We spent seven days at the National Park camp ground. With our Golden Access card we paid $10 a night. We used our Generator and Solar for there are no hook ups. Boondocking is our chosen way of camping and this campground offered everything we require. The Rangers were friendly even when they confronted me for using a metal detector when I was trying to assist our neighbor locate a lost key. I was told that under no circumstances can a metal detector be used which I understand and quickly complied. We found the missing key and all was well. We will differently stay at this campground again. Maybe as soon as this fall.
