Mor Dearg Arrete, and further North on the Torridon giants of Liathach, Beinn Eighe and Beinn Alligin.
In the Cairngorms there are the Arctic fastnesses of Ben Macdui, Ben Avon and Cairn Toul. Some sections of the fabled Skye Ridge are accessible for those with no climbing skills. And then there are long and spectacular trails through the mountains such as the Lairig Ghru and the route through Glen Affric goes into the remnants of the ancient Caledonian Pine Forest that once covered much of the Highlands.
All in all the beautiful and changing winter landscape of Scotland has a lifetime of challenges.
