This path goes from San Candido (1173 m) in Val Pusteria (BZ) to Pieve di Cadore (880 m, BL), being approximately 90 km long. Technically challenging despite its relatively short length, this Alpine Path is renowned for its peculiar and fascinating high mountain sights. Named after Paul Grohmann, the famous Austrian explorer who did many ascensions in the very zone which now is crossed by the path. This path has many equipped sections that can be very exposed and/or challenging, and unlike other Alpine routes, there are no easier ways around those, so a certain degree of experience is required. In the final section path n.4 merges with path n.5, precisely from Rifugio Galassi until the end in Pieve di Cadore.
