Salt River Bay National Historic Park and Ecological Preserve

Salt River Bay National Historic Park and Ecological Preserve is a unit of the National Park Service on the island of St. Croix in the U.S. Virgin Islands. It preserves upland watersheds, mangrove forests, and estuarine and marine environments that support threatened and endangered species. It also contains the Columbus Landing Site, a National Historic Landmark that is the only known site where members of a Columbus expedition set foot on what is now United States territory. The site is marked by Fort Salé, a remaining earthworks fortification from the French period of occupation, about 1617. The park also preserves prehistoric and colonial-era archeological sites including the only existing example of a ball court in the US Virgin Islands.
