"A striking pit crater hike that crosses a vast expanse of cindery basalt formed in a spectacular 1959 eruption that sent lava nearly 2,000 feet into the air; the loop involves descending lush inner walls, walking across a broad, cracked lava floor where heat-related buckling is visible, and climbing back up the opposite rim for sweeping, otherworldly volcanic scenery. It’s a physically rewarding trail that leaves hikers hot, tired, and exhilarated by the scale of the landscape." - Flora Stubbs Flora Stubbs Flora Stubbs is the executive editor of Travel + Leisure.
