An Cruachan

Ben Cruachan rises 3,689 feet above Argyll like a proper mountain should - steep, imposing, and absolutely worth the effort if you're fit enough for it. The ascent from the A85 near Colintraive takes most people between four and five hours return, depending on fitness and how many times you stop to catch your breath. The views from the top sprawl across the Firth of Lorn and into the Highlands beyond, which on a clear day justify every punishing step.

This is a peak for serious walkers, not a casual family stroll. The terrain is rough and exposed higher up, and the weather can turn vicious in minutes - bring proper kit and don't underestimate it. Children will manage it if they're experienced hill-goers, but younger kids or casual rambler types will find it grim. The lower slopes can be muddy and boggy whatever the season.

What makes Cruachan special is its position between the lochs and glens of Argyll, giving you something genuinely wild without needing to trek to the far northwest. The Cruachan Visitor Centre sits at the foot if you want to learn about the hydro scheme, though the mountain itself is the real draw.

If you're based at Glendaruel or Strathlachlan Caravan Parks nearby, this is the obvious day out - challenging enough to feel like a proper achievement. Loch Eck Caravan Park puts you within striking distance too. Early starts are essential; afternoon weather deterioration is a real risk.
