The Autism Nature Trail (The ANT) at Letchworth State Park is a first-of-its-kind experience in nature designed for visitors on the autism spectrum and with a range of abilities—appropriate and enjoyable for all abilities and ages. The ANT is a one-mile looped main Trail with eight stations at various intervals, offering a range of experiences from quiet engagement to active exploration and adventure. The ANT is located adjacent to the Humphrey Nature Center, inside Letchworth State Park. To visit, use the Castile entrance to Letchworth during park hours. Once inside the Castile entrance, it takes about 5 minutes to reach The ANT by car, following the signs.
