The Grutas de Garcia Aerial Tram takes visitors to the Garcia Caves inside the famous mountain, El Fraile within the Cumbres de Monterrey National Park. The tram travels a distance of 625 meters in 5 minutes reaching an elevation of 280 meters to where the caves are located. The caves were accidently discovered in 1843 by priest, Jaun Antonio Sobrevilla while he was exploring the area. Consisting primarily of limestone, the caves feature many stalactites and stalagmites. Rocky Mountain Lift Services & Supplies was contracted out to perform inspection and maintenance services on the aerial tram.
