Andes Website : Climbing, Skiing, Trekking and Guidebooks in South America

Site Contents     

 Site last updated on Friday 05th July 2024.

Take a look at our calendar of expeditions for the rest of 2024 and first half of 2025. It features new trips like our First Ascents in Bolivia and our Peru Ski Explorer, alongside older itineraries such as our Patagonia Ski Explorer and a return visit to Aconcagua in February 2025.

Throughout the 2010's we made a number of first ascents of 6000m peaks in the high Andes of the Argentine Puna de Atacama and climbed new routes in remote Peruvian ranges (see our Firsts page for further details). These were very successful expeditions with many clients making many summits. We are heading back to the Andes in December 2024 for a similar trip, but this time to a remote corner of Bolivia. The peaks we will head to are in an area of the Andes we know  well, having run several successful trips in the past few years. Read more here....


Information about the climbing and trekking guidebooks to the Andes which John Biggar has authored. These have been translated into French, Spanish, Czech & Polish. You can purchase the English edition through this website. The 5th English edition was published in February 2020.


We can provide or organise logistical support for many types of mountain expeditions, in many parts of the Andes. In the past ANDES have organised treks, ski holidays, expeditions and guided climbing for private individuals, groups of friends, schools, clubs and military groups

Scheduled Courses & Expeditions

Every year ANDES schedule a small number of unique and interesting expeditions to the Andes and Latin America. Many of these are First Ascents and other exploratory expeditions. The majority of these are led by John Biggar in person, with one or two selected trips being led or co-led by other qualified and experienced leaders.

Climbing & Ski Mountaineering Instruction & Guiding

In addition to the scheduled expeditions and courses that john Biggar/ANDES organise, we can organise instructional courses, expeditions and straightforward ski-touring trips in many diverse parts of the world.

Scottish Climbing Instruction (opens in website)

John Biggar can also instruct winter climbing, scrambling, rock climbing and ski-mountaineering in all parts of Scotland. In the past I've run winter skills and ski-touring weekends, week long winter courses and guided ascents of classic rock climbs for individuals, families, Mountain Rescue Teams and clubs.
