Byrgwm

The hill fort at Byrgwm sits above Carmarthen like something the landscape forgot to finish. You're looking at Iron Age defensive earthworks - concentric rings of banks and ditches that once made this a proper stronghold. The views across Carmarthenshire from up here are the real reason to come, mind. On a clear day you can see right across the valleys.

It's not a manicured heritage site. There are no information boards, no café, no paved paths. You're basically wandering around someone's hillside looking at bumps in the ground. That's actually fine if you know what you're looking at - the ramparts are still quite distinct if you've got any interest in Iron Age settlement patterns. Families with restless children might find it a bit thin on entertainment value.

Walkers will get more from it. The approach itself is a decent trek from Carmarthen, and the hill demands proper boots if it's been wet. Allow an hour to walk the perimeter and take in the views properly. There's no obvious way to charge for it - it's just land. Worth combining with Glynmarch Farm Camping or one of the other glamping spots around here if you're staying locally, turning it into part of a broader rambling day rather than a dedicated trip.
