Adventures no limits

On skis in the snow and with tanks under a frozen lake

Ice diving at 1,300 metres in the French Alps, in Courchevel. Twenty minutes of diving underwater without ropes to discover how far you can push your body and mind.

by Riccardo Barlaam

Cime innevate e immersioni sotto l’acqua ghiacciata: un modo nuovo di vivere la montagna. Courchevel, in Francia, è chiamata “la capitale mondiale dello sci”: conta su 550 chilometri di piste, un’enorme conca bianca che si stende lungo tre valli.

The rendezvous is at 10 a.m., at the edge of the forest, in Courchevel Le Praz, near the arrival of the ski slopes. There is a plateau that opens out in front of the alpine village, at this time all white. Snow and ice. In the background you can see the two ski jumps of the 1992 Albertville Winter Olympics. In summer it is a lake where people go for a walk or for a swim under the spruce forest. Some people also come here to fish. Freshwater fish, if there are any at this altitude.

We are at 1,300 metres in the French Alps, behind the Aiguilles. The names of the peaks here, which can be seen after Mont Blanc if you look towards France, are Aiguille de Chanrossa (3,045 metres), Aiguille de Péclet (3,561 metres), Aiguille du Fruit (3,051 metres). Rocks that pierce the sky, natural spires from which the Les 3 Vallées ski area opens up: Courchevel, Méribel, Val Thorens. "The 'skiing capital of the world', as they call it, has 550 kilometres of slopes: a huge white basin stretching along the three valleys, full of sun and snow for most of the season, thanks to the high altitude and the protection of the surrounding mountains, the spires.

Alcuni momenti dell’immersione di Riccardo Barlaam, giornalista de “Il Sole 24 Ore” e autore di questo pezzo, nel lago ghiacciato di Courchevel Le Praz. L’experience di icediving è stata organizzata da Ultima Hotel Courchevel con Courchevel Aventure.

The sun has not yet risen over the frozen lake, which remains in shadow. It is cold, the mobile phone reads three degrees. Le Praz, the alpine lake that stretches across the plateau, is 40 metres deep at its deepest point and now appears to me as a sheet of ice. On one bank, I find the Courchevel Aventure meeting point where I will prepare for what will be my first ice diving experience, an underwater dive in the frozen lake: it is a small 3-4 metre wooden hut near the path leading to the slopes. Inside, there is movement. A young man with a well-trained physique, a handlebar moustache and goatee, a shaved red hair-tail, a French beret lowered to a comma on his head and an infectious smile, tinkers with oxygen tanks, breathing apparatus and Gavs, the inflatable buoyancy regulating jackets. His name is Samuel Derycker, nicknamed by his friends Red wolf, the red wolf. Red because of his orange-red hair, wolf because, he says, he grew up in an alpine hut in the Auvergne, far from here. His school was the mountains. Now he is a diving instructor, but at altitude. Next to him is a French couple, Christophe and his wife, who are here for the skiing week. They come from La Rochelle, Aquitaine, on the Atlantic Ocean: he is passionate about freediving and wanted to experience the thrill - never is this expression more apt - of diving into a frozen lake. It is also the first experience of this kind for him. We proceed one at a time accompanied by the other instructor, Richard Dottin, who in summer works as a diving master on the Côte d'Azur near Saint-Raphaël, while in winter he continues to dive, but not in the tropical seas of the South, but here, in the cold, in the Alps.

I have always loved diving. The sensation of flying that you get when you start going down with your tanks in the first 8-10 metres of depth. Like a parachutist hovering not in the air, but in the sea, with the sunlight passing in rays through the water and becoming less intense the deeper you go. The blue becomes deep blue.

I think I have done about seventy dives over the years, I haven't counted them for a long time. But this is the first time in a frozen lake, at high altitude. At sea, if you have any problem at all, with the proper precautions - decompression, pauses during ascent - you can get out without much difficulty, you have an escape route. Not here. Above my head I have a layer of ice some twenty centimetres thick, like a very hard crystal, impossible to break.

We will have to go in and out of a square hole of about a metre near the quay where rowing boats dock in summer. I keep thinking about this as I put on my dry suit inside the small, unheated chalet. Another detail that makes me uneasy: I have always used traditional neoprene wetsuits, which are easier to manage in order to control buoyancy and empty the air that forms underwater between the skin and the fabric. I don't know what it will be like to dive with these wetsuits that don't let the water penetrate and wet the body, but which have a huge knob on the arm to empty the air.

Richard gives the briefing and explains how to proceed. We enter the hole one at a time, the dive will last about twenty minutes. The human body withstands extreme temperatures for thirty minutes and then goes into hypothermia. The cold, he says, could cause problems in the fingers. When diving, the thumb and forefinger are indispensable for closing the nose and compensating, pushing air into the ears to avoid trauma as the pressure increases as you descend. Richard warns us that our hands might freeze despite the plastic gloves: he advises, should they freeze, to use the two index fingers of both hands to close the nostrils, without the need to bend the fingers, thumb and forefinger, of only one hand.

Once in the water, we will make a circular path under the surface. At first we will be tied with a carabiner to a safety rope, but at a certain point Richard will release us and we will be free. But above all, we will have to be careful not to take the wrong direction to get out of the same spot from where we will lower ourselves.

The first to descend is our French friend. His wife and I wait for him, we follow the silhouettes of the two divers who can be glimpsed from time to time approaching the ice below us. Meanwhile, Samuel invites me to get ready: my turn is approaching. I begin dressing, then sit on one side of the hole, with my legs in the water: the temperature inside seems less rigid than outside, and my hands remain frozen.

Red Wolf hands me the tank jacket and helps me put it on. The cylinder valve, to prevent the first stage of the regulators from freezing, should only be opened at the last moment before the dive. Samuel tightens my fins, drops the mask over my face. And he opens it. I take one of the two regulators and start breathing with the tank.

Entering the water is a delicate moment. Informing myself before arriving here, I learnt that most deaths in cold-water diving are related to what they call cold shock: the body's reaction to extreme cold that activates the sympathetic nervous system and can have various effects, such as spikes in blood pressure, hyperventilation, and feelings of panic.

Apart from the cold and the fear of the uncharted world in front of me, I feel good. I try to concentrate on my breathing and slow my heart down. The technique to enter is to turn over your body and let yourself fall sliding, a bit like a walrus, to avoid damaging the cylinders on the ice. That's what I do.

I am finally inside, under the ice. I start to move around to find the optimal set-up. Richard with his hands asks me how it's going. My fingers are still warm, I signal that everything is OK. And as I begin to fin below the surface, attached to a line that keeps me tethered to the ice, the instructor helps me empty my wetsuit and let the air out to avoid the balloon effect and the risk of rising too quickly to the surface, which is what divers fear most. He continues to tinker, I watch him and breathe, trying not to pant. I feel the cold, especially in my hands, feet and face, in that part of the skin that remains outside the mask. All in all, it is bearable: I keep thinking that it was colder outside.

We arrive at the fateful moment: Richard detaches the carabiner and we start swimming in the blue without the safety rope. Side by side, we move slowly. With the same rhythm I try to breathe. It is as if everything is now in slow motion. As we get closer to the bottom, the water turns dark green, like the stones and the layer of mucilage covering them. Above, if I turn my head, everything is iridescent white: the ice looks like a contemporary work of art that changes its appearance under the light and with our movements, it enchants me. We swim towards the centre of the lake. I feel no breathlessness, I continue to breathe slowly, suspended between water and ice. We continue in a circular circle following the lake and back towards the quay. We finally pass between the boulders and under the concrete pylons supporting the jetty as we approach the hole. We get out, Red Wolf helps me by pulling me from under his arms.

The sun has now risen. The lake is illuminated and I don't feel cold, I think because of the adrenalin. I enjoy the feeling of this magical moment and the sense of vitality after this extreme experience. My French adventure partner hugs me and smiles, I return the warmth. We immediately go to change in the little house and warm up: few times have I felt as alive as I do now. The day in Courchevel and its six villages continues. The sun and the ski slopes await me.

I am in Courchevel Moriond, in the sunniest and least busy part of this Alpine resort, to the east of the resort. A guest at the Ultima Hotel Courchevel, thirteen chalets with a view as far as the eye can see of the mountains and La Rosière forest. It is a hotel of private villas, from which you step out directly onto the slopes, with a service that is punctual and omnipresent, but very discreet: each chalet has five rooms, four bathrooms, and a lift from one floor to the next. There could be twelve of us, but instead I am here alone, enjoying a butler all to myself and a chef who cooks in the chalet. Plus, the two spas with indoor and outdoor pools, a cinema room and a sportswear boutique. Leaning on Courchevel Aventure, the resort allows its guests to participate in experiences like the one I had today.

Courchevel is a destination for snow enthusiasts, a concentration of starred hotels and restaurants, and has a small airport next to the ski resorts, with a short run (525 metres) that ends up in the void like in a 007 film, only practicable with small planes such as Cessnas or for helicopters. There are also four long groomed trails through the woods for ascending on ski mountaineering skis and then descending to the valley, as well as cross-country skiing trails, snowshoeing and dog-walking trails, a 2.5-kilometre toboggan run, and icefalls: an area so wide that, however busy it is, there is never a crowd at the start of the lifts or on the slopes. Here you can preserve that contact with nature, silence and solitude that the mountains can offer.

I stay until sunset with my skis on. I skied all afternoon with the ski lifts, but I reserved the last hour for ascending on mountaineering skis and skins from the slope that leads from Courchevel's Ultima Hotel up to the Belvédère plateau, where a cross-country skiing loop starts, and then I climbed further, step by step, up the Crêtes de Pralin, the ridges that skirt the valley and the coniferous forest and reach Mont Bel-Air, at an altitude of 2.050 metres, from where a spectacular view opens up towards the Vanoise National Park, with Mont Blanc in the background. The view is unique, the air is pure. I wait for the last light before returning to the chalet. The spa awaits me, in contemplative solitude. Surprisingly, as I sip a herbal tea after a regenerating sauna, I discover that they have reserved a long back massage for me, with which I end this day far from stress, but full of discoveries, truly unforgettable.
