Subway Cave
A lava tube formed about 20,000 years ago, which you can walk through for about 400 m of pitch-black tunnel with your own flashlight.
Subway Cave lies beside Highway 89 in Lassen National Forest. It is a tube-shaped cave left behind when the surface of a lava flow cooled and the molten lava inside drained away. The self-guided walk covers about 400 m over a rough lava floor, with no lighting, so bring a strong flashlight and sturdy shoes. The cave stays cool, making it a good summer escape from the heat. Admission is free, and it is convenient to reach from the nearby former railroad town of Old Station or from the north entrance of Lassen. It can be combined with Burney Falls in a day trip.
