I always like to hike down and see this old cabin foundation and chimney. It's right across the river from where the river tour boats land on the MN side.

Probably one of the most highly trafficked of the Minnesota's State Parks. Worth at least the short walk around the potholes, and check out more of the park or the Wisconsin side which is much bigger.

Milltown makes a great pit stop if you're hiking through Polk County. The small-town centre has a handful of places to refuel, whether you're in the mood for a slice of pizza, a strong cup of coffee, or a hearty pub meal. Just a short drive away, Balsam Lake Brewery & Market is worth checking out—especially if you’re after local produce, baked goods, or craft beer.
