Duvall Beach is the strip of sand at the north end of McCormick Park, the City of Duvall's riverfront park on the east bank of the Snoqualmie River, downhill and a couple of blocks west of Main Street. The name is local, not official. Duvall's published parks map lists the site only as McCormick Park, and the city's own water safety handout calls it the beach at McCormick Park. OpenStreetMap carries the Duvall Beach label, and that is what people in town say, so both names point at the same sand.

The park address is 26200 NE Burhen Way and posted hours are dawn to dusk. Nothing here costs money. There is no admission charge, no parking fee, and no reservation needed for ordinary use. The lot is shared with the Duvall Police Department next door, which is one reason overnight camping never took hold. Gatherings of 30 people or fewer can simply turn up. Anything from 31 people up needs a Special Event Permit from the city.

For a small town park it is well equipped. Grass fields run back from the water, with picnic tables and benches spread along the shoreline, a grill, covered picnic shelters, a natural grass play area, and paths built to ADA access. A footbridge crosses the Coe-Clemons Creek wetland behind the developed area. The city lists portable restrooms, and there is also a wheelchair accessible toilet building and an unsupervised cold-water rinse shower a couple of minutes from the sand. Dogs are welcome on leash. A life jacket loaner station stands near the beach access.

The Snoqualmie Valley Trail runs along the back of the park and its Duvall trailhead is right here, so the beach is reachable on foot or by bike from town without touching a road. Paddlers work this reach as well. Taylor Landing and its boat launch sit about a quarter mile upstream, and when the river is low you can walk the shoreline between the two. A sandbar builds along this bank as the river drops through the summer, which is what turns the spot into a place families bring small children rather than a bank you scramble down.

Swimming season runs roughly late June into September. The Snoqualmie drains 645 square miles above the Duvall gauge, so it answers rain and mountain snowmelt quickly, and water that looks inviting in May is still cold and pushy. Late July through early September is when levels drop, the sandbar widens, and the river warms enough to stay in. Winter is another river altogether. Duvall floods, sometimes severely, and the river gauge at Duvall is worth checking before any shoulder season trip.

The hazard is real and the city states it plainly: there are no lifeguards at the beach at McCormick Park. Duvall has installed two life ring stations in the park for civilian use, to be thrown to a swimmer in trouble, and the city asks that both rings go in at once and that someone call 911. The Snoqualmie carries a drowning record. King County counts the Snoqualmie and the Green together for 17 percent of the 74 preventable open water drowning deaths in its review, and logged 25 preventable drowning deaths across the county in 2025. The December 2025 flooding pushed logs, rocks and other debris into the channel and shifted the riverbed, leaving pools deeper or shallower than they were and obstacles that give no sign above the surface. Wade the entry and feel the bottom before anyone jumps in. Keep a hand on small children, put a life jacket on anyone planning to float, and treat calm looking water over a moving river bed as exactly that.
