No fee in off season, but is limited to 3 tent sites and 2 RV pads near the entrance. Surprisingly quiet considering the proximity to the road. Toilet was clean and unlocked. We decided to try and boondock somewhere near Custer and visit on our way home since we love this area so much. Just happened to spot this in the national Forest. Good thing, because we went for a walk at Sylvan Lake later on and I decided it was so beautiful, that would be the place I'd pop the question, right on those rocks. I carried that ring around for a week straight...

She said "yes." :)
