Discovery Park is a 534-acre (2.16 km2) park on the shores of Puget Sound in the Magnolia neighborhood of Seattle, Washington. It is the city's largest public park and contains 11.81 miles (19.01 km) of walking trails. United Indians of All Tribes' Daybreak Star Cultural Center is within the park's boundaries. A lighthouse is located on West Point, the westernmost point of the park and the entire city of Seattle, and on the south side of the North Beach strip is a sewage treatment plant, but it is almost entirely concealed from the marsh, beach, and trail. The Discovery Park Loop Trail, designated a National Recreation Trail in 1975, runs 2.8 miles (4.5 km) through the park, connecting to other trails.
