What to do in Cardiff in one day

While talking about day trips from London, you might consider visiting Cardiff. Wales’ Capital it’s not always on the bucket list of travellers visiting the UK. However, instead of going through London, you should consider hopping on a train and within two hours, you will cross a border and enjoy a new culture. 

Visiting Cardiff in one day might be enough to enjoy the city centre and the beautiful Cardiff Bay. There is plenty of architecture, culture and scenery in such a small city.

We were fascinated by Cardiff, as not many suggest it as a destination, even for just a day trip. However, Cardiff with its beautiful architecture, the Victorian Arcades, the bay facing the Channel and the incredible landscapes, has impressed us a lot. To be honest it’s not a destination where we will spend more than a couple of days, but still worth a visit every now and then. Less chaotic than London, Cardiff should be part of your tour in the UK, along with Oxford, Cambridge, Manchester, York and others.

Stroll around the beautiful high street arcade

What was impressing us more about Cardiff, was the cute city centre. The old town was completely different from our usual landscape in London. The city, while it’s capital, has many city centres, which belong to the different areas. However, what we concentrated our attention on visiting Cardiff in one Day was the old town.

The city itself offers many opportunities to go and shop. The high street arcade it’s an insanely beautiful maze of six Victorian arcades, full of boutiques, bakeries, barbershops, lively bars and cute coffee shops. The tiled floor, the arcades and the architecture, make the Cardiff Shopping Arcade one of the most instagrammable spots in Cardiff.

However the high street arcade it’s not the only space to visit as a shopping mall. Within the “Castle Quarter”, the area surrounding the castle you can also visit the Duke Street Arcade and the Castle Arcade.

Enjoy the sunshine at Mermaid Quay

However the old town it’s not the only place to stroll around in Cardiff. The Mermaid Quay it’s the beautiful harbour nestled in Cardiff Bay. Visiting Cardiff in One Day you should consider splitting your time well between the part of the city surrounding the Castle and the seaside.

The Mermaid Quay it’s beautiful day and night and offers the perfect spot for a lovely stay in town. Around Mermaid Quay you can also find many beautiful hotels if you decide to stay overnight. This is the meeting point of locals, especially in spring and summer.

Have dinner at a beautiful restaurant by the sea

The Mermaid Quay it’s the perfect place to have a beautiful dinner by the sea. There is a wide choice of places where to eat in Cardiff Bay. Just walking around Bute Street, you will have plenty of restaurants, take away shops or just coffee shops for a bite on the go. 

At night the bay becomes so romantic, ideal for a dinner with your other half and a beautiful view. For a cheaper solution, you are served with Wetherspoon and many other pubs as well.

Food Tour in Cardiff

While travelling everywhere something that we found really useful to get along with locals it’s to hop on an organized food tour. You can do the same in Cardiff, enjoying the local cuisine, escorted by locals, which will introduce you to traditions, and more indeed insight about the history behind those dishes.

The thriving food scene in Cardiff will let you understand the traditional Welsh food heritage. That will take you from local street food to more delicious fine dishes. The real tradition of Wales it’s made by their unique markets and festivals. However, those are just in a particular time of the year but can be experienced in Cardiff every day through the varied cafes, pubs and restaurants.

Go for a scenic boat ride

Cardiff, it’s beautiful and the good things it’s that you can experience this beauty in many ways. Getting a scenic boat ride from the Mermaid Quay, will give you a different point of view about Cardiff.

The boat ride starts at Bute Park, just next to Cardiff Castle, so will let you go through the River Taff, ending at the Mermaid Quay. The whole journey it’s short, just about 25 minutes. However, this is one of the cheapest experiences to do in Cardiff. The fee’s just about £2 – £4. Despite the public one, this boat ride it’s also possible booking a private boat. Check the availability.

Explore Cardiff’s National Museum

Cardiff has got a National Museum and it’s another iconic building of the Wales Capital. The National Museum of Cardiff it’s right next to Cathays Park. The beautiful Museum offers a huge collection of contemporary art and will get you through the history of this country.

The most interesting thing in this museum it’s the collection of wild ancient animals found in the area. You will be astonished seeing a woolly mammoth and the skeletons of dinosaurs, once roaming freely around this part of the world.

See the Millennium Centre

The huge building that takes the whole landscape of Cardiff Bay it’s the Millennium Centre. It’s relatively a new landmark of the city and offers many activities to locals and tourists. The Millennium Centre it’s an art centre hosting plays, movies, learning classes, galleries and also concerts.

The huge auditorium it’s one of the most incredible in the whole country. The high-standards of this centre can be compared to the west-end performances in London. Check the schedule of the Millenium Centre if you are into musicals, opera, ballet, or also in contemporary dance, hip hop. However the centre it’s open also to the comedy, diversified art exhibition and workshops. The centre also offers behind-the-scenes backstage tours, but we saw that too late to experience it. Don’t make our same mistake and check in advance.

Watch a Rugby Match at the Millenium Stadium

This is the National Sport, and people in Wales are very proud of it, and also competitive. The Millennium Stadium it’s a temple for the people of Cardiff and not only. The beautiful Stadium is located between the seaside and the old town, it’s beautiful and stunning already from outside. If you are a fan of this sport or just curious about this stadium, you should visit the inside.

The stadium’s also hosting football matches, one of the latest more representative was the final of UEFA Champions League. The locals often refer to this as Principality Stadium, and they are very proud of this gem, unique in the whole United Kingdom.
