Came here in mid-July. It's a national park, so there's a great interpretative center and a junior ranger program with an awesome badge (space-themed), but I just couldn't get over the camp sites. It's all lava flow (duh) so there's very little vegetation, lots of rocks, and very little space in between the few sites. While there's a couple that have a tiny bit of privacy due to the walls of rocks, most are right in the open, and some of the spots are so tiny they barely fit a tent. Not sure if I'd go back.
