The construction and operation of the Alleghent Railroad was one of the greatest engineering feats of the 19th century. Hands-on exhibits and full-scale models in the Engine House Interpretive Building will intrigue visitors of all ages. Forested trails line the railroad and picnic areas, hiking trails, cross-country, skiing trails and ranger-led programs make this attraction one you will want to visit over and over. Be sure to stop by the restored Lemon House Tavern, too! Gallitzin Exit off U.S. Route 22, Cresson.
