StoriesJuly 2024

The west face is striking, the normal route is lined with colourful flowers and the views from the summit are breathtaking: the hike up the Tour d'Aï has a lot to offer and takes us from Leysin to this 2,331 m high mountain high above Lake Geneva.

And one last time we have to balance on tiptoe over a passage several metres long made of cow dung, then it's done and we can tackle the rest of the descent from the Tour d'Aï with dry feet. We already had to walk along here on the ascent, but by now the cow poo has at least dried out, which makes things a little more pleasant.

About three hours ago, we started our hike up the Tour d'Aï in Leysin, this unique mountain village high above the Rhone Valley at an altitude of 1,252 metres. The three of us first walked through steep little streets with international schools and colleges, heard a wide variety of languages of all colours on the streets and then turned off to climb up towards the Tour d'Aï. A good 1000 metres in altitude were ahead of us from Leysin, the last 400 of which were exposed on the south-facing normal route, a white-blue-white marked mountain path up to the striking summit of the 2,331 m high Tour d'Aï.

Stone cathedral

Tour d'Aï, a strange name and a bit of a trick to find this ‘ï’ with its colon on the keyboard. But even in nature, this mountain is not like any other. Its vertical to overhanging west face, traversed by a via ferrata, breaks off impressively into the basin in which the Lac d'Aï stores water for the winter snowmaking of the Leysin ski area. The view from the summit is also impressive, accessible via a long ridge from the south, which today in July resembles a sea of alpine flowers. But we're not there yet, we first have to hike up a few metres in altitude along an asphalted alpine road until we reach the cosy Alp Le Temeley at 1,705 metres. If you like typical Valais dishes, you'll find them here - but it's still too early in the day for us and we quickly leave the alp, the alp road and the tedious alp road behind us as we start to climb northwards through a colourful sea of mountain flowers directly up a steep mountain path towards Lac d'Aï.

It's incredible what grows and thrives at this altitude. As a complete layman with a degree in alpine flora, I don't have much choice but to classify the flowers according to their colours - but still: even without in-depth knowledge, which I have to leave to Marina as a qualified environmental engineer, the sight is beautiful and masks the fact that we are walking around on the ski area's pistes.

At 1,910 metres, we reach the Tête d'Aï and after a refreshment break, our route continues straight up a steep, rocky gully bordered by the long, grassy ridge of the Tour d'Aï. The path zigzags upwards, soon followed by the key section of the normal route on the Tour d'Aï, a short passage with two rocky ledges with metal cleats and steps. One is a little longer, the other only a few metres high. Our hands have to come out of our pockets, but our hearts don't have to slip into our trousers, because after just a few seconds this section is behind us and another colourful sea of flowers lies ahead.

Colour spectrum

Yellow, blue, purple and pink, with a green mat underneath: this is how the following path up to the rocky summit of the Tour d'Aï presents itself. Thousands of flowers are lined up one after the other, and there are not quite as many hairpin bends, which quickly bring us to another short, rocky passage. Here, too, we have to make a brief effort before the path winds its way stealthily to the east side. We then climb the last few metres from the northern side up to the panoramic Eldorado of the Tour d'Aï.

Above the sea of clouds

If this view from the summit of the Tour d'Aï isn't enough for you, you're probably beyond help. Lake Geneva, the foothills of the Alps and, in the other direction, mountains, mountains and more mountains. Low mountains and high mountains, even the highest mountain in the Alps, Mont Blanc, is not to be outdone and sends greetings from its white summit cap of eternal ice. Its only slightly lower neighbour, the Grand Combin, is also unmistakably visible at the end of the Val de Bagnes. And in between, the granite peaks of the countless mountain giants around Chamonix, in the triangle of Switzerland, Italy and France. The silvery dome of the Berneuse glistens directly in front of us, also accessible by cable car and recommended photo point in the evening sun.

Eat, drink, look, even in a different order - we don't have to do much more here at the summit. But we shouldn't put down roots, because we still want to go down. And so the ascent is followed by the descent, again passing countless alpine flowers and quickly losing metres in altitude. A lift awaits at the Tête d'Aï, but we ignore it and instead descend in a left turn via Alp Mayen. And not so much later, we find ourselves back at the cowpat passage - but this time we get over it a little drier and a little later arrive on the tarmac road back to Leysin, on which we are soon seen trotting back to Leysin without having to pass any more alpine by-products.

Back to the valley

We looked for and found a striking summit - but above all, we were able to discover unique alpine flora that more than deserves the term ‘colourful’. It appeared unexpectedly, but it is usually these unexpected things that we remember and that turn a simple mountain tour into a lasting experience.

Route description

We start our hike on the Tour d'Aï in Leysin at a car park just below P. 1356. We briefly follow Avenue Secrétan in a north-easterly direction until a small hiking trail branches off to the left. We follow this for just under 200 metres and then turn sharp right again. Shortly afterwards, we reach the Route des Chamois and keep left until we reach P. 1474, which then leads us along a marked path towards Le Temeley.

Cross alpine pastures (some of which are grazed by suckler cows) on the tarmac alpine road, which is closed to public transport, up to Alp Le Temeley. Directly behind the double hairpin bend, a hiking trail would lead up towards Berneuse. However, we stay on the alpine road for a little longer and only leave it to the left at P. 1729. If there are suckler cows grazing in this area and you want to avoid them, you can follow the yellow-marked path straight ahead and then take a long left turn to reach the Tête d'Aï.

Follow the partly steep hiking trail up to just before Lac d'Aï and keep right past the small Alpweiler at 1,892 metres. Directly behind the mountain station of the Tête d'Aï, the white-blue-white marked mountain path turns off to the left in the direction of Tour d'Aï. Following this, you soon reach a rocky gully, the upper section of which you climb over a few short steep steps with metal stirrups, ladders and wire ropes. In terms of difficulty, this passage is the key section of the normal route up the Tour d'Aï; it doesn't get any more difficult after this, although it is more exposed.

Climb up over the soon broad south-east-facing ridge to another small rock step with another short secured passage. The route then runs along the east side of the Tour d'Aï, partly exposed, and passes several small towers on the ridge. These passages are technically easy, but exposed in places. A head for heights is a basic requirement here. After a sharp left-hand bend, you soon reach the summit with breathtaking views in all directions.

The upper part of the descent follows the ascent route. From the Tête d'Aï, there are various options for descending back to Leysin in the valley, all of which are well marked, but in places lead across alpine pastures with suckler cows. Alternatively, you can take the cablecar down into the valley from here.

Difficulty

T3+ (SAC scale). The route described is not the via ferrata, which is rated K4. The mountain trail is exposed in some passages in the upper section. A head for heights and sure-footedness are absolute prerequisites for walking the route.

Key passage

Short passages with ladders and chains in the lower part of the summit structure

Best season

For the hike to the Tour d'Aï, all the remaining snow should have melted away in the upper, exposed section after the Tête d'Aï, which is normally the case in early summer from May or June. After that, the hike is possible into the autumn until the first major snowfall.

Arrival

Leave the A9 motorway in the direction of Montreux or Sion in the opposite direction at the Aigle exit and follow the marked road to Leysin. Shortly before La Sépey, leave the cantonal road 11 and follow the smaller road up to Leysin. Follow the narrow road through Leysin to the car park on Avenue Rollier.

Starting point

The starting point is the car park below P. 1356 in Leysin, but all other car parks in the village are also possible. Due to the geographical location of Leysin, parking is limited and the access roads are narrow in places.

Good to know

Varied and in the upper part more demanding alpine hike to the striking summit of the Tour d'Aï.

Some passages are exposed and require a head for heights.

A steep via ferrata leads up the striking west face of the Tour d'Aï to just below the summit. Complete via ferrata equipment with harness, via ferrata set and helmet is required.

The starting point is the small mountain town of Leysin, which nestles high above the Rhone Valley on the slope. Leysin is home to the Leysin American School and a renowned hotel management school, giving the village an international flair.

With an ascent of around 150 meters, you can climb up to the revolving restaurant Le Kuklos on the Berneuse (cable car to the valley to Leysin) and enjoy the impressive view of the Rhone Valley.

Refreshments are available at the Refuge de Mayen, in the Cable Car bar at the foot of the cable car in Leysin, in the cozy Buvette d'Aï at the foot of the Tour d'Aï or in the valley in the Restaurant Le Bel Air.
