It seems rare to be in Wales amongst the mountains on a sunny day! So it was wonderful that the sun shone on the hike to Corn Du and Pen y Fan, the highest mountain in the South of the UK. What’s more, this must be the most comfortable hike to 886m I’m likely to do. That probably explains why there was a human snake wriggling it’s way up to the top consisting of young, old, and families with pushchairs!
