Cnap Mor

The walk up Cnap Mor from Arrochar is a proper hill scramble rather than a gentle stroll - steep enough to make your legs work, but short enough that you're not committing to a full day in the mountains. You'll climb roughly 380 metres through mixed terrain, picking your way over rocky sections and heather moorland until you hit the summit, where the views across Loch Long and toward Ben Arthur are genuinely striking.

It's the sort of peak that appeals to walkers who want a real challenge without needing technical climbing skills or ropes. Families with older children who don't mind a bit of scrambling will find it rewarding, though younger kids might struggle with the steeper pitches. Allow a solid two to three hours for the round trip depending on your fitness.

The beauty of this one is its proximity to Arrochar, which means you're not wrestling with a two-hour drive to reach the trailhead. Start early if you can - the weather can turn quickly on these hills, and afternoon mist creeping up from the loch happens more often than not. Fair-weather days only, really.

If you're based at Beinglas Campsite just down the road, this becomes an excellent half-day adventure that leaves your afternoon free to potter around Loch Lomond itself. Loch Lomond Holiday Park, a bit further afield, would make a reasonable base too if you're combining it with other walks in the area.
