If you don’t have much camping gear, or just like a roof over your head, nearly half Minnesota’s state parks have camper cabins — rustic 12-by-16 structures with bunk beds, mattresses, a table and benches. About 90 cabins are available for rent throughout the park system, some with heating that are open year-round, others without heat that are available only in warmer months. All offer picnic tables and fire rings, and most, but not all, have electricity and screen porches. Restrooms or vault toilets are near each cabin. The cabins have proved popular, especially on weekends, so book early.
