Attention: West Loop area (sites 40-73) will be closed to reservations through June 19th. Walk-in camping will be allowed at 2 day intervals. This closure is due to planned park improvement that is scheduled to take place between May 1st and June 19th. It will take 1 to 2 weeks to complete and the West Loop will be closed to all camping during this time. All other camping and day use areas will be unaffected. Additional information will be provided as it becomes available. Thank you for your patience during this time. For more information please contact the park staff at 608-648-3314.
