A beginner mountaineering course in Chamonix takes you from no experience to competent on glaciated terrain. Most run over two or three days with an IFMGA guide, and while every guide teaches it slightly differently, the ground covered is much the same.
Moving on snow and ice. You'll learn to walk in crampons properly — flat-footing across moderate ground, front-pointing where it steepens, and switching between the two without breaking rhythm. Alongside that comes the ice axe: how to carry it, how to use it as a self-belay on a slope, and how to stop yourself when you slip. Self-arrest is practised deliberately and repeatedly, in every position you might fall in, until it stops being something you think about.
Rope work. You'll cover the knots that matter and when each one is used, then tying into a glacier rope team — spacing, pace, and keeping the rope taut without pulling your partner off balance. Most courses also cover belaying and abseiling, since both carry over onto the rock and mixed ground you'll meet later.
Reading a glacier. Where crevasses tend to run, what a weak snow bridge looks like from above, and why the most direct line is often the wrong one. Guides give this real attention, because route choice prevents far more incidents than rescue skill resolves.
Anchors and crevasse rescue. Building snow bollards, deadman placements and ice screw anchors, then backing them up and testing them. From there the rescue sequence: holding the fall, transferring the load off your body onto the anchor, escaping the system, preparing the lip, and hauling. You'll also learn to prusik out under your own power, which is what you'll need if you go in with only one partner above you.
Judgement. Reading a forecast for freezing level, planning realistic timings, and setting a turnaround point before you're tired enough to talk yourself out of it.
Where this is taught depends on the programme, season and conditions. For teaching on a glacier, taking the Aiguille du Midi lift, Skyway or Montenvers are usually used. Some courses take you to a real mountaineering objective - often the Aiguille du Tour at 3,540m, which includes a night at a refuge.
