Particularly exciting and panoramic is trail 645 that begins in Colfosco and passes by the viewpoint Crëp de Sela. This 5 km long hiking trail at the foot of the impressive walls of the Sella Group is absolutely perfect for a deep immersion into the splendid Alpine scenery. Priceless are the views over the graceful volutes of Sassongher and over the village of Corvara with the background of the highest peaks of the Dolomites. As soon as you arrive at the crossroads with trail 639, follow it downhill until Ütia Crëp de Munt.
