Blaen Hafren

The source of the River Severn sits up in the Powys hills, about six miles from Llanidloes, and it's one of those places that feels properly remote despite being relatively accessible. Blaen Hafren is essentially a marker - a small stone and a bit of fencing - at the point where Wales' longest river begins its journey toward England and the sea.

What makes the trek worthwhile isn't the destination itself so much as the walk to get there. The moorland setting rewards you with real solitude and wide views across Mid Wales. On a clear day you understand why people bothered to walk this far just to stand at the start of something. It takes the best part of an hour to reach from the nearest car park, so come prepared for variable weather - this is upland terrain and it shifts fast.

Walkers and geography enthusiasts will absolutely get it. Kids might find it underwhelming unless they're already keen on natural features and the satisfaction of reaching a 'source'. There's no visitor infrastructure at all, which means no crowds and no faffing about with entry fees.

If you're staying at Glangwy Farm Camping near Llanidloes - and it's a decent spot with proper facilities - this makes a solid half-day outing. Pair it with a proper walk through the Hafren Forest nearby. The whole valley has that quiet, unspoilt character that makes Mid Wales worth the drive. Go early to avoid what little traffic these hills get.
