But which routes have had the highest ratings from users over the yeas? The results may surprise you….In fifth place is Cader Idris. No shocks here: this is a Welsh classic, a walk that you might expect to find even higher up the list. Arguably Wales’ most shapely hill, Cader Idris is likely to be in the top five of many walkers’ lists.

A hill that fails to top 200m barely counts as a day out; you could probably squeeze it in before breakfast. But stitch three of them together and it looks like more of a challenge. Throw in some sand dunes and one of the world’s top ten beaches and you have the ingredients for a mini classic. 

The only things required are a map, a backpack crammed with kit and food (and maybe some wine, if space allows) and a vague sense of which direction to start off in. With those essentials, the world is your oyster. Or the Brecon Beacons are, at least.
