Quiet.
This place is absolutely beautiful and would be perfect if it weren't for people leaving so much trash behind. My wife and I spent a lot of time picking up countless bullet casing and other trash. We heard numerous birds in the area, such as killdeer, mourning doves and owls. We saw a few small bunnies, not sure of the kind. There's a lot of dispersed camping. We saw RVs, Vans and a few tents. It was very quiet and people usually only stayed a few nights. We were here for 9 days. The hot springs are off the road across the street from the sign. It was a little too hot for my liking but my wife enjoyed wading in it.
