Southwick Beach State Park

Southwick Beach State Park is a New York State park that lies along an unusual stretch of sandy beach on the eastern shore of Lake Ontario. The park is 464 acres (188 ha) in size with a 3,500 foot (1,100 m) length of beach, and is visited annually by about 100,000 people. Immediately to the south is the Lakeview Wildlife Management Area (3,461 acres (1,401 ha)), which extends the publicly accessible beach by several miles. They are in the Town of Ellisburg in Jefferson County, New York south of the lakeside community of Jefferson Park.

The park offers an extensive campground with tent and trailer sites, picnic facilities, playing fields and a playground. In summer, the swimming area has lifeguards and the park store is open. In winter, snowmobiles are permitted in the park. The park has an accessible nature trail. There are hiking trails from the park that extend into the Lakeview Wildlife Management Area. Lakeview itself has several access points for launching boats, as well as a second nature trail along South Sandy Creek. The hiking trails and boat routes are described at several websites, and in guidebooks by William P. Ehling and by Susan Peterson Gateley.

The park and wildlife management area lie within a rare, freshwater coastal barrier environment that consists of beaches, sand dunes, embayments and marshes. The wildlife management area is also the Lakeview Marsh and Barrier Beach National Natural Landmark, which was cited in 1973 as, "One of the best and most extensive marshlands that lie in protected bays and behind barrier beaches along eastern Lake Ontario." Southwick Beach State Park and Lakeview Wildlife Management Area are included as parts of a proposed New York State Natural Heritage Area entitled "Eastern Lake Ontario Barrier Beach and Wetland Complex".
