I went through Ape Cave on the south side of Mt. St. Helens when I was a teenager and loved it… then I got to take my kids and DH through it too 🙂 It’s a 2-mile long lava tunnel, pitch dark, full of huge boulders to be scrambled over, and definitely not for the claustrophobic! I need to do this again… when I took K&T through it was recently after a knee surgery and I didn’t have all of my leg strength back, which does come in handy when scrambling over boulders the size of cars.
