You step off the bus into a wind-scoured parking area and the air changes—cool, mineral-rich and steady at about 45°F. Helmets click on, headlamps glow, and the world above narrows to a dark mouth in the basalt. For the next three hours, Wanderlust Tours leads you through a slice of the planet where time wrote itself in molten rock: Lava River Cave, Oregon’s longest known lava tube. Inside, the cave swallows daylight and replaces it with a close-up of geology—pitted ceilings, pahoehoe flow lines, and the patient hush of rock that has not seen sunrise for millennia.
