Get into the Mountains
Skye is famous for its mountains, especially the Black Cuillin. These are the remains of volcanic eruptions some 60 million years ago. The rock is wonderfully grippy black gabbro, often dissected by smooth red basalt intrusions that sometimes form wonderful staircase-like features.
Most walks into the Black Cuillin are quite challenging, and should only be attempted by confident and properly equipped walkers. At the more amenable end are walks into the Fionn Coire from either Glen Sligachan at NG483958, or a shorter walk from the Fairy Pools car park.
From the coire it is possible to climb the munro of Bruach na Frith following a clear but loose path South to the bealach, then turn right to the summit at 958m. The views along the rest of the ridge and beyond are breathtaking.
