Quick single night trip out during the week in mid September. 

I ended up staying at a dispersed spot on the way in.. I noticed it on my way to the campground and after circling the tent sites I decided to give it a shot. One of the best spots I've ever camped in. If you're cool with no/a short drive to the vault toilets then I'd recommend grabbing this spot if you see it open. It's before the giant hill with the offroad track going up it, 3 or so spots back. It's tucked down between the road and one of the creeks. Plenty of room for a couple cars, tents and hammocks. 

There's a small walkway down to the creek right in the campsite. The primo secret is that there is a short (5-10 yards) trail behind the campsite leading to a great wading spot in the river. The water was low while I was visiting so I lugged some supplies out onto some rocks in the middle of the creek to brew the morning coffee and cook breakfast. 

You can easily wade downstream the river to a fairly wide and deep swimming hole with a great rock outcropping.

**For anyone worried about the drive - I made it in a 2dr civic sport coupe. The pothole dodging was actually fun - it's rough but definitely not as bad as some earlier reviews make out

Beware of landslides - there are at least two points on the gravel road to the campground that have recently been repaired.**
