Hi Lara,
If you start in Colfosco (near the tourist office), it’s a 11.8 km hike to Rifugio Gardenaccia.
Time Needed: 4:40 hours
Elevation Gain: 960 meters
Elevation Loss: 551 meters
I would consider starting the hike at Passo Gardena. From the pass, you can hike to Rifugio Puez via Forcella Crespeina. Take a look at the description in our Sass da Ciampac trail guide.
And then from Puez hut, continue across the plateau to Gardenaccia Hut.
Passo Gardena – Rifugio Puez – Gardenaccia Hütte
Distance: 12.9 km
Time Needed: 4:40 hours
Elevation Gain: 714 meters
Elevation Loss: 780 meters
Have fun!
