Descend into the dark volcanic underworld of the Subway Cave lava tube for a short yet highly memorable hike. Twenty thousand years ago and just 15 miles north of Lassen Volcanic National Park, the ground broke apart and huge volumes of volcanic rock poured forth to create the enormous expanse that is the Hat Creek Lava Flow. Exposed to the air, the top of the lava flow began to cool and solidify, while molten rock below continued to flow - insulated by the now solid roof and creating lava tubes which carried the red-hot rock miles from its source. Subway Cave is a section of lava tube less than a third of a mile long, located between two areas of ceiling cave-ins. Substantial concrete steps have been constructed at both ends of the cave, providing easy access for all would-be spelunkers.

Easy hike with a lot of well maintained graphic information along the way. Bring flashlights and warm clothes! Kids loved it.

Good for kids, BRING a flashlight! Our 3 year old son loves it. Ground is really bumpy so hold hands, it's a great experience!

Short hike through a naturally formed tunnel created by ancient lava flow. We didn't have time to travel to Lava Beds, so I was pleasantly surprised to stumble upon this spot just off the main highway between Lassen Volcanic NP and Mount Shasta. Be sure to bring decent walking shoes, flashlight and light jacket. There are no lights inside except for a handful of informational markers throughout the tunnel, which explain where you are and what you are seeing. Depending upon your pace the hike should only take 30 min - 1 hour
