Swartswood State Park offers a boat launch on Swartswood Lake, a 519-acre natural glacial lake where only electric motors are permitted, making it ideal for kayaking, canoeing, and sailing.

The park features multiple access points including a canoe launch and boat launch near the campground, with amenities such as restrooms, showers, and a food concession stand (seasonal).

Additional water access is available at Little Swartswood Lake, located just minutes away by car or short hike from the main lake.
