Reservations, modifications and cancelations

Reservations, modifications and cancellations

  • Visit MiDNRReservations.com or call 1-800-447-2757 to make a reservation. Sites are also available on a first-come, first-served basis.

    • Campsites and harbor slips can be reserved 6 months in advance (at the times below).
    • Overnight lodging (cabins, yurts, lodges and shelters) can be reserved 1 year in advance (at the times below).

    When the booking window opens, inventory becomes available Monday through Friday at 8 a.m. and Saturday and Sunday at 9 a.m.

  • Reducing the number of nights after a camp is established at the park

    Once checked in at the park, if you choose to reduce the length of your stay a refund will be calculated as a percentage of unused camp night fees based on the number of months the reservation has been held (see sliding modification/cancellation formula below).

    If you check out before 1 p.m., that night’s camp fees will be included in the refund formula. If you check out after 1 p.m., that night’s camp fees will NOT be included in the refund formula.

    Modification and cancellation policy

    You may cancel or modify your camping reservation online at MiDNRReservations.com or by calling 800-447-2757. Please note that the original nonrefundable reservation fee, a cancellation fee and a reduced-stay fee will be assessed.

    Once campsite reservations are made, they cannot be canceled or modified more than five months before the arrival date.

    The following fees will be assessed if you cancel or modify your camping reservation:

    1. Nonrefundable reservation fee (paid at the time a reservation is booked): $8 for reservations made online and $10 for reservations made through the call center.
    2. $10 cancellation/modification fee.
    3. Reduced-stay fee (an incremental fee determined by the length of time a reservation is held and the number of eligible nights canceled); see sliding modification/cancellation formula below.
      1. If canceled or modified before the arrival date, all unused camp nights are eligible for the reduced-stay fee according to the sliding modification/cancellation formula.
      2. If canceled on the day of arrival or later, the first night’s fee and the cost of any nights that have already passed will be charged at the full rate. Any remaining unused nights are eligible for a refund using the sliding modification/cancellation formula.

    Reservations that are canceled on the same day the reservation was created will be assessed the $10 cancellation/modification fee only.

    Modifications to reservations that do not affect the length of stay will be assessed the $10 cancellation/modification fee only.

    Modifications to reservations that result in an increase in the length of stay will be assessed the additional nights’ fees only and NOT the $10 cancellation/modification fee.

    Reservations are held until 3 p.m. two days after the scheduled arrival date. Failure to check in within 48 hours of the check-in time will result in a “no-show” status and will incur the loss of two nights' fees plus the reduced-stay fee (assessed on remaining unused nights using the sliding modification/cancellation formula).
