The Tywi Valley, Carmarthenshire

The Tywi Valley

YOU ARE HERE:   HOME   THE TYWI VALLEY

One of the most picturesque valleys in Wales

The Tywi valley follows the path of the River Tywi from its source in the Cambrian Mountains to its meeting with the sea at Carmarthen Bay, gently weaving its way through some 35 miles of beautiful Carmarthenshire scenery.

Meandering gently through this stunning countryside, the river Tywi flows through picturesque meadows and ancient woodlands flanked by gently rolling hillsides and a patchwork of medieval farmlands.

In the 11th and 12th centuries the Normans fortified the landscape with castles at Carmarthen, Dryslwyn, Dinefwr, Carreg Cennen and Llandovery, the Tywi being once a medieval battleground for Welsh princes and English kings. During Roman times the area became a strategic supply route between Carmarthen and Llandovery, Roman Amphitheatre remains can be seen at Priory Street in Carmarthen (one of only seven sites in the UK).

The breathtaking scenery of the valley offers inspiration for walkers, cyclists, artists and photographers and is rich in flora and fauna, look out for otters, herons, the red kite and many rare plants thriving along the river banks. The National Botanic Garden of Wales and Aberglasney Gardens are located in the heart of the valley making this area one of Wales's foremost horticultural destinations.
