Castell Bach

Stone foundations scattered across a windswept hilltop tell the story of an Iron Age settlement that once commanded sweeping views over Cardigan Bay. Castell Bach - literally 'small castle' in Welsh - isn't much to look at from ground level, but climb up and you'll appreciate why our ancestors chose this spot.

The earthworks and partial stone walls that remain hint at a fortified enclosure, though don't expect towering ruins or information boards. This is archaeology in its rawest form - lumps and bumps in the landscape that require imagination to bring alive. History enthusiasts who enjoy piecing together the past will find it fascinating, while kids might lose interest after ten minutes unless you spin them a good tale about ancient warriors.

Reaching the site involves a proper walk from Llanrhystud, so wear decent boots and allow an hour each way. The views alone make it worthwhile - on clear days you can see right across the bay. There's no admission fee because there's nobody here to collect one, and no set opening hours because it's just a field with old stones.

If you're staying at one of the holiday parks near Llanrhystud like Pengarreg or Morfa Farm, it makes a decent morning expedition for those who fancy stretching their legs and getting away from the crowds.
