This was our third consecutive year staying at Fox Camp. Our kids (four and eight) love this spot. There's plenty of room for them to run and play. Particular favorites are the buoy swing and taking out the paddle boat. As adults, we enjoy the tranquility of the campground and how well-kept it is.
Other bonuses include wildlife (garter snakes, frogs, rabbits, hawks, bats, deer), a park nearby (Donovan Park), and proximity to Sedro-Woolley. There may be other shopping and parks nearby, but there's another park in Sedro-Woolley (Pat's Park) and a Food Pavillion.
Larry is a fantastic host. He's easily accessible via text message and very responsive.
If you're looking for a quiet, peaceful getaway, I'd highly recommend this site. Side note: we are located near Lynnwood, and have found that it's best to take Highway 9 both north and south. The travel time on I-5 can vary widely, especially if there are slowdowns near Marysville and Everett. Additionally, the drive on Highway 9 is far more scenic.
