Diollaid Mhòr

The walk up Diollaid Mhòr is properly steep, and that's before you've even left the car park near Campbeltown. This 849-metre peak dominates the Kintyre Peninsula, and once you're up there, you understand why locals bother with the slog. The view sweeps across the Irish Sea toward the Mull of Kintyre, and on a clear day you can see all the way to the Scottish islands. It's not a technical climb - the path is well-worn and obvious - but the gradient doesn't ease off, so expect it to take the better part of two hours up and down.

Who should go? Serious walkers, mainly. Kids who are keen on hills will manage it, though younger ones might flag on the ascent. History buffs get little from this - it's purely about the landscape and that lung-busting sense of achievement. There's no visitor infrastructure at the top, no café, no shelter, so come prepared with weather gear and water.

The real appeal is how it slots into a Kintyre walking holiday. Carradale Bay Holiday Park sits only 2.4 miles away, making this a natural morning or afternoon mission from a static base. Muasdale Holiday Park, 5.9 miles distant, works too if you're staying that side of the peninsula. Allow three hours total, start early to catch decent light, and bring a windproof - the exposed summit catches Atlantic gusts that'll surprise you.
