Things to do in Cardiff at a glance

Castles and heritage: things to do in Cardiff for history fans

1. Cardiff Castle

Cardiff Castle is the city’s headline attraction. Additionally, a Norman keep stands beside lavish Victorian interiors, and the grounds sit in the middle of the city. Entry costs about £16 to £17 for an adult, and you can book online or buy on the day if space remains.

The castle opens daily, at 9am on weekends and 10am on weekdays. Moreover, it closes at 6pm from March to October and 5pm from November to February, and last entry falls an hour earlier. However, event days can change these times, so check the website before you go. Allow two to three hours if you want to climb the keep and join a house tour.

2. Castell Coch

Castell Coch looks like a storybook castle on a wooded hill north of the city. Furthermore, William Burges rebuilt it for the Marquess of Bute in the Victorian period, and Cadw now cares for it. It sits at Tongwynlais (CF15 7JS), about a 15-minute drive from the centre, and paid entry applies. Moreover, the woodland trails around it are free, so you can combine the castle with a walk.

3. Llandaff Cathedral

Llandaff Cathedral stands in the quiet village of Llandaff, a short bus ride or drive from the centre. In addition, visitors come for the architecture and the modern sculpture inside. Because it is a working church, check service times before you visit. Meanwhile, the village itself offers cafes and a calmer pace than the city.

4. Principality Stadium

The national stadium sits in the middle of the city, beside the River Taff. Tours run on non-event days, and the venue hosts rugby, football and concerts. Since it has no spectator car park, read our Cardiff parking guide and the park and ride guide before event days.

Museums and culture

5. National Museum Cardiff

National Museum Cardiff, in Cathays Park (CF10 3NP), is free to enter. Additionally, it holds one of the finest impressionist art collections outside Paris, along with natural history and geology displays. Some exhibitions carry a charge, so check what is on. Allow at least two hours, because the galleries are large.

6. St Fagans National Museum of History

St Fagans covers about 100 acres in west Cardiff (CF5 6XB). Moreover, it features more than 50 historic buildings, including farmhouses, a chapel, shops and a pub. Entry is free, but parking carries a charge. Therefore, plan a full day, wear comfortable shoes and bring a waterproof, because the site is large and mostly outdoors.

7. Museum of Cardiff

The Museum of Cardiff tells the story of the city through displays and objects. Furthermore, it is free to enter, so it makes a good short stop in the centre. In addition, it helps first-time visitors understand how the docks shaped the city.

8. Wales Millennium Centre

The Wales Millennium Centre is the national arts centre for Wales. In addition, it hosts touring musicals, opera and dance. It also offers free performances on the Glanfa stage, so look at the programme even if you do not buy a ticket. Consequently, an evening visit can cost nothing.

Cardiff Bay: things to do in Cardiff by the water

Cardiff Bay is a compact waterfront district. Similarly, a flat path links most of the sights, and cafes and restaurants line the quay. As a result, the Bay works well as a half-day on its own.

9. Mermaid Quay and the waterfront

Mermaid Quay is the main hub for food, drink and views. Additionally, take a stroll along the water, then choose a cafe. Because many sights stand close together, you can see several without crossing a road.

10. The Senedd

The Senedd is the Welsh Parliament building, designed by the architect Richard Rogers. Moreover, visitors can enter the public areas and take tours. It is free to enter, and the glass-fronted design makes it easy to photograph.

11. Pierhead Building

The red-brick Pierhead Building was once the base of the Bute Dock Company. Furthermore, today it hosts an exhibition about the history of devolution and the area. It sits beside the Senedd, so you can visit both in a single stop.

12. Norwegian Church Arts Centre

The Norwegian Church was built to serve Norwegian sailors. In addition, it is also the church where the author Roald Dahl was christened. Today it houses an arts centre and a cafe, and it makes a pleasant place to pause by the water.

13. Cardiff Bay Barrage walk

The barrage links Cardiff Bay to Penarth, and the flat path suits walkers and cyclists. Similarly, it forms part of the Wales Coast Path and gives wide views over the water. If you do not want to walk both ways, you can use the Waterbus for one leg.

14. Techniquest

Techniquest is a science and discovery centre in Cardiff Bay (CF10 5BW). Additionally, adult tickets have been listed at around £11 to £12 online. It suits families with children of all ages, and it works well on wet days.

15. Cardiff Bay Wetlands Reserve

The wetlands reserve lies a short walk from Mermaid Quay. Moreover, a boardwalk leads to a viewing platform, and entry is free. Birdwatchers can look for rare species, while casual walkers enjoy the quiet path.

16. Cardiff International White Water

The white water centre offers rafting and kayaking in Cardiff Bay. Furthermore, it suits groups who want an active day. Book ahead, and check age and fitness rules before you go.

The Waterbus runs as a public transport service and for sightseeing cruises. It offers a fun alternative to walking along the barrage, and children usually enjoy it.

Parks and green spaces

19. Roath Park

Roath Park centres on a large lake, with gardens and the Scott Memorial Lighthouse on the water. Similarly, a new heritage trail opened in 2026, so there is more to read as you walk. It suits families and gentle walkers.

20. The Taff Trail

The Taff Trail starts in Cardiff Bay and runs north along the river. Additionally, you can walk or cycle short sections, so it suits a flexible afternoon. Furthermore, it links several parks and the city centre without busy roads.

21. Dyffryn Gardens

Dyffryn House and Gardens lies just outside Cardiff in the Vale of Glamorgan. Moreover, this National Trust property has extensive gardens and a children’s play area. It suits a relaxed half-day, though you will need a car or a bus journey to reach it.

Shopping and local life

22. Cardiff Market

Cardiff Market is a Victorian covered market in the centre. Furthermore, you can find food, books, records and local goods under one roof. It is a good rainy-day stop, and the stalls make it easy to grab a snack.

23. The Victorian arcades

Cardiff’s arcades run between the main streets, and Royal Arcade dates from 1858. In addition, they hold independent shops, cafes and tea rooms. If you want a meal, see our guide to brunch in Cardiff. Additionally, the arcades stay dry in bad weather.

How to choose between the things to do in Cardiff

Twenty-five options can feel like a lot. Use this table to narrow them down.

Free things to do in Cardiff

Many of the best things to do in Cardiff cost nothing. Use this list to plan a low-cost day.

• Walk through Bute Park and along the Taff.

Together, these choices fill two full days. However, remember that some temporary exhibitions and events charge entry, even inside free venues. Therefore, check the programme before you go.

Rainy-day things to do in Cardiff

Cardiff gets plenty of rain, so keep an indoor plan. The national museum, the Museum of Cardiff, Techniquest, Cardiff Market and the arcades all work well. In addition, the Wales Millennium Centre has free space to browse, and Cardiff Castle’s interiors keep you dry during a house tour. Consequently, you rarely lose a day to the weather.

Things to do in Cardiff with kids

Families can mix indoor and outdoor choices. Techniquest and St Fagans suit most ages, while Bute Park and Roath Park give children space to run. Meanwhile, the Waterbus adds a short adventure, and Cardiff Castle’s keep rewards anyone who enjoys climbing.

In winter, Winter Wonderland adds rides and ice skating. Book skating slots early, because they sell out on weekends.

Things to do in Cardiff in the evening

Evenings in Cardiff centre on food, music and theatre. The Wales Millennium Centre runs shows most nights, and the city’s bars and restaurants stay busy through the week. Moreover, Cardiff Bay looks attractive after dark, when the waterfront lights come on. In winter, the Bute Park light trail and Winter Wonderland give you extra reasons to go out after dark. If you plan a big night out, read our guide to bottomless brunch in Cardiff for a daytime alternative.

Costs to expect

Budgeting is easy in Cardiff because many sights are free. A day that combines Bute Park, a museum and the Bay can cost nothing beyond food and transport. If you add Cardiff Castle and Techniquest, expect to spend around £27 to £29 per adult on entry alone. Similarly, a family of four should budget more for tickets, so look for family deals on official sites. Therefore, set a daily limit before you choose paid attractions.

Sample itineraries

A realistic one-day plan

1. 9:30am: Arrive at Cardiff Castle and climb the keep first, before the crowds.
2. 12:00pm: Eat in one of the arcades.
3. 1:30pm: Walk through Bute Park beside the river.
4. 3:00pm: Visit National Museum Cardiff until closing time.
5. 5:30pm: Take the train to Cardiff Bay for dinner.

This plan keeps walking distances short. Furthermore, it places the paid attraction in the morning, when energy is high.

How to get around

The city centre is walkable, and trains run to Cardiff Bay and the suburbs. Buses link the rest of the city. If you drive, compare car parks first, because costs vary widely. Meanwhile, Cardiff Central station sits in the middle of the city, so rail visitors can start sightseeing within minutes of arrival.

When is the best time to visit Cardiff?

Spring and early summer bring the best weather for parks and the Bay. Autumn colours make Bute Park beautiful. Winter adds the markets, the ice rink and the light trail, but it also brings cold and rain. Therefore, choose the season that matches the things to do in Cardiff you care about most.
