Minnesotans, after a year cooped up inside, flock to state parks and campgrounds Campsite occupancy rates and annual state park permit sales are up. Author: A year of cabin fever has people flocking to Minnesota State Parks and campsites. Through the first six months of 2021, nearly one-third of all available nights at state campsites had been reserved for use, according to data provided by the Minnesota DNR. During that timeframe the agency recorded 142,095 reservations out of 431,725 available nights. This occupancy rate of 32.91% marks a fairly large jump from 2019, when the occupancy rate from January through June was 24.49% (103,368 visits during 422,104 available nights). In May alone this year, more than half of all available campsite nights were taken up.
