Schiehallion

Schiehallion is a mountain in Perth and Kinross rising to about 1083 meters with a pointed summit when viewed from the west. From the north and south, it displays a distinctive elongated ridge that gives it a completely different appearance.

The mountain served in the 18th century as a testing ground for measuring Earth's mass through gravitational experiments. These studies advanced cartographic techniques and contributed to understanding the planet's physical properties.

The Gaelic name Sidh Chailleann means Fairy Hill of the Caledonians, connecting this place to Scottish Highland tradition and local stories. The mountain appears in regional folklore as a site tied to the natural and spiritual landscape of the area.

The main hiking route starts from Braes of Foss car park and covers approximately 10 kilometers with about 750 meters of elevation gain. The path is well-established and clearly marked, though sturdy footwear and reasonable fitness help with the ascent.

Limestone formations on the western shoulder support specialized plant communities that survive from when Scotland bordered an ancient shallow sea. These rare plants grow nowhere else in the immediate region and offer a glimpse into the area's geological past.
