User fees are required for all overnight visitors to the BWCAW between May 1 and September 30.
User Fees Per Person Per Trip
The purchase of a BWCAW Seasonal Fee Card fulfills the user fee requirements for the season, but does not eliminate the need for obtaining a BWCAW permit. For reserved permits, it does not eliminate the need to pay the $6.00 reservation fee and user fee deposit. Seasonal Fee Cards may be purchased in person after May 1 from any Forest Service office.
