Carmarthen, UK Guide: Things to Do, Day Trips & More

Unless you’re from around Carmarthenshire or Wales, it’s likely that you’ve never heard of Carmarthen. But Carmarthen not only has an impressive history but still has lots of things to do and see, along with being surrounded by several interesting places near it.

Carmarthen is the oldest continuously occupied town in Wales, which means it’s been around for much of the country’s history. It has ties to the ancient Romans, Arthurian legends and rich national history.

Because of its importance throughout history, Carmarthen is still a thriving town with lots of things to do. Here they are, along with things to do outside of town on a day trip.

1. Explore Carmarthen Castle

Carmarthen Castle isn’t particularly impressive nowadays, as time and history weren’t kind to it. Once one of the most important and impressive castles, there isn’t much left of this castle ruin.

But it’s fascinating to explore, and it’s an iconic part of Carmarthen, tucked away in between the more modern buildings that arose around it. While it’s not a museum, there are many informational signs throughout where you can learn more about it, and best of all, it’s free to enter!

2. Enjoy people watching at Cofio Lounge

Located in the beautiful Carmarthen Guildhall, Cofio Lounge is a great place to go on a sunny day in particular. They have outdoor seating on the square where there’s often lots of activity, and so it’s perhaps the best place in Carmarthen if you want to eat or drink outside.

3. Standing Stones at Carmarthen Park

These may look like an ancient standing stone circle, but unfortunately, they’re not ancient. It’s still a cool place to hang out. Grab something to sip on from the Tea Shop located within the park while you enjoy the stones.

4. Take a walk through the Morfa Wetlands

For a bit of nature within walking distance of town center, the Morfa Wetlands are a great place for a stroll. You might luck out and see some wildlife too.

Make sure to stop by nearby Picton’s Monument and the row of colorful houses while you’re over there.

5. See the location of Merlin’s Oak Tree

It is said that Merlin the wizard was born in Carmarthen. I personally think the town is missing out on a huge tourist opportunity by not capitalizing on this fact. I mean, Merlin might be an even more famous wizard than Harry Potter!

There is one Merlin related thing you can see in town, although it’s easy to miss and there’s not much to see anyway: the location of Merlin’s oak. Legend has it that Merlin prophesized that when the oak tree fell, “then shall fall Carmarthen Town.” This oak tree was a point of tourist interest for centuries as a result.

Well, the tree isn’t there anymore, having been cut down in the 1978 to make room for car traffic (to be fair though, the tree was already dead by then anyway). You can still see the location (on Priory Street) and there’s an informational plaque nearby where you can read more about it. And there is a piece of tree located in the Carmarthenshire County Museum.

6. Explore the town’s Roman ties at Amphitheatre Moridunum

Amphitheatre Moridunum is one of the few Roman amphitheaters in Britain. There isn’t a whole lot to see here today, but you can use your imagination to see how impressive it once was!

It’s a grassy area and a nice quiet place to chill for a bit while looking at the remains of human activity from almost two thousand years ago.

7. Go Geocaching to see the area

This is such a great way to explore a place. Carmarthen was the first place I ever tried geocaching, and I had a lot of fun doing it! If you have time, check out the ones located outside of town. And while you’re out wandering Carmarthen, make sure to read the numerous informational signs throughout the town. It’s the best way to learn more about Carmarthen’s history.

8. Rock climb in an old church at Overhang Centre

This is definitely the most unique place you’ll going rock climbing. It’s located in a gorgeous old church, and the high roof makes for an excellent rock climbing center. If you’re not going with kids, I’d recommend going on a Friday night when they have adult socials. There is a discounted entry fee and shoe rentals are free.

9. Go shopping at both big chains and small boutiques

One of the best things to do in Carmarthen is to go shopping. It’s full of big brand name shops on St. Catherine’s Walk, so head there for the best shopping. And you’ll also find a sprinkle of boutique and local shops throughout town as well.

There is also an outdoor market on Wednesdays and Saturdays, as well as an indoor market with a variety of wares being sold there from crafts to antiques to clothing to food.

10. Take a walk along the River Tywi

The path along the river is pretty well maintained and the landscape is quite green and pretty all throughout the year. It’s a very peaceful walk that makes you forget you’re near a big, bustling town.

Day Trips from Carmarthen

Carmarthen is the county town of Carmarthenshire, which has lots to do. Here are some places nearest to Carmarthen that I think are worth a stop when you’re in the area.

Gwili Steam Train

If you’re into historic steam trains and would like to support their continued service, take a ride on Gwili Steam Train. You won’t be going anywhere of particular interest on this train, and it’s a roundtrip journey, but the green scenery of forests, hills and countryside you’ll see outside the windows will make for a calming ride.

They have special themed rides throughout the year (I went on the Halloween one) and you can also book a train ride that includes cream tea served onboard.

Llansteffan

This nearby town (about 15-minute drive) is great if you’d like to escape the bustle of Carmarthen but still have some things to do. The castle ruins here are much bigger than those left in Carmarthen, and you can enjoy a beautiful view from here. Located below the castle is a beach, and it’s a great place for a walk. The town itself is very peaceful, and I recommend Inn At The Sticks for a meal.

Laugharne

A tiny bit further is Laugharne, a town famous for its ties to the poet Dylan Thomas and other literary figures. It’s a beautiful little town with an impressive castle and lots of peaceful walks.

National Wool Museum

A bit further away from Carmarthen, it’s still only half an hour drive and one of the best things to do in the area if you’re interested in Wales’s wool industry. If you haven’t noticed, there are many, many sheep in Wales, so this was a huge industry.

National Botanic Garden of Wales

One of the best things to do on a day trip from Carmarthen is to visit the National Botanic Garden. Not only are the gardens beautiful and big, but you can also visit the birds of prey center here too.

Pembrokeshire

Carmarthen is also located right next door to Pembrokeshire, a region which contains the UK’s only coastal national park, rich history and beautiful castles. You can very easily access the very best that Pembrokeshire has to offer from Carmarthen.
