Walk with dinosaurs, sail through a Great Lakes storm, paddle in a kayak, or snowshoe the backcountry. Whatever the season, there are always things to see and do in the Sanctuary of the Great Lakes.
Biking is one of the best ways to explore Alpena! Plan your adventure with the Friends of the Thunder Bay National Marine Sanctuary! We offer a great selection of Raleigh bikes for men, women and children as well as Burley child trailers and tag-alongs. Explore the Maritime Heritage Trail, the 16.5 mile long Alpena Bi-Path or grab a map and head out on a number of self-guided tours. Bikes are available seven days a week on a first-come, first-served basis. All rentals require a security deposit. For your safety, please wear a helmet – provided with your rental – and obey the rules of the road. For information on availability and selection, contact the Sanctuary Store at (989) 356-8805, ext. 18.
