We offer the best and most successful whale watch experience in Northwest Washington. Our 110-foot P/V Island Caper provides heated indoor seating and outside rail space for every passenger. You’ll explore Washington’s beautiful San Juan Islands up close, learn local folklore and interesting facts from our onboard naturalist, enjoy breathtaking scenery and see a variety of whales, porpoises, seals, sea lions, raptors and sea birds. Join us for a daylong whale watch cruise and discover why the San Juan Islands and the Orca whales are considered natural treasures of the Pacific Northwest. If you’d prefer a more private adventure, Island Mariner Cruises can create a specific charter cruise for you and your clients, employees, wedding party, or family and friends.
