Kilroom (St Thomas' Bay)

The ruins of St Thomas' Bay sit on the Pembrokeshire coast near Milford Haven, and they're worth the scramble down if you're already exploring this stretch of Wales. What remains of Kilroom - an old church and associated structures - tells a quieter story than the dramatic clifftop landmarks further east. The setting itself is the real draw: a raw, windswept corner where the bay opens up and you can see why someone decided to build here, centuries ago.

It's not a manicured heritage site. You'll find weathered stone, overgrown patches, and the kind of coastal erosion that reminds you these places are still changing. History buffs will get more from it than casual day-trippers - the sense of religious settlement in an isolated spot matters more than the physical remains themselves. Families with restless kids might find it brief; walkers and photographers tend to linger longer, especially when the light hits the bay properly.

There's no visitor centre or facilities, so come prepared. It's accessible year-round, though winter storms can make the approach dicey. Allow thirty minutes to an hour if you're taking photographs. Several of the local holiday parks - Eco Escape Campsite and Point Farm Campsite sit just three miles away - make decent bases for exploring this corner of the coast. Pair it with walks along the Pembrokeshire Coast Path rather than treating it as a destination in itself. The real magic is in the walk there and the exposure of the place, not the ruins alone.
