Having bagging the bulk of the Midlands Marilyns for last year’s challenge, I’ve set my sights on the short hop across the border to Cymru. Having been born in Cardiff, I always feel at home back in Wales and so any excuse to spend time exploring the wild landscapes, coasts, hills and mountains is always welcome.

Welsh Marilyns >450m

With 158 hills with a prominence of 150m or more, the Welsh Marilyn list isn’t to be underestimated. From minor hills and scramble peaks right up to the mammoth Yr Wyddfa (Snowdon) at 1085m, Wales has something to suit even the most avid of adventure seeker.
