Underneath the volcano is a locker room type area with showers. It’s very damp, though, as was mentioned. We haven’t stayed there in a few years, but the last time we did, there wasn’t a hook in/near the shower area for a towel, which seemed kind of strange as the bench (the only place to really leave a towel and clothing) is across the locker room, several feet away. I threw my towel over the entrance to the shower area; it stayed pretty dry and then took my clothes into a restroom stall to get changed.
