The Umqua River Lighthouse is the only lighthouse with a colored signal on the Oregon coast. The lighthouse sits on a hill 100 feet above sea level on the south side of Winchester Bay. Besides touring the lighthouse, you can camp here or rent a cabin or yurt and swim, canoe or fish at Lake Marie, a small freshwater lake trapped by the dunes.

The park is open all year. Reservations are advised for campsites, cabins and yurts and can be made 2 days to 9 months in advance.
