Route 4 - South Pembrokeshire

Firstly we head as far west as we can get without getting wet! So it's a fast sprint to Haverfordwest, then a slower loop of St Brides Bay on our way to Pembroke and its pretty castle.

From here we skirt the scenic coastline to the popular resort of Tenby, with its pastel shaded houses and picturesque harbour.

The coast road delivers us next to Pendine Sands, scene of many land speed world records, with its 7 mile beach and museum of Speed.

Across the peninsula we hit Laugharne, where the great Dylan Thomas wrote some of his famous works.

Returning via Carmarthen, if daylight allows we'll turn south through the Gwendraith Valley, rounding the Burry inlet and it's cockle beds before crossing the Lougher estuary and then home.
