Subway Cave

Not far from the junction of Highways 44 and 89 above Old Station is an interesting volcanic attraction that you can walk through. It is a lava tube about 1,300 feet long that was created less than 20,000 years ago when lava flowed over this area. Tubes are formed when the top part of the flow cools and hardens but the interior continues to flow until drained, leaving behind a tube. Access into the tube are found in two places where the roof collapsed sometime in the past. You are warned to bring at least two sources of light (flashlights preferably) and warm clothing. Without illumination, it is pitch black down there.
