San Juan Islands, Washington USA. Travel and Tourism. Vacation Packages. The waters of the Pacific Northwest’s Salish Sea, between mainland Washington and Vancouver Island, contain hundreds of islands, some little more than rocky reefs, others rising to nearly 2,500 feet. Among these, the San Juans are considered by many to be the loveliest. About 100 miles northwest of Seattle, these romantic islands abound with breathtaking rolling pastures, rocky shorelines, and thickly forested ridges, and their quaint villages draw art lovers, foodies, and city folk seeking serenity. Inns are easygoing and well-appointed, and many restaurants are helmed by highly talented chefs emphasizing local ingredients. Each of the San Juans maintains a distinct character, though all share in the archipelago's blessings of serene farmlands, unspoiled coves, blue-green or gray tidal waters, and radiant light. Offshore, seals haul out on sandbanks and orcas patrol the deep channels. You may see the occasional minke whale frolicking in the kelp, and humpback whales have become increasingly visible around the islands. You'll very rarely spy gray whales, which stick closer Washington's mainland. There are 172 named islands in the archipelago. Sixty are populated (though most have only a house or two), and 10 are state marine parks, some of which are accessible only to nonmotorized craft kayakers, canoes, small sailboats—navigating the Cascadia Marine Trail. The San Juan Islands have valleys and mountains where eagles soar, and forests and leafy glens where the small island deer browse. Even a species of prickly pear cactus (Opuntia fragilis) grows here. Beaches can be of sand or shingle (covered in small pebbles). The islands are home to ducks and swans, herons and hawks, otters and whales. The main draw is the great outdoors, but there's plenty to do once you've seen the whales or hiked. Each island, even tiny Lopez, has at least one commercial center, where you'll find shops, restaurants, and history museums. Not surprisingly, many artists take inspiration from the dramatic surroundings, and each island has a collection of galleries; Friday Harbor even has an impressive sculpture park and art museum. Lavender and alpaca farms, spas and yoga studios, a whale museum and lighthouse tours the San Juans have a little bit of everything.
