January 11, 2025, Garn Fawr Summit and Trig Point

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.

A trig point with a lovely view. Nice place to sit half way around the Dinas headland loop and take in the scenery and have a break.

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.

October 14, 2023, Carreg Samson Dolmen

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.

Dinas Head on Dinas Island has a trig point at 142 m above the sea. The views along the coast in either direction are great, as is the Irish Sea in front of you. There is a nice coast path loop around Dinas Island with this as the highest point.

A rugged hill with an Iron Age hill fort on top of it. This vantage point offers views over the north Pembrokeshire coastline to the south west as well as views over Strumble Head to the north.

The steep climb (at least coming from the coast is rewarded with a magnificent view! We could see our entire loop from there. Wonderful!
