Potato Creek State Park is an Indiana state park located in north central part of the U.S. state of Indiana about 12 miles (19 km) southwest of South Bend. One of the newest, yet the third most-visited of the state park system (behind only Brown County State Park and Indiana Dunes State Park), it is open year-round and supports various activities and facilities, including fishing, hiking, camping and mountain biking. Natural habitats include the 327 acre (1.3 km²) Worster Lake, old fields, mature woodlands, restored prairies, and diverse restored wetlands. Each offers different opportunities for plant and wildlife observation. The northeast corner has been designated "Swamp Rose Nature Preserve"; now about 1 square mile is either wetlands or in Worster Lake.
