Here’s a Scottish mountain you probably haven’t heard of, located around 30 miles west of Ben Nevis, nuzzled up against a wild and ragged coastline. At 2,671 feet (814 m) high An Stac is only classed as a Corbett, but that underplays what this steep-sided rocky cone has to offer. Rough, virtually pathless, the views from its summit are some of Britain’s best. You’re surrounded on three sides by wave of wave of mainland mountains, while out to the west is the big pay-off, with coastal views stretching across the Isle of Eigg to the jagged peaks of Rum. And the best bit? You’ll probably have the place all to yourself.
