Keewaydin State Park is on the St. Lawrence River, offering excellent boating, fishing and, during the winter, ice fishing and cross-country skiing. The sheltered marina provides dock space for seasonal and transient visitors. Overlooking the river are 48 campsites. The park's terrain includes steep, rocky outcroppings between the campsites and the shoreline, providing vantage points for watching the ocean-going vessels traversing the river. The park also has a swimming pool and picnic areas.
