Pembrokeshire is a lovely area and distances aren’t too far so you should be able to see quite a bit in your four days with a bit of careful planning.
If you are in the Cardiff area,
Cardiff Castle and the nearby fairy tale
Castell Coch are definitely worth visiting. They are a wonderful example of high Victorian Gothic work with their elaborately painted interiors. Seen from a distance. you can almost imagine Sleeping Beauty is still asleep in Castell Coch.
Between Cardiff and Manorbier is the lovely ruined
Carreg Cennan Castle set high on the hillside. Don’t miss the underground passageway running down the inside of the cliff face.
On the coast is the tiny village of
Laugharne which was the home of Dylan Thomas who used Laugharne for the setting of 'Under Milk Wood'.
Do try and visit the tiny city of St Davids with its
cathedral and
ruined bishop’s palace.
You can do a
boat trip to Ramsey Island from here, or even a whale and dolphin watching trip. The scenery seen from the sea is absolutely stunning.
Whitesands Beach is one of the most beautiful stretches of sand in Pembrokeshire.
If you like walking, the Pembrokeshire Coastal Path offers some very good walking. For a short walk, the stretch from Whitesands to St David’s Head is excellent as is the stretch from Porthgain to Arbereiddy.There are details of both of these
here.
June is a lovely time to do this as the coastal flowers will be at their best. It is almost like walking through someone’s private rock garden (sorry no photos as that was in our pre-digital days...)
