Perhaps not the most spectacular of Pembrokeshire's castles, Nevern castle is still worth including on your route. It's located high above the Nant Gamman stream with a steep natural gorge on one side and commanding views over the landscape. The remains of the motte and bailey castle probably date to Norman times, but it's thought this has been a defended position since the Iron Age some 2,000 years ago.

Ceibwr is a gorgeous little bay towards the northern end of the Pembrokeshire Coast Path. The rocky coastline around Ceibwr is wild and dramatic, with many instances of impressive rock scenery. The bay itself is steep sided and was carved in the last Ice Age by surging meltwater forcing its way through what is now the Cwm Trewyddel valley. It's a great spot for wildlife watching. Grey seals can be spotted close by, while porpoises are often sighted offshore.

A brilliant walk along the cliffs to reach this place, do be mindful as some of the paths to get to it can get close to the cliff edges. However, once there we had the place to ourselves which gave us plenty of time to explore. Well worth a visit.

The cavernous pool is called Witches Cauldron (Pwll-y-Wrach in Welsh) due to its peculiar green water. Set on a beautiful part of the Pembrokeshire Coast Path, you'll find this spot to be surprisingly quiet, considering how picturesque the landscape is. Access is very steep and walking boots are essential.
