The park is near the southern end of a notable 17-mile (27 km) length of sandy shoreline, coastal dunes, and wetlands (the Eastern Lake Ontario Dunes and Wetlands); a 1959 study noted that "The eastern end of Lake Ontario contains not only the finest beaches on the entire lake, but also the finest wildlife habitat."
