Cruach Tairbeirt
Cruach Tairbeirt — the isthmus stack — rises to 415m above Arrochar at NN 312 058, between Loch Long and Loch Lomond on the narrow neck of land that gives Tarbet its name. Vikings reputedly dragged longships across this isthmus in 1263. The summit looks straight across to the Cobbler and along Loch Long towards the Clyde.

Standard route
heather moorland 60% · grass slopes 30% · rocky summit 10%
Begin at the small car park beside Arrochar & Tarbet railway station. A waymarked forest path climbs north-west on a zig-zag through Sitka spruce to a clearing on the south ridge, then follows a clear path north along the open crest to the summit cairn.
Terrain
Stone-cobbled forest path through the lower spruce, then a peaty open ridge with occasional duckboards laid by the National Park rangers. The summit is short turf and bare schist with a small cairn.
In winter
Damp west-coast hill where ice forms on the wooden boardwalks under the forest canopy. Snow on the open ridge is wet and patchy. Microspikes useful on the path; the open ridge is rarely an issue.
