Very nice tent portion of the campground, short walk to the beach, beach is very long and uncrowded, although they allow driving on it.
RV spots with hookups are lined up next to each other, very little space between.
Nice to have full hookups but we opted for a tent spot with our camper.
Separated tent and RV sites, sites are spacious, a very pretty and clean lake, Beer Garden at the lake, clean bathrooms, shower requires tokens but shortens the shower time if you have to wait.
We had a large group of four families and it accommodated us very well.
This was our second time staying there and was not disappointed.
Easy access, not far from I-5
Cougar is at the base of Mt St Helens on Yale Reservoir on the Lewis River. Tent only sites so keeps the big guys out. Every time we have been there it has been quiet and beautiful. The lake is big and very accessible. Take your mountain bikes and head to St Helens for tough but amazing rides.
