Stonefield Beach State Recreation Site features small gravel parking areas just north and south of the bridge at Tenmile Creek near milepost 171 on US 101, south of Cape Perpetua on the Oregon coast. There are no rest rooms or cell phone service.
The shore at Stonefield Beach is a sandy beach, with persistent beds of 5-inch rocks along the upper reaches. It's reached by short sandy trails from the parking areas.
