Castore SE Ridge Normal Route

Castore 4226 m - Castor in German – is a magnificent snow-capped peak belonging to the Monte Rosa Group, Pennine Alps, located on the main alpine watershed on the border between Aosta Valley (Italy) and Wallis (Switzerland), between Colle di Verra and Colle Felik. Castore is a massive peak, but at the same time it shows elegant shapes. Castore with its 4226 meters above sea level is one of the favourite destinations from the Refuge Quintino Sella. It's higher than the adjacent Polluce (Pollux), together which it forms the  small group of Gemelli.

If climbed along the South-East Ridge Normal route,  Castore is one of the easiest Fourthousander of the Alpine chain.  Check here the complete list of the 82 alpine Fourthousanders and the 46 minor summits: Club4000.   Moreover this route is truly spectacular, following airy snow ridges - so don’t expect to be alone, rather be sure to meet a lot of people… - and the view from the summit is great.

From the parking area a cable car leads 300 meters further up, where a chair lift by a long run leads up to Passo di Bettaforca m 2720. Here take the obvious path n. 9 to the Quintino Sella shelter, rising on the crest and getting quickly to the Bettolina Pass m. 2905. From here carry on the wide crest to the junction with the path coming from Pian di Verra. Follow the yellow marks, climb up some easy rocks, then follow the final airy ridge, equipped with fixed ropes, leading to the terrace on which is located the Rifugio Quintino Sella m. 3585.

From the shelter reach the Felik Glacier and follow its gently angled slopes North direction, heading to Punta Perazzi. Here head towards NE - crevasses - leaving Colle Perazzi on the left and reaching the bottom of the steep ice-slopes below Colle Felik. The best solution is to pass the bergschrund on the right. After the bergschrund climb the steep slope, gaining Colle di Felik 4061 m. (about 2 hours from the shelter).
