Comfortable with standing, walking on uneven ground, and a few short scrambles; suitable for most active families.
Venture into Lava River Cave with an expert naturalist and learn to read the language of basalt. This three-hour guided lava tube tour from Bend combines hands-on geology, low-light photography tips, and practical advice for a safe subterranean adventure.
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.

Caves remain around 45°F year-round—bring a fleece or insulated midlayer even on warm days.
The cave is a wild environment with uneven rock and short scrambles—hiking boots or rugged trail shoes reduce ankle injury risk.
Carry water, a snack, and a camera; leave large packs in the vehicle to move through narrow passages comfortably.
Tours depart promptly from the Fred Meyer meeting point—plan to arrive 10–15 minutes early to check in and complete the waiver on your phone.
The tube formed during Newberry volcanic activity when basaltic lava flowed and drained, leaving long subterranean passages; the area has been studied and visited by locals and early naturalists for over a century.
Keep to guidance to avoid damaging fragile features—no graffiti, no touching delicate formations, and pack out all trash; guided access helps manage human impact.
Supportive, closed-toe footwear for uneven, rocky cave floors.
Keeps you warm in the cave’s constant 45°F temperature.
Hydration and a light snack keep energy up during the three-hour outing.
Helps capture low-light cave textures on long exposures without blur.
