our calendar

Every year we do perhaps 2 or 3 major trips to one of the world's great ranges. Most typically, these include a visit to Peru or Bolivia, where we often enjoy a couple 2 or 3 week outings, and also a longer trips to Nepal, usually in the fall.

Though these destinations have become familiar to us, we also enjoy putting together custom trips, both to places we have been before as well as to destinations new to us. If you are interested in a climbing or skiing destination not listed below, give us a call. Odds are we can help you put it together or refer you to someone who can.

On this page we provide links to other pages in our site which describe more completely those areas and the trips we do there. See also our regular Alpine Climbing page where you can connect to climbs in the Alps, New Zealand, Canada and the Sierra Nevada.


Aconcagua is 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.

This expedition is offered by private arrangement.

Kyajo Ri, Nepal

Kyajo Ri is a seldom climbed 6186 meter peak in the Khumbu area. This is a technical route, with considerable belayed climbing primarily on snow and ice.

This expedition is offered by private arrangement.


We first went to Peru over 20 years ago, and have been coming back nearly every year, since. The peaks some of the most amazing looking things we have ever seen, with very sharp, ice-flocked summits. But also special is the entire experience of the trek in, the base camp with our good friend, cook, organizer and colleague Emilio Alvarado and the relaxed pace that an extended stay in the high mountains brings. Our time in Peru usually extends from mid-May to the end of June.


Every so often we make a variation of our Peru schedule and go to Bolivia. One of the best trips we have done there is to the northern end of the Cordillera Real, home to Illampu and Ancohuma.

Ama Dablam

In the fall months we often find ourselves in Nepal. Our schedule varies from year to year as we often do private trips. but one we do perhaps more frequently than others is Ama Dablam. In our opinion this is the most beautiful mountain in the world, and the climb of its normal route, the Southwest Ridge, is of very high quality. We are usually in Nepal from about mid-October to the end of November.

Mount Kenya

Though we have only been to Kenya a few times (Kathy three times and Mark once) we have enjoyed the trips so much that we recommend them here. Mount Kenya is a technical rock climb, and a very good one. In the summer and early fall and early season, the rock routes on the north side of the peak are in conditions (the North Face Standard Route on Batian, for example) while in the winter months, the south side routes, such as the McKinders route on Nelion, are in shape.


Years ago we made a trip to the Taghia Gorge, traversed the Atlas Mountains, then continued to the Todra Gorge for more rock climbing. It was a great outing and we felt it would make a superb trip for the rock climbing adventurer. The best time of year of this trip is in the fall, after the summer heat has abated a bit.

In addition to the destinations listed above, we can also arrange private trips in many other parts of the world. Please ask us about Alaska, Canada, Kyrgystan, or wherever you might be interested in visiting.
