Day 1
Meeting with the mountain guide at 2 PM at the Frachey cable cars, where we will check the equipment and distribute the technical gear. We will drive by jeep to the upper Verra plains, where the trail to the Lambronecca refuge begins, perched on the edge of the large Verra glacier, offering spectacular views of the Breithorn range. Dinner and overnight stay.
Day 2
At dawn, we will ascend the Grande Ghiacciaio di Verra to the base of the southern ridge of Polluce. Depending on the conditions, we will tackle a steep snow slope or a mixed ridge that will lead us to a chimney equipped with chains. After passing the chimney, we will reach the summit ridge, where the statue of the Madonna with Child is located. After adjusting our gear, we will face the spectacular snowy ridge that will take us to the summit of Polluce at 4089 meters (about 2.5 to 3 hours from the refuge).
After descending along the same route, we will continue towards the majestic west face of Castore. The ascent, zigzagging between crevasses, culminates with a final 45° pitch that will lead us to the final ridge, offering breathtaking views of the Swiss side of Monte Rosa. We will reach the summit of Castore at 4225 meters in about 2.5 hours from the Ghiacciaio di Verra.
The descent towards Colle Felik will challenge us on a horizontal ridge, providing an opportunity to better understand what the traverse of the Lyskamm entails, always visible ahead of us, and perhaps consider it as a future project.
From Colle Felik, we will descend a 40° slope that will take us to the calm Ghiacciaio del Felik and the Quintino Sella refuge. To return to Frachey, we will follow the equipped ridge of Ometto and then the trail towards Colle della Bettaforca, from where we will descend by off-road vehicle.

Practicing mountaineering involves risks, including severe or fatal injuries. All Monte Rosa guides are certified by IFMGA and are committed to minimizing dangers. It is important to know that risk cannot be completely eliminated, and this is an aspect you confirm you accept by signing a reservation contract for an ascent with us.
The guides will assist you in reaching your goals and in having an enjoyable experience. It is essential to trust their judgment and accept the decisions they make. Being well-prepared and in good physical shape is crucial to ensure safety during the ascents.
If the guide believes you are not ready for the booked ascent, they will suggest an appropriate alternative. In the event of unexpected bad weather that makes the ascent dangerous, the guide will propose a mutually agreed alternative ascent.
