It is in Clallam County, Washington, where the Strait of Juan de Fuca empties into the Pacific Ocean. It is also part of the Makah Reservation, and is the northern boundary of the Olympic Coast National Marine Sanctuary. Cape Flattery can be reached from a short hike, most of which is boardwalked. The westernmost point in the contiguous United States is at Cape Alava, south of Cape Flattery in Olympic National Park. However, the westernmost tip of Cape Flattery is almost exactly as far west as Cape Alava.
