Symbol Bridge Trail,
Lava Beds National Monument
From the visitor center, a short drive to Skull Cave brings you to the Symbol Bridge trailhead. The trail is fairly easy and level, though many sections have loose, rocky surfaces. It follows the ridge of a collapsed lava tube to Big Painted Cave, where a thick layer of ice covers the floor. Temperatures inside remain cool, offering a welcome break from the summer heat. A short walk from the entrance of Big Painted Cave leads to Symbol Bridge, which contains several distinctive and easily visible petroglyphs. The descent into either cave can be challenging for those who are unsteady on their feet. Closed-toe hiking boots and proper caving gear are recommended for anyone planning to explore thoroughly. The Missing Link trailhead is located directly across from the Symbol Bridge trailhead.
Before entering the caves within Lava Beds National Monument, a free screening pass for the deadly bat disease White-Nose Syndrome must first be obtained from the Visitor Center or Fee Booth.
