The rocks and islands along Washington's outer coast provide vital habitat for nesting and migrating bird populations. These sentinels are home to some of the country's largest seabird breeding populations. In addition, marine mammals feed in the waters surrounding the islands and rest on the low crags. While there is a 200-yard buffer zone surrounding each island to protect sensitive wildlife, there are opportunities to view wildlife with binoculars or spotting scopes from watercraft and from several beaches along the coast, including Shi Shi, Cape Alava, Rialto, Second, Ruby, and Kalaloch.
