Schiehallion

About Schiehallion

Rising as a near-perfect cone from the shores of Loch Rannoch, this iconic Munro offers a tale of two halves. The lower slopes feature a well-constructed path through heather, but the final ridge is a notorious boulder field of white quartzite, leading to a summit with views over the Tay Valley.

Did You Know?

• •The name derives from the Scottish Gaelic Sìth Chailleann, meaning the 'Fairy Hill of the Caledonians.' This suggests a long-standing cultural significance, with the mountain viewed as a mystical place by the ancient tribes of central Scotland.
• •In 1774, Astronomer Royal Nevil Maskelyne used the mountain's symmetrical shape for an experiment to 'weigh the world.' By measuring how the mass of the hill deflected a pendulum, he estimated the Earth's density. This project also led mathematician Charles Hutton to invent contour lines as a way to simplify the mountain's map data.
• •From the summit, the view west is dominated by the long stretch of Loch Rannoch leading toward the distant, jagged peaks of Glencoe. To the south, the massive bulk of the Ben Lawers range across Loch Tay provides a contrasting, broader silhouette.
• •The mountain is managed by the John Muir Trust, who undertook a massive restoration project in 2001 to repair a deep 'scar' visible from miles away. They moved thousands of tonnes of stone to create the current path, protecting the fragile high-altitude heath from the feet of thousands of annual walkers.
• •The upper ridge is composed of Dalradian quartzite. This hard, white rock does not weather into soil easily, which is why the final approach consists of an exhausting, trackless boulder field that can be surprisingly disorienting in mist.
• •Despite its appearance as a smooth, uniform cone from the road, the summit ridge is a chaotic jumble of quartzite designed to make even the most experienced walker question their footwear choices during the final half-mile.
