Hartford Beach is located on the southern shoreline of Big Stone Lake and offers a small network of trails for hikers and bikers to enjoy when visiting the park. The Robar trail is located north of the campground and connects to the Aspen Spring trail. There are interpretive signs along the trail providing history about the natural terrain and history of the area. There is a gradual descent as the trail leads down towards the lake but the hike is otherwise short and easy to follow making it a good choice for all skill levels.
