(Minnesota)
Afton State Park is a state park of Minnesota, USA, on the St. Croix River in Washington County. Its hiking trails offer views of the river, rolling glacial moraine, and bluffland it preserves. It is a popular place for birdwatching, picnics, camping, and other typical outdoor recreational activities. To deter overuse of a state park only 20 miles (32 km) from downtown St. Paul, there is no vehicle access to the camping area or swimming beach. (Ref: https://en.wikipedia.org/wiki/Afton_State_Park)
