Why Cardiff?
Cardiff is the capital of Wales, and it punches way above its weight. It’s small but packed with personality. In just a few days, you can explore ancient Roman ruins, ride a water taxi across Cardiff Bay, catch a live gig in a back-alley club, and eat enough Welsh cakes to consider moving here.
If you’re wondering about the top things to do in Cardiff, you’re in for a treat — this city delivers way more than you’d expect.
It’s also one of the most walkable cities in the UK — you don’t need a car, just a good pair of shoes and an open mind.
🗓️ Day 1: Castles, Coffee & the Bay
🏰 Cardiff Castle
You can’t miss it — Cardiff Castle is right in the city centre. It dates back to Roman times, was later built into a medieval stronghold, and eventually turned into a Victorian Gothic fantasy by the Marquess of Bute.
If you’re making a list of essential things to do in Cardiff, this one’s top tier.
Don’t just walk the walls — get inside. The Clock Tower rooms are jaw-dropping (think gold leaf, astrology murals, and a bit of madness). And if you’re into history, check out the wartime tunnels used as air raid shelters during WWII.
Did you know? The Animal Wall outside the castle features stone animals sculpted in the 1890s — and locals still argue over which one’s the weirdest.

☕️ Coffee & Culture in the Arcades
Cardiff’s arcades are narrow Victorian shopping streets filled with indie cafés, vintage stores, music shops, and art spaces. They’re quirky, beautiful, and local-approved.

- Where to shop: Spillers Records (world’s oldest record store), Sobeys for vintage, and Wally’s Deli for Welsh treats
🌊 Head to Cardiff Bay
Once the busiest coal-exporting port in the world, Cardiff Bay is now a laid-back mix of history, architecture, and open space.
Cardiff Bay is one of the top things to do in Cardiff for locals and visitors alike. It’s where the city unwinds — with history, sea air, and open skies.

It’s one of the more unexpected things to do in Cardiff — and absolutely worth half a day.
It’s free, family-friendly, and surprisingly peaceful — even in peak season.

🗓️ Day 3: Parks, Pints & Penarth
🌳 Bute Park & The Taff Trail
Cardiff is full of green space, but Bute Park is the star. It’s bigger than Hyde Park and stretches from the castle all the way north along the River Taff.
Rent a bike, jog along the trail, or just grab coffee at the Secret Garden Café and do absolutely nothing.
