For the railfan or history buff, the Cresson area is a Pennsylvania treasure trove. Immerse yourself in railroading history at the Horseshoe Curve, a marvel of 1854 engineering that continues to be a vital passage. Then delve deeper at the Gallitzin Tunnels Park & Museum, where you’ll witness modern trains conquer the mountains through the very tunnels that challenged engineers in the 1850s.  There’s also plenty to see and do in nearby Altoona or Johnstown.
