Beautiful place with unique rock features. Gets crowded on the weekends. Arrive early for entry. It's not just one dome, but three. You can go off trail easily to explore. Do not climb the domes at night. There's a primitive campground behind the main dome near the lake. Don't carry too much when going to it since it requires scrambling. I camped in the main campground for car camping. Make reservations for that one well in advance.
