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. Step onto horseshoe-shaped Orcas Island, and drink in the green paradise the locals call “the emerald isle” and “the gem of the San Juans” -- a happy combination of stunning shoreline, the highest mountain in the islands, and a handful of charming hamlets. Orcas Island is an ideal Northwest escape for those who love nature, outdoor activities and cultural attractions. From kayaking and whale watching on Puget Sound to touring artisans’ studios, enjoying the wide array of activities will help create an unforgettable experience in one of the world’s most beautiful locations.
