Lawrenny Castle

Crumbling stone walls rise from the banks of the Cleddau estuary like broken teeth, all that remains of what was once a formidable 13th-century fortress. Lawrenny Castle sits on a dramatic promontory overlooking the tidal waters, and while there's not much left standing, the setting is absolutely spectacular. The ruins are modest - a few walls, some foundation stones, and the ghost of a gatehouse - but the location more than makes up for what time has taken away.

History buffs will appreciate the castle's strategic position guarding the estuary, though children might find the scattered stones less thrilling than promised. The real draw here is the walk itself and those sweeping water views across to the Pembrokeshire hills. It's a proper peaceful spot, especially at high tide when the estuary is full.

Getting there involves a pleasant stroll from Lawrenny village, though the path can be muddy after rain. There's no entrance fee or opening hours - it's just there, open to the elements as it has been for centuries. Allow an hour for the walk and a good poke around the ruins. From holiday parks like Oaklea Glamping or Hungerford Farm near Narberth, it makes a decent half-day trip combined with a pub lunch in the village.
