The Wilderness holds Minnesota's westernmost stand of black spruce-tamarack forest and two boggy lakes, Kuriko and Whiskey, neither of which support fish. Whiskey Lake Trail leads about two miles into Whiskey Lake, but no camping is allowed. Two primitive campgrounds are adjacent to Agassiz. Agassiz Wilderness lies within the 61,449-acre Agassiz National Wildlife Refuge, an area primarily protected for waterfowl production and maintenance. Originally named Mud Lake Refuge, almost one-sixth of the area is under water and more than 40,000 acres are wetland dominated by cattail.
Ducks abound in migratory seasons.
Moose and white-tailed deer bring hunters. Spring and fall are most suitable to observe the wildlife. Free permit required for photographers.
