One of the surprising number of caves here, this photo is just inside the entrance of Valentine, a large multi-tube lava cave that’s fun to explore. I also like Skull Cave (named after animal skulls, mostly). It used to have a pristine ice floor at the bottom, but that’s turned dark, uneven and much smaller due to people. Merrill Cave used to have an ice floor large enough for skating, but it melted recently due to global warming, drained into a hole, and opened up a warm air vent. The same sort of thing has happened to at least a dozen other caves here, so you’re too late for the underground ice experience here, forever.

And it’s definitely a cave park. Except for parking lots, few walk around above ground. In 2000 the 85,000 acre Caldwell Fire burned 2/3 of the park, so I’m not sure what’s left to see besides dead trees and, of course, the lava beds themselves, which are black, rough and inhospitable. I recommend going to the visitor center to borrow a large lantern if you don’t have one, otherwise it can be hard to see down the more distant passages. They also have helmets if you’re a smaller, more flexible person who is willing to try the many more challenging caves. And, if you’re wondering what type of caves they have here (Goblin, Lizard or Vampire), I have to say Ghost. The caves have a haunted atmosphere with many strangely cold corners deep in the earth. Enjoy!
