What to Do in Cardiff: 10 Fun Things

You’ll find Cardiff offers more than most visitors expect from Wales’ capital. Beyond the obvious tourist spots, there are hidden tunnels beneath the castle, free sculpture trails through Victorian parks, and authentic Welsh experiences that won’t drain your wallet. Whether you’re here for a weekend or just passing through, these ten activities mix must-see attractions with local favorites that’ll give you a genuine taste of what makes this city tick.

Explore Cardiff Castle’s Secret Wartime Tunnels and Fairy-Tale Rooms

While most visitors admire Cardiff Castle‘s Victorian Gothic revival architecture, you’ll discover a hidden chapter of history beneath your feet in the secret wartime tunnels. These intramural galleries within the castle’s Roman and medieval walls sheltered up to 2,000 Cardiff residents during WWII air raids between 1940-1944.

You’ll explore eight sections separated by blast walls, complete with original bunks, canteen areas, and first aid posts where locals sought refuge from over 2,100 bombs that fell on Cardiff. The tunnels showcase ingenious wartime adaptation—wooden ramps provided street-level access while arrow loops served defensive purposes for centuries. The shelters featured essential amenities including a small kitchen that supplied hot drinks and simple food to help sustain refugees during the long, tense nights of air raids.

Book guided tours to access these hidden shelters alongside the castle’s opulent fairy-tale rooms, offering remarkable value for experiencing both medieval grandeur and wartime resilience in one visit.

Wander Through St Fagans Open-Air Museum for Authentic Welsh History

Just seven miles west of Cardiff’s city center, St Fagans National Museum of History offers you an authentic journey through 2,000 years of Welsh life without spending a penny. You’ll explore over 40 relocated historic buildings across 100 acres, from Iron Age farmsteads to 20th-century prefabs.

Watch skilled craftspeople demonstrate traditional blacksmithing, weaving, and pottery-making techniques that locals have used for generations.

The working mills still produce flour and wool for sale, while native Welsh livestock roam authentic farmyards. Plan 2-4 hours to fully appreciate the village-like layout.

Volunteers stationed throughout share fascinating stories that bring each building to life. The recent £30 million renovation added excellent galleries and improved facilities, making this Wales’s top heritage attraction even more engaging for budget-conscious travelers. This Museum of the Year 2019 winner continues to set the standard for open-air museums across the UK.

Take a Leisurely Walk Through Bute Park’s Sculpture Trail

Right in Cardiff’s heart, Bute Park’s free Sculpture Trail transforms your casual stroll into an artistic treasure hunt across 130 acres of green space. You’ll discover over 20 unique sculptures crafted from the park’s own felled trees, making this a genuinely sustainable art experience that won’t cost you a penny.

The trail’s perfect for families since many sculptures double as interactive play elements. Kids can climb, explore, and let their imaginations run wild while you appreciate the artistic craftsmanship.

You’ll find everything from carved animal figures to abstract forms tucked along woodland paths. The park also features a nationally significant arboretum collection with rare trees from around the world.

Access the park easily from Cardiff city centre or Central Station through multiple entrances. Grab a trail map from bute-park.com, then combine your sculpture hunting with the Champion Tree Trail or Story Trail for a fuller park experience.

Sample Welsh Delicacies at Cardiff Central Market

Since the 1700s, Cardiff Central Market has served as the city’s culinary heart, and you’ll find it’s still the best place to sample authentic Welsh delicacies without breaking the bank. Start with traditional Welsh cakes from Bakestones – these sweet pancake-scone hybrids cost just pennies and offer the perfect introduction to Welsh cuisine.

For adventurous eaters, head upstairs to The Bullterrier café for laverbread, a unique seaweed paste that’s quintessentially Welsh. Don’t miss the cockles with Sarsons vinegar, artisan Caerphilly cheese, and hearty cawl broth. This traditional lamb stew combines vegetables like leek, potato, and carrot, making it ideal for cold days.

The Victorian market also houses international vendors like The Bearded Taco and Bao Selecta, plus vegan options at Naked Vegan. This blend of traditional Welsh fare and global flavors makes it Cardiff’s most authentic yet diverse food destination.

Catch a Rugby Match or Concert at Principality Stadium

Whether you’re cheering for Wales during a Six Nations match or swaying to live music under the retractable roof, Principality Stadium delivers Cardiff’s most electrifying experiences. This 74,000-capacity venue transforms from rugby battleground to concert hall thanks to its innovative roof system—the UK’s first retractable design.

Rugby tickets start around £25 for upper-tier seats, while premium matches can reach £100+. Book early for Six Nations fixtures, as they sell out quickly.

Concert pricing varies markedly by artist, but upper-tier seats offer decent views at lower costs. Most performances wrap up between 22:30 and 23:00 due to local noise regulations.

The stadium’s “joy machines” dispense twelve pints in twenty seconds, though expect premium pricing. Arrive early to soak up the pre-match atmosphere in nearby pubs for better-value drinks and authentic Cardiff rugby culture.

Built between 1882-1889, this arcade features beautiful balconies offering split-level shopping among vintage clothing stores and artisan coffee shops.

For serious record hunting, head to nearby Morgan Arcade where you’ll find Spillers Records—the world’s oldest record shop established in 1894. This legendary shop has maintained its position as a cultural institution throughout Cardiff’s retail transformations and economic challenges.

The arcade network’s small units encourage niche businesses, making them perfect for discovering rare vinyl and vintage finds without breaking your budget.

Cycle the Taff Trail From Pontcanna to Cardiff Bay

Swap castle turrets for riverside views on the Taff Trail, where you’ll find one of Cardiff’s best free activities just a short ride from the city center.

This 3-4 mile stretch follows the River Taff through Pontcanna Fields, Sophia Gardens, and Bute Park before reaching Cardiff Bay’s iconic Roald Dahl Plass.
