Straight Lake State Park

Straight Lake State Park offers a variety of recreation opportunities. In addition, the state park is adjacent to the state wildlife area, providing nearly 3,500 contiguous acres at Straight Lake.


Camping at Straight Lake

Canoeing and kayaking

Canoes, kayaks and other non-motorized watercraft can be carried from the parking areas to the lakes. The carry-in boat launch for Rainbow Lake is a short, 100-yard hike. The east carry-in boat launch on Straight Lake is 300 yards from the parking lot. The west carry-in boat launch on Straight Lake is 750 yards from the campground parking lot. Courtesy boat/canoe/kayak dollies are available at the campground and picnic area lots.

Canoes, kayaks and rowboats are not allowed to be left at the boat launches overnight.


Straight Lake is fed and drained by the Straight River. It is a premier northern wild lake with a great fishery of bass, northern pike and panfish. Boats may be carried in to fish.

Rainbow Lake is stocked every year with rainbow trout. Trout may be harvested from the first Saturday in May to the first Sunday in March. An accessible fishing platform is located on Rainbow Lake, next to the carry-in boat launch.

A fishing license is required for anyone age 16 or over. See fishing regulations.


The park is open to the public for foot traffic only. No motorized vehicles, bikes or horses are allowed. The Ice Age National Scenic Trail winds through the middle of the park along the Straight River and Straight Lake. There are about 8.5 miles of trail at the park.
