Backpacking Youtuber Liam Brown had planned just to walk the length of Snowdonia, north to south, but on a whim he decided to extend the journey all the way to Cardiff. Here's how he got on...

"I was uncomfortable with being comfortable" he says "so I packed my gear and made a plan."

"I had everything I needed in my pack... I'd wild camp in the best spots I could find each night. I'd aim to walk 20 miles a day, no more, no less. This was about experiencing life in a simple way."

Looks like a great trip - even when he resorts to two wheels!
