West of Susanville, just N of the 44/89 junction on Highway 89, across from Cave Campground is the Hat Creek Subway Cave. We stopped here on our trip from Arizona to Washington in the hot July sun. It was the 10th and 11th of July with record heat and we were staying at the Cave Campground in a tent. During the day, it was wonderful to visit this cave. Just sitting on the steps leading in and out of the lava tube was refreshing, so if you aren't an avid spelunker, you can still enjoy the cool outside. It is obvious from looking down on the cave that the entrance was formed by a cave-in of the lava tube as there are lots of big rocks piled around. It is way too dark to attempt exploring the cave without a flashlight. If you don't have a good flashlight, one can be rented from the Old Station store nearby. The floor of the cave is very uneven so be careful. I have included several pictures of the entrance and exit. There is a trail around the cave and signs explaining how the lava tubes were formed, etc. This is a very informative little hike and one the whole family can enjoy. If you plan to stay at the Cave Campground, it is well laid out and has flush toilets. There are three near-by restaurants, but none are open on a reliable basis. The 11th was our anniversary and we ended up eating at a hamburger stand 12 miles from the campground because both of the closer restaurants were closed.
