The traverse of An Teallach provides on of the two best ridge walks in the Highlands of Scotland - and the competition's pretty hot.
The walk also includes an outstanding Corrie Loch [Coire for Scottish members!] Loch Toll an Lochain.
Do treat the warnings in the website seriously - this is not a stroll for first-timers! -to put it mildly, but the scenery is superb.
