The pristine waters that shape the state border may define the St. Croix National Scenic Riverway, but the area offers recreation to more than just paddlers. A new book describes more than 70 hiking trails along the riverway, with an emphasis on trails that are perfect for families with children. The book, Hittin’ the Trail: Day Hiking the St. Croix National Scenic Riverway, is the sixth hiking guidebook by western Wisconsin resident and Menomonie native Rob Bignell, and the first to be available as a paperback. (The others were published as e-books.) Published in early April, the book offers driving and parking directions; tells you how to find trailheads; describes the courses the trails take; and outlines flora, fauna, and scenic points you can see along the way. “In the scenic riverway, you can lean against 200-year-old trees or feel the splash of a hidden waterfall, you can retrace the steps of historic portages or watch bald eagle families soar overhead, you can walk across billion-year-old rock or pick apples as autumn leaves turn red and golden,” Bignell said in a press release. “It’s not surprising that the riverway and its parks are so popular.” The book is available via  hikeswithtykes.com.
