At Volcano National Park we go to walk through a lave tube which was pretty cool. The lights in the tube give it a weird red glow and there is silvery moss as well that didn’t come out well in the pictures.
What is a lave tube? Wikipedia explains it better than I can Lave Tube.
It was fun to walk through and I couldn’t decide whether is was very hobbit like or dune like it was a very curious atmosphere.
