Review:
This lava tube can be found in Lassen National Forest in the northern part of California, not too far from the Lava Beds National Monument. Subway Cave is a large, open lava tube that runs for around 1/3 of a mile. It features quite a bumpy floor and some very interesting rock formations, making it a must visit for lava tube lovers in California. Guided tours run at this location in the summer.
