A little background on BWCA Permit Availability
The Boundary Water Canoe Area Wilderness (BWCAW or BWCA) is a federally designated wilderness preserve. Joined by the Quetico Provincial Park, the boundary water area has 2.3 million acres and 1600 lakes of pristine non-motorized wilderness that is primarily accessed by canoes. On the U.S. side alone there are 2,200 designated campsites that are used by people that go on multiple day trips. The U.S. Forest Service regulates the number of people who enter the BWCA by issuing permits. There are designated entry points all around the edge of the BWCA and each day a designated amount of permits are allotted to each entry point. BWCA permit availability is based off of each individual area.
These permits must be gained in advance to guarantee availability. Getting a permit is a critical step in planning your BWCA canoe trip.
