Dylan Thomas Boathouse
The pretty town of Laugharne, on the estuary of the River Taf, was home to one of our most famous writers, Dylan Thomas. Laugharne was thought to be the inspiration for his best known play, Under Milk Wood. There are lots of sites associated with him here.
He wrote his work Portrait of the Artist as a Young Dog in the castle summerhouse with its sweeping views across the Taf estuary. And the Boathouse, where he lived with his wife Caitlin and their children has been left almost untouched and his writing shed in the garden still has his notes scattered on the desk. You really get the feeling he's just stepped out for a drink at Brown's Hotel, his favourite drinking haunt, just a short walk away in the village.

Plas Llanelly House
A handsome example of a Georgian-era mansion, Plas Llanelly House is situated right in the centre of Llanelli. Delve into the past on a guided tour; many rooms are furnished just as they would have been centuries ago. You'll learn about the lives of Sir Thomas and Lady Stepney who lived here in the 18th century, and then continue on to the Victorian era. There are tales of scandal and of spooky encounters aplenty.
Once you've taken in the architecture, interiors and atmosphere, treat yourself to a bite or a cuppa in the café. For something more substantial, the restaurant serves locally sourced and Welsh inspired dishes.
The National Wool Museum
Wool was historically the most important and widespread of Welsh industries and the craftsmanship associated with shawls, blankets and bedcovers manufactured in Wales is known the world over. The National Wool Museum is located in the former Cambrian Mills which made woollen clothes and furnishings that were exported all over the world.
A visit to the museum allows you to trace the wool's journey from fleece to fabric in these attractively restored listed mill buildings. The museum houses all sorts of historic machinery used in the woollen mills and a raised walkway gives you a great view of textiles still in production at Melin Teifi, the site's commercial woollen mill.

Dolaucothi Gold Mines
The Romans discovered there was gold in the rocks here some 2,000 years ago and mining for this most precious of metals continued until the 1930s. The Dolaucothi Gold Mines tour traces the evolution of mining in Carmarthenshire down the centuries from those simple early Roman digs and leads you through the underground mines in the process. You wear a hard hat and there are some sections of quite steep steps to negotiate. Once you've finished you can try panning for gold yourself. Whilst there isn't a café here, there is a nice picnic area so why not bring a packed lunch?

You can also explore the diverse habitats across the 800 acre estate, with wildlife including the park's rare-breed White Park cattle, fallow deer, birds, butterflies and trees - some of which are 700 years old! Alongside, the moody ruins of Dinefwr castle sit up on a hill overlooking the River Tywi. It features ditches cut from solid rock to form its moat, a massy round tower and walkways along the tops of short sections of wall.

Castles in Carmarthenshire
Wales has more castles per square mile than any other country - over 400 in total! So it's no surprise Carmarthenshire has ruins aplenty.
Another set of splendid ruins on top of a massive lump of granite, Carreg Cennan is often photographed from afar with whisps of mist in the valleys surrounding it. As well as ancient ruins to explore here, there's a remarkable underground cave deep down in the rock under the castle. Make sure to take a torch and take care on the slippery steps!
Kidwelly Castle in the pretty town of the same name is one of the best preserved castles in Carmarthenshire. The original Norman castle of earth and wood dates back to the 12th century whilst the impressive stone structure still standing is just 600 or so years old! Film buffs may recognise Kidwelly from a fleeting appearance at the beginning of Monty Python & The Holy Grail.
The location of Llansteffan castle is perfect. You'll be wowed by the amazing views across Carmarthen Bay and the Tywi Estuary, as well as the surrounding rolling farmlands. A winding climb uphill brings you to the gatehouse with its imposing archway, mighty towers and extensive remains of the craggy walls. Climb up inside for the best views.
This was once one of the largest castles in Wales, built by Norman King Henry I. These days the massy gatehouse and parts of two towers and walls remain. Take a wander around the walls and climb up inside for views across the town and the river Tywi.
The moody ruins of Dryslwyn Castle sit on top of an abrupt rocky outcrop overlooking the Tywi valley. The fortifications here owe their origins to one of the Welsh princes of Deheubarth, the kingdom in south-west Wales. Today a small section of the middle and outer walls remain, but the views after the steep climb up are what make the trip really worthwhile.
