St Llonio Church (Llandinam Church)

You'll find this modest church tucked into the village of Llandinam, where the Severn Valley rolls out around you and sheep outnumber tourists by about a thousand to one. St Llonio's is exactly the sort of place that rewards a quiet wander - medieval stonework, a graveyard that tells stories going back centuries, and the kind of atmosphere you simply can't manufacture. The building itself is unpretentious: proper working church rather than museum piece, which is rather the point.

It's the sort of stop that appeals to walkers exploring the Powys countryside and anyone with a genuine interest in rural Welsh ecclesiastical history. You won't spend hours here - twenty minutes will take you through and round the churchyard - but that brevity is part of its charm. No gift shop, no entrance fees that I could find, no fuss.

If you're based at one of the nearby caravan parks - Gellidywyll, Love2Stay, or Maesmawr Farm Resort are all within easy striking distance - this makes a decent leg-stretch during a wider exploration of the valley. Combine it with a walk along the Severn or a potter through Llandinam village itself. Spring and summer are clearly the better bets weather-wise, though there's something rather appealing about visiting a church in autumn when the churchyard's quiet and proper atmospheric. Just check locally whether it's locked when you arrive, as these village churches don't always keep regular hours.
