Beinn Chaluim

The climb up Beinn Chaluim isn't exactly a walk in the park, but the payoff from the summit makes it worth every heavy leg. This 3,344-foot peak sits just outside Crianlarich in the Scottish Lowlands, and it's one of those mountains that looks innocent from the road before you realise what you've actually signed up for.

The walk takes roughly four to five hours round trip depending on your fitness and how much you stop for photos. The path itself is well-trodden but relentlessly steep in places - proper calf-burner stuff. What you get at the top, though, is genuinely spectacular: views sweep across to Ben More and Stobinian, and on a clear day you can pick out Loch Earn stretching away below.

This is for walkers with a bit of experience and proper boots. Kids might struggle with the sustained climb, and if you're after something gentler, the Lowland slopes around Tyndrum Holiday Park offer far easier rambles. But if you're staying in the area and you've got decent legs, Beinn Chaluim is absolutely worth the slog.

Go on a clear morning if you can - the weather changes fast up here, and cloud can roll in without warning. No facilities at the start, so sort yourself out in Crianlarich first. Free to climb, naturally. Allow a full afternoon and come back properly tired.
