Castor Mountain, Pennine Alps, 2 Day Guided Ascent

One of the IFMGA-certified guides in the Peakshunter team wants to lead you on a 2 day climb of the stunning Castor mountain in the Pennine Alps, next to its twin peak, Pollux.


Private and Group




2 Days


Jun - Oct






Credit Card, Wire Transfer and more!


The bigger of two beautiful peaks, Castor (4,226m) stands to the right of its ancient twin, Pollux (4,091m).

Located in the Pennine Alps, on the border between Switzerland and Italy, Castor is a gorgeous peak. From its snow capped summit, you will have an unforgettable view of some of the Pennine Alps' most famous peaks. From Breithorn (4,164m) to Monte Rosa (4,634m), you will stand in awe of the majestic mountains standing before you.

Like its aptly named twin, Castor is not a difficult climb. This will enable beginners to gain valuable climbing experience as you make your way to the peak. Also, for those experienced climbers that want to reach the top of this mountain, it will only further enhance your abilities. However, regardless of your skill level, Castor is a peak that will provide whoever wants to climb it with breathtaking views of the surrounding Alps.

Firstly, we leave from Gressoney to the Bettaforca pass. Once there, we will walk for 2 to 3 hours until we reach the Refuge Quintino Sella (3,585m). On day 2 we will spend between 6 to 7 hours ascending and descending Castor.

When it comes to which mountains to climb in the Pennine Alps, Castor definitely comes to mind. It is a beautiful peak. One that offers fantastic views of the Alps, while also offering a perfect view of its twin, Pollux. If you want me to guide you to the top of this wonderful mountain, just send me a message.

And if you want to climb Pollux, I can also guide you on this 2 day climb.

Meeting point


How far in advance should I start training and what kind of training do you suggest?

In the months leading up to the trip, we recommend consistent training to improve your endurance and your cardiovascular fitness (running, hiking, biking). When you confirm the trip, we will send you specific recommendations about the training.

Will I need to bring any technical equipment of my own? Is it possible to rent equipment, and if so, what would be the approximate cost of that?

The loan of the personal technical equipment is included in the tariff; the guide provides it on the day of departure. The gear for rental includes a mountaineering harness, straight-hand ice axe, and crampons.

In addition, the guide will bring the common safety gear, such as rope, ice screws, daisy chains, and carabiners.

All you need to check and bring is your personal mountaineering clothing, including technical mountaineering boots, waterproof, and rigid soles (please avoid bringing new ones you have never used before the ascent!).

After your booking confirmation, we will send a complete and detailed list of recommended equipment and clothing. If you need anything for rent, we will recommend some shops where you can hire the necessary gear.

Boots renting is around 20-22€/day, and trekking poles are 15€ per person.

Will there be porters to help to carry group and personal equipment?

Absolutely no porters are expected for this ascent. Each participant should bring a personal backpack and technical equipment, including a thermos for tea/water and energy bars/dried fruit and energy food for the trip.

How will accommodation and meals be handled on the mountain?

We will take care of the accommodation booking that includes the overnight stay at the Quintino Sella hut with half-board formula, which includes breakfast and dinner, but not the beverages/drinks or the extra meals for the clients and for the guide.

Any other extra meals and all the beverages for clients and the guide are NOT included and have to be covered by the customers directly on the spot.

What happens in the event of bad weather?

A few days before the trip, the guide will inform all participants about the weather forecasts and general conditions expected for the itinerary (temperatures, wind, snow conditions, etc.).

In case of bad weather, we will do our best to offer you an alternative program or move the date a few days later, depending on customer availability.

Are there any other special requirements such as permits/insurance/vaccines that we need to consider before the tour?

Yes, there are several special requirements that you need to consider for this trip. Here are some of them; please read them carefully before confirming the booking.

  • It is strongly recommended to have rescue and research insurance; if you need one, after your confirmation, we can recommend some solutions suitable for you.
  • There are no specific vaccine requirements for this trip, but it is always a good idea to check with your doctor or a travel clinic to make sure you are up to date on routine vaccinations. Also, there is no longer a need to provide proof of vaccination, recovery from COVID-19, or negative test results.
  • We finally invite all non-EU citizens to inform themselves about specific permits to enter Italy.

What is the guide-to-client ratio to climb this mountain?

For Castor the guide-to-client ratio is 1:3. This is the maximum number in order to ensure your and the guide's safety. If you are a group of more than 3 people, we have more guides available to undertake the adventure.

What is the best time of the year to climb this mountain?

The best time to do this ascent is from the beginning of June to middle of September.

Can I join a group?

Yes, you can choose to book a private tour or decide to join a group to reduce the costs.

We have already confirmed and planned group trips, departing in 2024; check the best date for you in our calendar.

Before confirming a group tour, please remember that you will share the ascent with other climbers who could have a different fit and previous experience. The guide will be responsible for the entire team and in any case or reason, it could guarantee the summit if only 1 participant has physical problems or isn’t enough fit to respect the timetable for the ascent and descent. The decision to share a trip with others to reduce the total costs requires accepting to be part of a team, in which adaptation and capacity for mutual support are essential requirements for all participants.

If you evaluate your fitness level and your technical skills as too low or inadequate to the abilities and efforts that this demanding ascent requires, you probably should take the PRIVATE trip, as the best option for you.

How can I reach the meeting point?

The meeting point is in Gressoney Staffal, at the bar Wunderbar, next to the lifts ticket desk, reachable by car from the Pont-Saint-Martin exit (Milan-Turin highway) in about 50 minutes, or by public bus service (Arriva company).

At what time will we be back to the parking area?

The meeting with the guide on the first day will be around 12:30 am (please remember to check the bus timetable in case you need to reach the meeting point by public transport).

The time back to the parking area on the second day is expected around 3:00 pm.

Is this trip suitable for children? Which is the minimum age for participants?

Yes, the ascent could be done even by young people (the minimum age is 14 years, depending on the fitness level and skills). They must be accompanied by at least 1 parent. We ask both parents to fill out and sign a release form for their children, with privacy consent and self-declaration of responsibility.

What additional costs should I consider?

The hiring of the trek poles and the renting of the boots are NOT included.

If needed, the renting of the boots has to be done by the customers before the trip in one of the shops in Gressoney. We will send you more details in case of need.

The costs for beverages and extra meals for the clients and the Guide are NOT included and have to be covered on the spots, sharing the guide’s fee between all the participants.

The transfer to the meeting point is NOT included.

What people are saying about -PeaksHunter



Gabriele was a fantastic guide, knew the area well and found so much powder. Thanks so much



Hello Basically I am satisfied with the whole organization, because in the end everything worked as expected, whereby the guide had a big part in the success! Unfortunately, the information regarding equipment was unclear in advance and sometimes varied, which didn't make it any easier for a beginner like me. In general, the flow of information was rather slow, but towards the end it was sufficient and quick. In general, I would recommend that you revise the list of necessary equipment! Above all, it should be clear what the guest has to bring (with a distinction between "must" and "recommended"), what is provided by the organizer and what could be rented if necessary. Of course, this is not easy to accomplish, as the necessary equipment also depends on the conditions. Best wishes and continued success with the organization of ski trips! Martin



Great service. Above and beyond expectations. Abigail went the extra mile to make my trip happen, after hours and at very short notice. It would not have been possible without her. Highly recommended.



Hi, good service from explore share and peaks hunter, only some miscommunication on 2 or 3 days program, due to bad communication between you both. The guide was OK, friendly although non very experienced in the practice of pédagogie and communication, especially before couloir des Goûter s, there can be better briefing on security and also in general on the whole expedition. But he can grow by learning some coaching lessons. We did not do the final ascension due to bad weather, a proposal and financial compensation for 2nd attempt would have been welcome.6/10.can do better.


We just remember now the breathing, the view and the joy we had in Gran Paradiso accompanied by our guides Silvia and Elis. This kind of memory makes us smile and look for the next adventure. Silvia and Elis were attentive, kind and professionally fully prepared to help us reach a great experience of discovery and safety. For sure the moment would not be the same without our guides. We feel grateful and lucky to have their support and company. Elis, Silvia, thanks for taking us beyond.
