This is a beautiful little hill with a trig pointed summit, great views out over the Pembrokeshire coastline, and an Iron Age fort. There is also a great car park at the bottom of the hill and a good footpath to its rocky top. A 20 minute trip will see you up and down. It was cold today, but on a sunny day it would be a heavenly picnic spot.

This beach is made up of pebbles and exceptionally dark sand made from crushed grey slate. The slate gives the water in the "Blue Lagoon" its bright deep blue colour. To the north of the beach is a lovely little harbour - an open-cut quarry that is also wheelchair accessible. Be careful: there are strong currents here.

Carreg Samson, a dolmen, lies over Abercastle Bay, near Fishguard. The capstone is approximately 4 1/2 m long and 2.7 m wide. It lies on three of the seven upright support stones. The dolmen was previously covered by a mound of earth or stone. At the beginning of the 20th century, the gaps between the stones were closed so that the dolmen could be used as a sheepfold. The Carreg Samson is a so-called Scheduled Monument.

It doesn't matter whether it's a bright blue sky and a wide view or stormy clouds - enchantingly beautiful. And not only from close by but from many cliffs from afar.
