The Craters of the Moon Lava Fields in Idaho stand as an otherworldly testament to recent volcanic activity, shaped by basalt flows and shield volcanoes. Here, guided by interpretive trails and the scent of cinder, visitors traverse stark, kneeling landscapes of young lava, cross basalt spatter and cinder cones, and enter the dark confines of the Crater and* Cave tunnels. The monument supports a surprising array of desert-adapted flora and fauna, and provides access to starry night skies and seasonal rim hikes. Practical tips: check seasonal opening, pack layered clothing for thermal swings, and use the designated routes and safety guidelines when exploring the more fragile cave systems.
