Forested Puget Sound marine park on the Key Peninsula with ~82 campsites (no hookups, 35 ft max), 2 miles of hiking trails, and saltwater coves.
Penrose Point is a 237-acre marine park on the southern Key Peninsula with nearly 2 miles of Puget Sound shoreline and 2.5 miles of old-growth forest trails. About 82 RV-friendly sites have no hookups but access three central bathhouses, a dump station, potable water, and fire pits. The park's two sheltered coves — one saltwater, one freshwater — offer calm kayaking and swimming. Joemma Beach State Park is just 5 miles south via boat for a full-day paddle destination.
Penrose Point State Park occupies a forested point jutting into Mayo Cove on southern Puget Sound, protecting one of the most pristine small bays remaining in the Puget Sound basin. The park's 1.5 miles of shoreline ranges from rocky intertidal zones to protected sandy coves, creating a mosaic of marine habitat types that supports exceptional diversity of shorebirds, waterfowl, and marine mammals. Mayo Cove's protected waters serve as an informal marine reserve, with little powerboat traffic allowing kelp beds, eelgrass, and juvenile fish populations to thrive at levels rarely seen in accessible southern Puget Sound.

Driftwood Loop sites closest to the beach fill first and offer the best tidal flat access — excellent for shellfish harvesting at low tide. Maple Loop sites are shadier, more private, and better for hot summer days. Sites 14–30 are the most level for RVs. The long waterfront walkway makes this a great evening stroll park. The shallow bay in front of camp drains significantly at low tide — worth checking tide charts.
