Straight Lake State Park is a 2,780-acre Wisconsin state park north of Luck, established in 2002 to protect the landscape around Straight Lake and the Straight River. The Ice Age National Scenic Trail crosses the park along the lake’s northern shore and then follows the Straight River through the Straight River Tunnel Channel. The park is also crossed by the Clam Falls Trail, an abandoned road that was once an important route during the logging era and now roughly parallels the Ice Age Trail.
