Join the Friends of Fort Harrison State Park as we celebrate the 25th anniversary of Fort Harrison State Park in the form of our 2021 Trail Challenge! This is a non-competitive activity to explore all of the park's trails by the end of the year at a pace that suits you! If you’d like to commemorate the challenge, feel free to buy the trail challenge t-shirt while supplies last ($20/shirt). All proceeds go to the Friends of Fort Harrison. *Please note that these shirts are available CASH ONLY at the Visitor Center. Card payments will be accepted at naturalist-led hikes by a Friends of Fort Harrison member.
