San Juan Islands Live Image
IslandCam.com provides 24 hour, live coverage of the San Juan Islands and beyond! Take advantage of the specials, news, weather, features, events, travel, discounts, and more.
FerryCam.net is provided in an effort to help better inform people traveling to and from the San Juan Islands and Sidney, B.C. via the Washington State Ferries. But remember, it is not a substitute for common sense and planning. We recommend getting your car in the ferry line one hour prior to departure during the fall, winter and spring, and two to three hours ahead during summer.
The San Juan Islands enjoy an average of 247 days with sunshine and about half the rainfall of Seattle, thanks to the "rain shadow" effect of the Olympic Mountains to the south. It's no wonder visitors are attracted to the islands year round!
