How to climb Ben Lomond (tourist path up, Ptarmigan Ridge down)

Covering 720 square miles, 22 lochs and 21 Munros, Loch Lomond and the Trossachs National Park is famous worldwide for scenery and outdoor adventure. And if you want the very best introduction to the park, climbing Ben Lomond is hard to beat.

Start Point: Rowardennan Car Park – most walkers start from the Forestry Commission car park at Rowardennan, on the eastern shore of Loch Lomond. On a good day it fills up quickly, so arrive early if you can. There’s usually a small parking charge, and basic facilities nearby.

The route up: – the ‘tourist path’ is well-made and easy to follow, but don’t be fooled – it’s still a steady, relentless climb. As you leave the tree line behind, the views open up spectacularly over Loch Lomond and its many islands.

The summit plateau & final push – eventually, the path levels out onto a broad plateau, a welcome place for a well-earned rest before the final pull to the summit.

Descending via the Ptarmigan Ridge – if the ascent is about endurance, the Ptarmigan Ridge descent is all about enjoyment. For me, this ridge walk tops almost every other descent I’ve done in Scotland. The views back across Loch Lomond are absolutely stunning.
