Few towns are as aptly named as Watertown, the state’s fifth-largest city by population. Located in northeastern South Dakota at the heart of the prairie lands, Watertown sits along the Big Sioux River between Pelican Lake and Lake Kampeska. Just about anywhere you drive around Watertown, you’ll hit a lake soon enough. Head down to Oakwood Lakes State Park to swim, paddle, and sail around the eight glacial lakes, or visit nearby Lake Poinsett to camp or rent a cabin near the sandy beach. Bring your fishing rod, as this is the state’s walleye hotspot—you can even enjoy ice fishing through the winter months. It’s no surprise that Watertown’s best camping comes with a view of the water, whether you check into an RV park with full hookups in town, snag a spot at a state park campground, or set up camp at a tranquil lakeside Hipcamp.
