Things to Do in Cardiff
Prices, opening hours, best times to visit and the stuff nobody tells you, everything you need for a first trip to Cardiff, Wales, plus one pigeon's opinions on all of it.
Right, Cardiff. Try the pronunciation, I won't laugh, much, a compact capital with a castle right in the middle of it and a waterfront that's been properly reinvented. This is the proper, no-nonsense guide to things to do in Cardiff: what things actually cost, when to go, what to skip, and which bits are worth the walk. Six main stops below, plus a quiz elsewhere on this site to see if you were paying attention.
Cardiff Castle
A castle sits right in the middle of Cardiff city centre, with parts dating back to Roman times, a properly layered site, Roman fort foundations, a Norman keep, and an extravagant Victorian Gothic Revival interior added by the wealthy Bute family in the 19th century, a very confusing floor plan, from a nesting perspective, but properly fascinating to walk through.
The Victorian interiors, ornate murals, gilded ceilings, and eccentric themed rooms, are worth the extra ticket beyond just the grounds, a proper, slightly over-the-top contrast to the older Roman and medieval layers beneath.
Hours Daily, roughly 9am–5pm, shorter in winter
Address Castle Street, Cardiff CF10 3RB
Cardiff Bay
A waterfront area, once Cardiff's docklands, is now home to the Senedd (Welsh Parliament) and the Wales Millennium Centre, used to be the busiest coal port in the world, now it's mostly people photographing the Senedd roof, a properly striking piece of urban transformation over the past few decades. The Wales Millennium Centre, with its distinctive bronze-clad exterior and Welsh-language inscription across the front, hosts opera, theatre, and major touring shows.
The Senedd itself offers free public access to its viewing gallery when in session, worth a look for the building's design alone, properly transparent both literally and symbolically.
Address Cardiff Bay, Cardiff
Principality Stadium
A national stadium, right in the city centre with a retractable roof, hosts Wales's biggest rugby and football matches, the roof closes faster than you'd think, a fact worth knowing before you assume you have time to relocate if weather turns mid-event. Stadium tours run on non-match days, covering the changing rooms, pitch side, and the technology behind that famously quick roof.
Match day, if your visit lines up with a Wales rugby international especially, offers a properly unmatched local atmosphere, the whole city centre takes on a proper match-day energy well before kickoff.
Hours Tours run on a set schedule on non-match days
Address Westgate Street, Cardiff
National Museum Cardiff
An excellent, free museum covering natural history, archaeology, and a notably strong art collection, including major Impressionist works, a good indoor option and one of the better free museums anywhere in the UK. It sits in Cathays Park, part of Cardiff's grand civic centre, worth combining with a walk through the surrounding formal buildings and gardens.
It's a good, relaxed half-day, particularly welcome if the weather turns during your visit given Wales's fairly reliable rain.
Hours Tue–Sun, roughly 10am–5pm, closed Mondays
Address Cathays Park, Cardiff
Cardiff Central Market
A historic Victorian covered market, still operating much as it has for over a century, butchers, fishmongers, Welsh cakes, and a proper local energy considerably more authentic than a curated tourist experience. It's a good stop for a quick, cheap lunch or picking up genuinely local produce.
Worth the visit for the building itself as much as the stalls, cast iron and glass roofing, a well-preserved piece of Victorian commercial architecture.
Hours Mon–Sat, roughly 8am–5.30pm
Address St Mary Street, Cardiff
Cardiff's Nightlife & St Mary Street
St Mary Street and the surrounding streets form the heart of Cardiff's nightlife, particularly lively on weekends and match days, an energetic, unpretentious scene that Cardiff residents take seriously. It's a good area for dinner too, a wide range of options beyond just the bars.
Worth pairing an evening here with whatever's happening at the Principality Stadium or Wales Millennium Centre if timing allows, the whole city centre properly comes alive around major events.
Best time Evening, especially weekends and match days
Address St Mary Street, central Cardiff
Best time to visit Cardiff
May through September gives the most comfortable weather for the amount of walking this list involves, mild without Wales's more persistent autumn and winter rain.
Cardiff's museums and Cardiff Bay work well year-round, and match days at the Principality Stadium (rugby internationals especially, typically February through March for the Six Nations) are worth planning around if you want the city at its liveliest.
Getting around Cardiff
Central Cardiff, including the castle, the market, and St Mary Street, is easily walkable. Cardiff Bay is a longer walk or a short bus ride from the city centre, both work well depending on your pace and the weather.
