Camping here was free when we went, you just had to reserve a site using a little tag. We stayed for 2 nights. There were toilets and running water, so we filled up our 5 gallon jug. It was great to stay for free in the NP so we could spend the whole day at the park. There were picnic tables and tons of trees for shade and hammocks. There were also tent pads. When we were there (May) there were tons of open sites, I think we were 1 of 4 people staying there. Nice and quiet!
