We are an international climbing and skiing guide service owned and operated by UIAGM / IFMGA Certified Mountain Guides Kathy Cosley & Mark Houston. We specialize in small-group and custom climbing and skiing trips and expeditions to the great alpine destinations of the world. Our programs include mountaineering, rock and ice climbing, expeditions and ski mountaineering.

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.

This mid-winter tour is for those that like powder. We spend 6 big days touring, staying in either hotels, gîtes or huts, all equipped with showers!

This is a great introduction to hut-to-hut touring in the Alps. The Silvretta Group offers great huts, big terrain, and a very wide range of objectives from which to choose.

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.

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.

This is a great high altitude expedition for experienced climbers. Chopicalqui is a beautiful summit in the very center of Peru's Cordillera Blanca. To acclimate, and also for the fun of it, we'll climb several other summits in the Ishinca area, including 6032 meter Tocllaraju.

In a new kind direction, Kathy will offer a cultural tour in the Hautes Alpes region near Briançon in June. This tour focuses on pastoralism and combines light hiking in the Queyras mountains, with workshops in such fiber arts as felting, vegetable dyeing, and hand spinning, led by some new friends she has made near Serre Chevalier..

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 climbers 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 (below), but offers the rewards of a greater challenge.

The classic Swiss countryside trek. This is a 6-day trek with an optional 3-day add-on ascent of the Wildstrubel. The trekking portion links remote villages in what is arguably the most quintessentially "Swiss" alpine scenery in the country. We stay in small hotels and inns, and the trekking is on trails (though occasionally quite rough). The optional Wildstrubel ascent is a great introduction to glacier climbing and offers a fine finish.

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

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.

In January of 2013, we are heading back to Argentina to climb the highest peak in the western and southern hemispheres. Our route of choice includes a traverse of the peak, ascending the Vacas and Relinchos valleys to the Plaza Argentina Base Camp, and descending via the normal route on the Horcones side.
