Explore the third longest lava tube cave in the country! Descend with us for an exciting beginner caving experience—perfect for escaping the summer heat! We will walk 2.5 miles underground and explore the tunnels within Mt. Saint Helens National Forest. This trip is rated ‘easy’ due to the relatively little elevation gain. Be prepared for chilly temperatures as the cave stays 42 degrees (F°) year-round, leading to a unique summer outdoor experience. Come scurry around in the dark with us!

Pre-Trip Meeting: 7/9 at 5:00 PM in the ODP Conference Room
