Roche Harbor Marina
Roche Harbor Marina sits on the northwest tip of San Juan Island, steeped in history with a 19th-century lime works company town backdrop that makes it unlike any other marina in the Pacific Northwest. You'll find 425 slips accommodating vessels up to 2,000 feet, with year-round moorage options, 30/50 amp power, water hook-ups, and mobile pump-out service. The historic Hotel de Haro, sculpted gardens, and a vibrant waterfront village with restaurants and shops are steps from your slip, so there's plenty to explore beyond the dock.
