Carmarthen Highlights: Things to See and Do in Carmarthen

Carmarthen Castle

Carmarthen Castle, located right in the centre of town, is a must-visit for history enthusiasts. Though much of the original structure has faded over the centuries, the surviving remains offer a glimpse into Carmarthen’s Norman and medieval past. The castle walls and gatehouse are particularly striking, and the site includes an interactive heritage centre. Entry is free, and it’s worth spending some time reading the plaques and displays that tell the story of the town’s development.

The Old Market and Carmarthen Indoor Market

The town’s bustling indoor market is a focal point of local life. Set within a modern glass-roofed hall, the market hosts a range of vendors selling everything from Welsh cakes and artisan cheeses to antiques, clothing, and crafts. It's open Monday to Saturday and is the perfect place to try local produce or pick up a unique souvenir. Outside, on certain days, you’ll find a traditional outdoor market in Nott Square, adding to the town’s old-world feel.

Oriel Myrddin Gallery

For a dose of culture, Oriel Myrddin Gallery is Carmarthen’s leading art venue, showcasing contemporary Welsh and international artists. Housed in a lovely Victorian building, the gallery is small but thoughtfully curated, and regularly features exhibitions of ceramics, textiles, and visual art. There's also a charming little shop selling handmade gifts and artworks by local makers.

Merlin's Hill and Merlin's Oak

Carmarthen is deeply entwined with the legend of Merlin, the mythical wizard from Arthurian tales. A short drive east of the town centre brings you to Merlin’s Hill, believed to be his final resting place. A local farm offers guided tours with insights into the legend, as well as lovely walks with panoramic views of the Towy Valley.

In the town itself, you’ll find a plaque marking the site of Merlin’s Oak—once a mighty tree said to be cursed. Though the original oak is no longer standing, the story remains a key part of Carmarthen’s identity. Legend claims that disaster would befall the town if the tree was ever removed… and local lore says it was cut down shortly before a great flood in the 1970s.

Carmarthenshire County Museum

Located just outside the town in the grounds of an old bishop’s palace, the Carmarthenshire County Museum offers a fascinating look at the area’s history. Exhibits include Roman artefacts, Welsh textiles, agricultural tools, and displays on Carmarthen’s role in the Reformation. The museum sits in beautiful grounds, making it a peaceful place to spend a morning.

The Gwili Railway

Just a few miles from town, the Gwili Railway is a heritage steam railway that offers a nostalgic trip through the stunning Carmarthenshire countryside. Operating on a restored section of the former Carmarthen to Aberystwyth line, the railway is popular with families and rail enthusiasts alike. The journey runs along the scenic Gwili River and offers special events like cream tea rides, murder mystery evenings, and Santa trains at Christmas.

Carmarthen Park and Velodrome

Carmarthen Park is a leafy green space ideal for a relaxing walk or a picnic. The park is also home to the Carmarthen Velodrome, one of the oldest outdoor cycling tracks in the world still in use. It’s a great place for children to let off steam, with a playground, walking trails, and summer bandstand concerts.

Aberglasney Gardens

Roughly 20 minutes from Carmarthen, Aberglasney is one of Wales's most beautiful historic gardens. The site features a restored Elizabethan cloister garden, formal borders, woodland walks, and a walled garden. It’s a tranquil, picturesque escape, and the on-site tearoom is a lovely spot for lunch or cake.

National Botanic Garden of Wales

Only a 25-minute drive from the town, the National Botanic Garden of Wales near Llanarthne is an essential day trip for nature lovers. It features the largest single-span glasshouse in the world, housing Mediterranean and exotic plants, alongside vast outdoor gardens, meadows, and lakes. It also hosts regular events, from gardening workshops to wildlife weekends.

Laugharne

While not technically part of Carmarthen itself, the nearby coastal town of Laugharne—just half an hour’s drive away—is closely tied to the area. It's famously home to the poet Dylan Thomas, whose writing shed and boathouse can be visited. Laugharne Castle, overlooking the Taf Estuary, adds to the atmosphere.
