Lava Tube Cave Tour in Bend: Wild Cave with Naturalist Guide

Three hours in a wild lava cave where you walk unlit terrain and a naturalist explains the geology beneath you

A guided tour of Bend's lava tube caves takes three hours underground with a naturalist guide, helmet and headlamp. Wanderlust Tours is the only company permitted to lead groups into these wild caves, which have no paved paths or installed lighting. The cave floor is mostly flat, though you'll encounter uneven rocky terrain. The temperature stays at 45 degrees Fahrenheit year-round. Groups stay small, maximum seven guests, and the tour includes transportation from the office in an air-conditioned van.

The experience

Three hours underground means you spend the bulk of a morning or afternoon in the cave itself, with travel time built in. The lava tube networks beneath Bend were formed thousands of years ago by volcanic activity, and a naturalist guide walks you through the geology as you move through the system. You'll wear a helmet and headlamp. The cave has no installed lighting, so your headlamp is how you see. The walking surface is mostly flat, but you will step over uneven, rocky terrain, and the entrance requires stepping through a gate with about 14.5 inches of clearance from top to bottom.

Wanderlust Tours provides the helmets, headlamps and transportation in their passenger van from the office to the cave and back. Wear closed-toe hiking boots or sturdy running shoes. The operator recommends a fleece jacket and jeans because the cave stays at 45 degrees year-round and you'll pick up dust. Children as young as five are welcome, and the tour is described as easy difficulty. The challenge is mostly the entrance gate and the uneven ground, not steep climbing or tight passages. Groups max out at seven guests, so you're never in a crowd underground.

Fill out a waiver on your phone before you leave the office. Bring a water bottle. Snacks are welcome but not provided. If you have questions about the cave's difficulty or the entrance clearance, contact the operator directly before booking.
