Upcoming Trips

We are not booking any "open" trips this year. (largely due to everyone's favorite pandemic).
But we are happy to take private bookings.
The ski trips listed here are suggestions.

off-piste skiing

With a base of your hotel in Chamonix, you can enjoy an amazing variety of off-piste skiing at nearly any level of difficulty. Many route are possible on downhill "alpine" ski gear, while others need randonnée skis with skins.

best season: Mid-January to Mid-March

Queyras ski
touring, France

This quiet corner of the Alps is known for powder snow and sunshine. Think "Colorado" with huts that have showers and a full bar. In our Queyras tour we spend 6 days skiing, staying in both hotels, gites as well as three nights in mountain refuges.

best season: February

Ski Tour

The Silvretta group straddles the border between Italy and Austria. Our 6-day tour starts on the Austrian side and visits 3 huts, the Heidelberger, the Jamtal and the Wiesbadener. This is a prefect choice as an introduction to ski touring in the Alps, with comfortable huts (showers!) and superb touring terrain.

best season:
February and March
Tour du Soleil

The Tour du Soleil straddles the Swiss/Italianborder. We traverse from the Binntal hut, near the Nufenenpass, to Realp, not far from Andermatt. Sunshine, great huts, and lots of options.

best season:
late February to late March

This tour is one of our favorites. Great huts, fantastic ski descents, and big, glaciated peaks. We have 7 days of skiing starting and ending in Sulden, Italy. The daily routine: get up, enjoy a fine breakfast, climb another big peak, have a great ski down, shower, relax in the bar, dinner, to bed, and repeat. The perfect tour for skilled and adventurous skiers who enjoy their fun.

best season:
early March to late April

Haute Route

This is the classic Chamonix to Zermatt ski journey. Our 8-day program starts with a day of off-piste in Chamonix (usually the Vallée Blanche) and cruises into Zermatt a week later. We'll stay at the Trient, Mont Fort, Prafleuri, Dix and Vignettes huts as we wind our way through the highest and most impressive section of the Alps.

best season:
late February to late March

Berner Ski

The Berner Oberland is a vast complex of giant valley glaciers and big peaks. This country looks more like Alaska, with immense glaciers, big icefalls and long descents. Unlike Alaska, however, there are comfortable huts and easy access from the Jungfraujoch train. 6 days of skiing, staying in a new hut every night (except the two we spend in the very nice Finsteraarhorn hut.

best season: April to early May

Haute Route

This version of the Chamonix to Zermatt Haute Route avoids the more rigorous glaciers and off-trail hiking of the "Glacier Trek" (above). But even though the route stays on trails, and lodging is in more comfortable village inns, it is still a demanding hike, with some big days. The entire program is 9 days of alpine trekking.

best season: July to September
Glacier Trek
Haute Route

This is a challenging high altitude trek linking the Chamonix Valley and Zermatt. For much of this route we are on glaciers or off-trail, on climber's paths and routes. We'll stay in mountain huts, rise early and enjoy long days in high alpine terrain. This 7-day route is distinctly more difficult than the Walker's route, but offers the rewards of a greater challenge.

best season: July

Alps Summer

We spend every summer guiding in our backyard, the Alps. Let us know if you think you might like to join us.
