Classic 4000ers

Our Classic 4000ers offers you the opportunity to tick off some of those 4000m peaks that you've not climbed before. Flexible to go anywhere in the Alps, we operate on low ratios and take into account what peaks you've climbed before.

Classic Alpine Ascents

A guided week of classic alpine mountaineering dedicated to achieving some great alpine climbs and summits, without being restricted to attempting only 4000m summits.

Monte Rosa 4000ers

At the head of the Zermatt valley a huge wall of 4000m peaks, the Monte Rosa Chain, extends from the Breithorn all the way across to the multiple summits of Monte Rosa.

Bernese Oberland 4000ers

The peaks of the Bernese Oberland form the northern rampart of the Swiss Alps. They have a wilder and more remote feel than the Swiss Valais, with more snowfall, bigger glaciers and fewer mountain huts.

Guided Climbing weeks - Level 3

Technical 4000ers

The Alps is an incredible playground of rock features and snowy summits and on this course we challenge ourselves on the more technical and adventurous 4000m peaks.

Technical Alpine Rock

An adventurous and challenging week of technical alpine rock climbing in both the Swiss Valais and further east of the Bernese Oberland.

Technical Alpine Ascents

This week of technical mountaineering is not tied to any particular area or peaks. The course has a simple aim - to give participants a great week of challenging alpine climbing on the finest routes of at least two different alpine valleys of the Swiss Valais, Bernese Oberland or Mt Blanc Massif.

Private Guiding and Custom weeks

Matterhorn Ascent

Perhaps the most famous peak in the world after Everest, the Matterhorn is a superb summit demanding fitness, determination and a level of competence on both rock and ice.

Eiger Ascent

Thanks to its formidable North Wall, the Eiger (Ogre) is a world-famous summit and one of the alpine ‘big three’ alongside the Matterhorn and Mont Blanc. Forming the left edge of the North Face, the Mittellegi Ridge rises in imposing steps and towers to a knife-edge snow crest leading to the summit.

Please Note - we offer Private Guiding and Custom weeks to both individuals or groups of friends, that have specific goals and or objectives that they want to achieve anywhere in the Alps or further afield - please contact the ISM to discuss your plans.
