Stob Glas

The walk up Stob Glas from Arrochar is relentless but rewards you with proper views across the Loch Long valley. It's a Scottish peak that doesn't mess about - steep, boggy in places, and the sort of climb that leaves your legs knowing they've done something. Most walkers allow three to four hours return, depending on fitness and how often you stop to catch your breath.

The summit itself sits at just under 900 metres, which means you're high enough to feel like you've achieved something but not so exhausted you can't enjoy the vista. On a clear day the panorama spreads across Argyll - you'll see Loch Long stretching below and the surrounding hills rolling away toward the Trossachs. It's worth timing the climb for decent weather; on a clag day you're walking through cloud for most of it.

This is a proper hillwalker's mountain rather than a scenic stroll. Families with older kids who don't mind a slog will manage it fine, but young children or anyone after an easy leg-stretch should look elsewhere. The trail starts from the southern end of Arrochar village and the ground is unrelenting from start to finish.

If you're based at Beinglas Campsite nearby, this makes a solid day out. Pair it with time exploring the village itself or walking the lower trails around Loch Lomond, which sits just a few miles south. The climb itself is free - this is mountain territory, after all - and the campsite offers decent facilities if you're planning a longer Scottish Lowlands trip.
