My goal

The Pollux Castor Traverse traverse is a captivating loop that connects two of the most beautiful 4000-meter peaks of Monte Rosa. It is an extraordinary, challenging, and varied experience. Choosing the traverse means engaging with all types of high mountain terrain, immersed in one of the most stunning landscapes of Monte Rosa. It serves as a central stop on the Spaghetti Tour, and offers a high mountain experience that introduces you to the world of high-level mountaineering. The base camp is the beautiful Ayas Guides’ refuge, nestled below the Breithorn, which can be reached from Champoluc in just over 3 hours.

The price includes: IFMGA mountain guide for the 2 days of the tour, off-road taxi from Saint Jacques to the upper Verra plains, half board at the Lambronecca refuge, technical equipment, off-road taxi from Colle Bettaforca to Frachey.
Not included in the price: accident insurance (recommended), meals not specified for yourself and the guide, everything not listed under “the price includes”.

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.

We use this one.

Mountaineering, ski touring, off-piste skiing and trekking take place in a natural, uncontrolled environment.
Weather conditions, snow, ice, terrain, visibility, altitude and physical fatigue can change rapidly and directly affect the course of the activity. For this reason, there is always an inherent level of objective risk, which cannot be eliminated but only managed.

All our activities are led by IFMGA Mountain Guides and Certified Hiking Guides (AMM).
The guide continuously assesses environmental conditions and the physical and mental state of participants, sets an appropriate pace, manages progression and ensures the correct use of equipment. If conditions require it, the guide may modify the itinerary or interrupt the activity, always in the interest of individual and group safety.

Participants are required to be in good physical and mental condition, adequately prepared for the level of the activity, and to follow the guide’s instructions at all times.

Group activities

During group outings, the pace is set according to the slowest participant. In case of fatigue or discomfort, the guide may decide to adjust the programme or return early. In the mountains, the group ascends and returns together.

FAQ #1 – Will I suffer from altitude sickness?
High altitude can cause altitude sickness, with symptoms such as headaches, nausea, fatigue, and difficulty concentrating. Gradual acclimatization helps reduce the risk and intensity of symptoms. Being in good physical shape and well-trained makes the experience less exhausting.
FAQ #2 – Are there any medications that can help with altitude sickness?
Altitude sickness is highly subjective, and there is no one-size-fits-all solution. It is advisable to bring only the headache and nausea medications that you are already familiar with and have used before. Nevertheless, we recommend consulting your primary healthcare provider for personalized advice
FAQ #3 – What happens if I feel unwell during the ascent?
If you feel unwell in the hut, we will organize an early descent. In the case of severe discomfort during the hike, we will turn back. In the event of severe illness, the guide will alert the rescue services, and you will be taken to the hospital by helicopter.
FAQ #4 – Can I join a group if I’m alone?
Certainly! Choose your experience from the group hikes page by clicking here
FAQ #5 – Do I need a sleeping bag?
No, Monterosa’s refuges provide pillows, duvets, or blankets! However, the use of a sleeping bag liner is mandatory, and you can purchase it for a minimal cost at specialized stores. Click here for more information (affiliate link)
FAQ #6 – Can I rent high mountain clothing and equipment?
You can rent equipment (boots, poles, ice axe) in Alagna, Gressoney and Champoluc. However, it will not be possible to rent clothing.
FAQ #7 – If I do not reach the summit, will I be refunded?
No, no refund is provided.
FAQ #8 – What is the required fitness level for the excursion?
To successfully complete this experience, you need good physical endurance and training that allows you to sustain at least 4/5 hours of uphill walking plus the same amount in descent. Preparing with specific training will help you tackle the challenges of the route and fully enjoy the adventure.
