One of the places, while in Hawaii, we did a tour of was Volcanoes National Park. Our bus driver and tour guide looked and sounded like Tommy Chong. We walked on harden lava, saw steam coming up from the ground, live lava flows and the Thurston Lava Tube. "Lava tubes are natural conduits through which lava travels beneath the surface of a lava flow, expelled by a volcano during an eruption. They can be actively draining lava from a source, or can be extinct, meaning the lava flow has ceased and the rock has cooled and left a long, cave-like channel." It was a 20 minute walk from the parking lot on a gravel path through a thick and beautiful rain forest before reaching the lave tube. Inside it was dark and moist with a few scattered lights to show you the way through. It was amazing.
Here are some pictures of me, my hubby, my son and his friend walking through the tube.
