These five islands off the Southern California coast comprise one of America’s most undeveloped—and utterly magical—national parks. Revered for its endemic plants and plentiful wildlife, the “Galapagos of North America” has no lodgings, stores, or restaurants—only a wild coastal landscape and come-hither scenery. At this ocean-bound preserve, the action centers around hiking, camping, wildlife-watching, and the chance to totally and completely unplug.
