River bank

Sitting on four acres along the Cowlitz River outside campgrounds around Castle Rock, River Bank has the feel of a private riverside property more than a conventional campground. The setup is open and informal: campers park on grass near the river bank, with no assigned spots or hookups. Self-containment is required. The owners have a reputation for flexibility about where rigs park, and reviewers consistently describe the hosts as accommodating and welcoming.

Water access is central to the experience here. Anglers come specifically for salmon and steelhead fishing on the Cowlitz, and the riverfront also works for swimming and boating. Steve B. sums up the draw simply: "You park down by the river and enjoy the quiet and beautiful spot." Cell coverage is solid, with one camper reporting three bars of 5G on Verizon. The campground sits just minutes off the interstate, though reviewers note it reads more rural than that proximity suggests.

A few practical notes: the facility is still developing, so expect basic amenities rather than a full-service setup. Reservations are available, and at $30 per night, the site draws repeat visitors. Campers with larger rigs should call ahead to confirm fit, as the property is not suited to all rig sizes. Nearby options like Cedars RV Park and Mt. St. Helens RV Park provide alternatives with hookups if self-containment isn't an option. Book early during summer fishing season, when river access sites in this corridor fill quickly.
