Boundary Waters Canoe Area planning
Boundary Waters Canoe Area wildlife & seasons
What lives here and what each season brings, so you time the trip for the experience you want.
Wildlife
Black bears, moose, timber wolves, bald eagles and common loons. Keep a clean camp and hang or canister your food — habituated bears get camps closed.
Season by season
| Season | Window | Conditions |
|---|---|---|
| Spring | Ice-out – mid-June | Ice-out typically lands in early May. Cold water, few bugs, and peak walleye and lake-trout fishing. |
| Summer | Mid-June – August | Warm and humid with the year's heaviest mosquito and black-fly pressure in June and July. |
| Autumn | September – October | Cool, bug-free days and peak color from late September. Cold nights and early frosts. |
| Winter | November – April | Deep snow and extreme cold — ski and dogsled country, not canoe season. |
Water conditions
Treat every drop from lakes and streams — boil at least one minute, filter, or purify chemically. Wind, not current, is the force that sets your schedule on the big lakes.
