In reply to petre:
Forcan Ridge, II, is an excellent winter mountaineering route - a very long inescapable ridge with one unavoidable ab. Its a long day so give yourself the maximum time possible and start at dawn. Quite a long and steep walk in along a good path, long sustained route although nothing too technical except for the slabs which you can avoid on the left, descent can be tricky in poor weather and potentially avalanche prone so prep up on this beforehand. Well worth it!!!
