Had to switch sites because of a rattlesnake den. EXACTLY what I wanted, frankly.
An excellent little campsite that is FOC and quiet. Make sure you proceed past other sites almost to the end and you'll be glad you did. Pack it in/pack it out at this site. Though we have a secure camper we do utilize bear canisters and rat sacks. There are toilets so no meed to dig (and the ground was cold so good thing). No water or electricity so you wind up meeting hard core enthusiasts who typically offer some awesome suggestions of things not online. We were blessed to receive some sight seeing tips and throughly enjoyed it. Bring plenty of water and TP if making a few nights of it. Boots stayed on all day and dry!
The entrance is very understated and underwhelming, you will pass a oil construction area as you enter the park. As you continue driving almost instantly notice the gorge. You will pass three day use areas all of which offer amazing views. Continue to drive until you reach the campground (which by the way is free) there are six campsites situated on the rim of the canyon. All campgrounds have picnic tables, some have covered picnic tables with fire rings. There are very well maintained trails that offer spectacular sights from all direction. There is vault toilets that are very clean, but no electricity, trash or water. So trash in, trash out.
