Just past a random industrial and office park area and right on the river, Wentachee Confluence State Park is a very large, flat, grassy area with plenty of room but very little privacy between sites.

Bathrooms are clean if older. Lots and lots of green grass (often covered by Canadian Goose poop). Sprinklers are on a schedule timer (certain days), which means that tents can't go on the grass. Some sites had lovely water views. There's extra parking available as well as several pull-throughs. All-in-all, the campground was nice and felt safe, but not that exciting.

The day use area, however, was pretty great and just a short walk from the campground. It included a boat ramp, seating on the river, tennis courts, picnic tables, and a very nice play structure. I have no doubt this place gets busy in the summer, though when we were there in March is was well used already and the campground was probably 70% full.

Tip: Great place for kids to ride bikes with plenty of paved pathways between the campground and day use area.
