Olympic Coast National Marine Sanctuary is one of the nation's most treasured ocean areas, and home to a rich abundance of marine mammals, seabirds, fish, and thriving invertebrate communities.

The area occupies a maritime cultural landscape that has supported humans since time immemorial. The contemporary cultures of four coastal tribes - Hoh Tribe, Makah Tribe, Quileute Tribe, and Quinault Indian Nation - have forged inseparable ties to the ocean environment, maintaining traditions of the past while they navigate the challenges of the present.

Additionally, there are approximately two hundred historical shipwrecks reported in the vicinity of the sanctuary that mark the history of maritime shipping along the Olympic Coast.
