The sites are small and first come first serve but if you are lucky you can get a spot that backs onto the river. It is a beautiful area but if you don't get by the river it is just a rv park. There were also slugs everywhere. There are 2 small towns around and about 40 min to Seattle.
The cost is not $16.00. It's $45 a nite for rv and a very nice park.
The campground doesn't appear to be well maintained and it's very expensive for what you get. We paid for 50 amp site and the 50 amp plug had been ripped out. But it's hard to find TV parks in the Seattle area.
