The Alps in winter are transformed. Fresh snow has a cleansing effect and the mountains often seem at their best under its mantle. Cold temperatures and a reliable snowfall ensure excellent climbing conditions. Ice (or cascade) climbing is a great adventure! There’s nothing like hanging from your tools on a magnificent frozen waterfall or smear. The experience of climbing cascades varies from one to another and year to year. It really is an ephemeral experience.
The Alps and Norway have an abundance of icefalls which regularly come into condition from December to February. Stable conditions means you can achieve a lot and approaches can be anything from a couple of hours to roadside. The high mountains can also be in superb condition during the winter and into spring. By using uplift, skis or snow shoes and perhaps refuges the classic couloirs and north faces are achievable.
