Subway Cave

Explore the underground world of a lava tube. The self-guided trail is approximately 1/3 mile long and the cave is completely dark, so don't forget to bring a flashlight.

The floor is rough and jagged so wear sturdy shoes. A light jacket will ward off the chill as the cave remains a cool 46 degrees F.  Neither hardhats nor crawling is required!
