The "Indian Tunnel" is the largest and longest of the lava tubes along the Caves Trail that can be accessed. To do so, you need to obtain a free permit at the Visitor Center. You will climb over rocks that can be slippery in places, but it is a unique small adventure. On the ceiling of the tube you can see lava stalactites formed as the river of lava pulled away from the ceiling, and molten material began to drip from the hot ceiling. The exit is about 800 feet further north.
