Sunset Bay State Park is a state park in the U.S. state of Oregon. Administered by the Oregon Parks and Recreation Department, it is about 0.4mi south of Cape Arago Lighthouse and 2.5mi outside the town of Charleston on Coos Bay. The park offers a crescent shaped beach, tide pools, hiking trails and a year-round campground.The park is one of three along the Cape Arago Highway, which runs along the Pacific Ocean west of U.S. Route 101. Sunset Bay State Park is about 1mi north of Shore Acres State Park and about 2mi north of Cape Arago State Park. A hiking trail links Sunset Bay to Shore Acres.Land for the park was acquired in stages through 1984. Coos County donated the original tract to the state in 1948. In 1954, Ralph Barker donated a parcel with a water supply. The Bureau of Land Management later added tracts through a grant to the state, which also bought, exchanged, or otherwise acquired land from private owners. The combined size of the parcels is about 405acre.
