My family is from Wales, and I headed down there for my grandfather's 90th birthday. While there, my dad suggested that we hike up Pen Y Fan, a very big mountain in Brecon that he'd always wanted to walk up.
It was a tough walk, through fog and up steep rocky paths. But we made it, and it was beautiful!
We also had a more civilised day visiting Tredegar House in Newport - as you can see, it was much better weather!
