Boulder Lake

Aerial view of Boulder Lake, a 516 acre lake in Boulder Junction, Wisconsin

Boulder Lake is the closest lake to downtown Boulder Junction, offering rare walkable proximity to shops and restaurants while still maintaining a true Northwoods feel. Its 516 acres include miles of wooded shoreline and a designated paddling route that highlights bays, channels, and forested edges.

The layout makes it versatile: owners can paddle quiet backwaters, cruise larger basins, or connect to nearby rivers and routes without leaving the immediate area. Despite its in-town location, it feels like a genuine Northwoods lake rather than an urban pond.

Buyers who choose Boulder Lake typically want convenience without sacrificing the look and feel of being “up north” once they leave the dock.
