11 Best Sights in San Juan Island, The San Juan Islands

To watch whales cavorting in Haro Strait, head to these 36 acres on San Juan's western side just 9 miles from Friday Harbor. A rocky coastal trail leads to lookout points and a little 1919 lighthouse. The best time to spot whales is from the end of April through September, but resident pods of orcas regularly cruise past the point. This park is also a beautiful spot to soak in a summer sunset, with expansive views of Vancouver Island and beyond.

It's hard to believe that fashionable Roche Harbor at the northern end of San Juan Island was once the most important producer of builder's lime on the West Coast. In 1882, John S. McMillin gained control of the lime company and expanded production. But even in its heyday as a limestone quarrying village, Roche Harbor was known for abundant flowers and welcoming accommodations. McMillin's former home is now a restaurant, and workers' cottages have been transformed into comfortable visitors' lodgings. With its rose gardens, cobblestone waterfront, and well-manicured lawns, Roche Harbor retains the flavor of its days as a hangout for McMillin's powerful friends—especially since the sheltered harbor is very popular with well-to-do pleasure boaters.

Fortifications and other 19th-century military installments commemorate the Pig War, in which the United States and Great Britain nearly went into battle over their respective claims on the San Juan Islands. The park comprises two separate areas on opposite sides of the island. English Camp, in a sheltered cove of Garrison Bay on the northern end, includes a blockhouse, a commissary, and barracks. American Camp, on the southern end, has a visitor center and the remains of fortifications; it stretches along driftwood-strewn beaches. Great views greet you from the top of the Mt. Finlayson Trail—if you're lucky, you might be able to see Mt. Baker and Mt. Rainier along with the Olympics. From June to August you can take guided hikes and see reenactments of 1860s-era military life.

Kids and adults love admiring the 60 or so alpacas from South America at this sprawling 50-acre ranch on the west side of the island. The shop in the big barn displays beautiful, high-quality clothing and crafts, all handmade from alpaca hair.

A remodeled 1895 schoolhouse serving estate-grown wines, this picturesque winery is worth a visit for the scenery and its award-winning Siegerrebe and Madeleine Angevine varietals (the winery belongs to the Puget Sound AVA, the coolest-climate growing region in Washington).
