One of the things we like to do in the areas we visit is research and (hopefully) find areas we can take the AWD Van off pavement. The Oregon Coast is full of places to explore off road. Most roads are also utilized by logging companies but with a bit of pre planning your trip can include some enjoyable driving. Things to bring along are a CB radio as most entrances to these roads will have info posted on a tree as to what channel the truckers are utilizing and suggesting any motorist to monitor. We've learned that calling out our vehicle's description over the radio at the posted mile markers is proper travel-Etiquette.
OK, so if you want to have some fun exploring off pavement...
Travel from the campground south on 101 about 5 miles to HWY 53 and go inland and put into your GPS "Cook Creek Road". You will travel about 2 miles on HWY 53 and then take a couple roads (~1 to 2 miles on each road Miami Rd and Foss Rd) and come to Cook Creek Road. You should see a placard that has a map of the road you are on stating there are (free) dispersed camp sites. There are 17 of these sites located on Cook Creek Road and most of them are located next to the river. We visited each site and most were doable with TV + small trailers.
If planning a trip to the area with some dispersed camping in mind you might want to take a day trip to scout out which site you would like and make sure the road is all clear. It's a narrow road and not many places to make a U turn with trailer until you get to the camp sites (again most you can make U turns or are pull through).

Enjoy the area, and be safe always remembering these roads are work-home to BIG RIGS...we had to scoot the van to the very extreme edge of the roadway to let a loaded gravel truck get by. But the driver was polite and slowed down and scooted over also
