Campers continue to flock to Kampgrounds of America (KOA) locations this summer.

The company reported in a press release that figures for the recent Fourth of July weekend show KOA camper nights up nearly 6% from the Fourth of July Weekend in 2014. Holiday results for the July 1 Canada Day Celebration at the 32 Canadian KOA parks were even more impressive, with a 25% increase in camper nights.

A camper night is measured as one campsite or cabin accommodation being occupied for one night, much the same as a room night is measured in the hotel industry.

KOA’s Care Camps Big Weekend event May 8-9 started the summer season’s strong performance, with an increase of 2% in camper nights. Canada’s Victoria Day Weekend on May 16-18 was up nearly 12% and Memorial Day Weekend showed a nearly 6% climb in camper nights compared to 2014.

Father’s Day Weekend at KOA was also strong, with camper nights up nearly 13% compared to the same weekend in 2014.

Year to date, short-term camper nights at KOA are up nearly 11% for the entire North American system. Advanced reservations for the remainder of the summer camping season are up about 10%.
