Penrose Point State Park
Lakebay, WA
Penrose Point State Park sits on Mayo Cove and Carr Inlet on the Key Peninsula, a 237-acre park that's genuinely one of the state's top shellfish beaches, enhanced with Manila clams and Pacific oysters alongside native littleneck, butter, horse, and softshell clams. It set a state harvest record in 2025 for the most clams dug of any Washington beach that year.
A genuinely record-setting shellfish beach, well documented and a real public park, hard to beat for anyone serious about clamming.
How we score beachesCheck current season dates before digging; the innermost part of Mayo Cove near the boat dock is closed to harvest year round, and season windows shift year to year.
