Inside Willow River State Park

Whether you’re hoping to enjoy hiking, boating, fishing, rock climbing, swimming or more – there’s certainly something for every type of traveler at Willow River State Park.


Hiking : The park contains 13 miles of trails for hiking, including one which is ADA accessible (the Hidden Ponds Nature Trail – a paved loop around a wetland). Other popular trails include the Little Falls Trail, Willow Falls Trail, and Pioneer Trail.

Boating : Temporarily, boating, canoeing and kayaking is impacted due to the drawdown of Little Falls Lake. As a result, canoe and kayak rentals are unavailable for the time being. Kayaking opportunities are still available in the river, however.

Fishing : The Willow River is stocked with trout and fishing is available both above and below the lakebed. It’s recommended that trout fishing is best upstream of the waterfall.

Rock climbing : There are several bolted sport climbs on the gorge walls, ranging from 5.9 to 5.14c in difficulty. Keep in mind no climbing is allowed on Saturday or after noon on Friday or Sunday. Leaving fixed gear is prohibited, as is rappelling from the top of the gorge.

Swimming : Due to the drawdown of Little Falls Lake, the swimming beach is temporarily unavailable. When the lake returns to its normal state, however, the swimming beach serves as the only designated swimming area within the park. Picnic tables, a beach house, and extensive parking are available here.

Winter activities : The park has 9 miles of cross-country ski trails on the south side of the river, as well as 2 miles of hard packed trails on the north side of the river available for snowshoeing and dog sledding. Other winter activities include sledding and ice fishing.
