Nice family centric campground on Dorena Lake
The Baker Bay Campground and Marina is a county park outside of Cottage Grove, Oregon. It has a boat launch and boat rentals. There are several huge inflatable water structures in the bay which kids can play on for a fee. The concession stand is currently under construction however there is plenty of green space for picnics. There is a large play structure, horseshoes, and a sand volleyball pit.
Great site for families with kids.
Decent main restroom and showers however, the vault toilet near the main camping spots was the WORST I have ever been near. I can't imagine how people near the toilet could stand being there - especially in the heat of the summer.
