At Casini Ranch in Duncans Mills, the Russian River bends past a mile of riverbank walled in by redwoods and steep hills. Most mornings start down at that bend, and the ranch's ducks and goats keep the kids busy between trips to the water. The day out is Jenner, a short drive west, where the river meets the Pacific and seals haul out on the beach at the mouth.
That rhythm is what makes the river a good base for a rig. You set up once, leave the awning out, and do the coast as day trips instead of breaking camp every morning. Jenner is also where Highway 1 turns north, so the second half of the week can move up the coast without doubling back through town.
Casini takes RVs of any length on 50-amp and 30-amp sites, from dry pads up to platinum sites with full hookups, as of September 2026. A family parked on the bank for the week will want the full-hookup end of that range. Book the riverside site before the motorhome, and for a summer week, book it early.
If the river reservation starts the next morning, Spring Lake Regional Park in town makes an easy first night beside the lake. Spring Lake caps RVs at 31 feet, and the county lists no electric hookups there but a dump station for registered campers.
Armstrong Redwoods and the Bodega Dunes overnight are near enough for a day off the river, and the Sonoma campervan page covers both, along with Sugarloaf Ridge. Wine country east of town, the Napa side and Lake Berryessa, is the week on the Sonoma RV page.
Stillwater Cove and Salt Point, up Highway 1 from Jenner
North of Jenner the Sonoma Coast gets quieter, with Highway 1 running above coves and rocky headlands. Stillwater Cove Regional Park is the night to aim for, with a small crescent beach at the bottom of the cove and the campground set back inland in a redwood canyon, where the Canyon Trail winds down through the trees. Salt Point State Park, just north, is headland country, the kind of coast you take in from one pull-off after another: park the rig, walk out on the rock, move on.
Stillwater caps RVs at 31 feet and has electric hookups at sites 3 through 5 and 8 through 10 only, and those are the only electric hookups in the county park system. Plan the tanks around the river, leaving Casini empty from a full-hookup site and using Stillwater's dump station before heading back inland. Salt Point's page asks you to call about trailer and motorhome size as of September 2026, so ring the park with your rig's length in hand before you book.
Farther up the coast, Gualala Point Regional Park looks over the Gualala River's estuary where it bends in behind the surf line. The county limits RVs there to 24 feet, which keeps a 30-footer at Stillwater. Couples, or anyone who would rather have Gualala's river bend than the extra beds, can size down with a shorter rig from the California campervan listings.
