About San Juan Islands National Monument

Situated in the northern reaches of Washington State’s Puget Sound, the San Juan Islands are a uniquely beautiful archipelago of over 450 islands, rocks, and pinnacles. The new San Juan Islands National Monument (established Mar. 25, 2013) encompasses approximately 1,000 acres of land spread across many of these rocks and islands. It contains a wide array of habitats, with woodlands, grasslands, and wetlands intermixed with rocky balds, bluffs, inter-tidal areas, and sandy beaches. This diversity of habitats is critical to supporting an equally varied collection of wildlife, including black-tail deer, river otter, mink, and an array of birdlife such as the threatened marbled murrelet and the recently reintroduced western bluebird.
