About Boundary Waters
The million-acre Boundary Waters Canoe Area Wilderness, paired with Ontario's adjoining Quetico Provincial Park, was designated an International Dark Sky Sanctuary in 2020 — one of the largest protected dark-sky areas on the continent. It's canoe-in wilderness, so the reward for the effort is about as dark as the Lower 48 gets.
What you can see in the sky
Milky Way, Andromeda Galaxy to the naked eye, and frequent aurora borealis during solar maximum.
Best time of year
Late summer and fall for clear, dry air; aurora is a real possibility on active nights at this latitude.
