New Marina Now Open!
A visit to Rosario Resort is a must when planning a boating adventure in the San Juan Islands. The Rosario Marina is located on tranquil Cascade Bay halfway up East Sound's eastern shore on Orcas Island. The distant grandeur of the historic Moran Mansion guides boaters to Rosario as they enter East Sound. The marina offers over 30 slips, eight mooring buoys, safe anchorage and a warm welcome.
