set in the park's remote northeastern corner, this is one of its most fascinating trails, as it offers views of a dazzling variety of volcanic features, including Painted Dunes, Fantastic Lava Beds, and Prospect Peak. It's a somewhat challenging undertaking, because the 4-mile round-trip hike to the cone summit requires a steep 845-foot climb over ground that's slippery in parts with loose cinders. For a better understanding of the geology along this hike, pick up an interpretive brochure at the trailhead or visitor centers. Moderate–Difficult.
