About Troisgeach
Rising above the remote head of Glengyle, this quiet Tump offers a rugged, pathless ascent typical of the Trossachs interior. From its 733m summit, hikers earn an exceptional perspective down the silver length of Loch Katrine, with the jagged skyline of the Arrochar Alps—specifically Ben Vorlich and Ben Vane—dominating the western horizon.

Did You Know?
- •The name is likely derived from the Gaelic 'Treisgeach', which translates to 'parched' or 'shrivelled,' often a reference to the quality of the grazing land on its upper slopes compared to the lusher glens below.
- •The hill occupies a significant position on the watershed between the Loch Lomond and Loch Katrine catchments, effectively acting as a bridge between the Arrochar Alps and the Trossachs.
- •While it lacks the status of the nearby Crianlarich Munros, its summit provides a uniquely clear, close-up view of the distinctive 'notched' summit ridge of Beinn a' Chroin to the north.
- •The approach from Inversnaid requires navigating the rough, often boggy terrain of the Snaid Burn, a stark contrast to the well-trodden West Highland Way nearby.
- •If you encounter another person on the slopes of Troisgeach, they are almost certainly lost, or an extremely dedicated hill-bagger looking for a quiet afternoon.
