I’ve been caving in Utah for about 20 years. Really cool experience, but you need to be careful. Note that a permit is required, you need to get it from the BLM office in Fillmore before you head out. There have been some tragic accidents in other areas. Ensure people know where you are and when you’re due back just in case, wear a helmet and carry a backup light source. Very cool to combine this with dispersed camping though on the BLM land surrounding the site. I’ve rarely seen anyone else out here.
