North Dakota’s homesteading spirit is evident at Icelandic State Park, located on the shores of Lake Renwick. Established in 1964, this 912-acre park allows visitors to learn about the state’s early settlement and provides an array of recreational opportunities. Boating, swimming, and fishing are a few favorite summer activities while snowshoeing and cross-country skiing are popular during the winter. Picnic areas enable visitors to enjoy a relaxing afternoon in the shade of old oak trees.
