Filucy Bay, located near Longbranch on the Key Peninsula in Washington, is a serene and protected tidal estuary. It offers a tranquil environment with a rich variety of wildlife, including mother bears, osprey, and great blue herons. The bay is known for its warm waters and an oyster farm in the northern arm. The area is also famous for its sand dollars, which are abundant in the bay. Filucy Bay has a historical significance, having been a favorite fishing spot for First Nations Peoples and now a site of interest for archeologists.
The bay is surrounded by mature forests of fir, cedar, maple, and alder, making it a haven for nature lovers. The Filucy Bay Preserve, managed by the Great Peninsula Conservancy, protects over a mile of shoreline and provides a water-landing site accessible by hand-powered watercraft.
Visitors can enjoy the peaceful atmosphere and explore the bay's natural beauty, though it remains relatively unimproved and off the beaten path.
