The Welsh capital city of Cardiff is a popular destination, welcoming nearly 22 million visitors annually from around the world.

Cardiff is a great choice for a family day out or a longer break. It’s a compact city easy to get around and packed with things to do for all ages. Whether you’re travelling with toddlers or teenagers, you’ll find plenty to keep everyone entertained without spending the whole day planning.

From castles and museums to indoor attractions and green spaces, Cardiff offers lots. You can plan a full day out, dip in and out of activities, or keep things simple with free places to explore.

 

1. Go wild in the jungle at Treetop Adventure Golf

Right in the city centre, Treetop Adventure Golf turns a simple game of mini golf into a full-on jungle adventure. As soon as you step inside, you’re surrounded by rainforest sounds and scenery.

The 18-hole course will see you navigate your way through the leafy rainforest canopy, past brightly coloured toucans and singing frogs, whilst thunder and lightning crash all around. If you survive this challenge, try your club at the next 18-hole course. Through the land of the Aztecs, try to appease the ancient spirits and cross the Mystic River.

It works well for mixed-age groups too. Younger children can take their time, while older kids and adults can lean into the challenge. If you’re not playing, it’s still entertaining to watch and there’s food on site if you want to turn it into a longer stop. A solid option when you’re looking for fun things to do in Cardiff with kids, especially on a wet day.

 

2. Learning is fun at Techniquest

Located in Cardiff Bay, Techniquest is the UK’s longest-established science centre and provides detailed interactive adventures for children and adults. Created by leading experts in the science communication fields, their exhibits have appeared all over the world. 

Opening in 1988 with 100 exhibits, the centre has grown impressively and now lives in its own purpose-built building with room for more displays, more visitors and more going on, every day. Inside, you’ll find interactive exhibits covering everything from physics and engineering to space, sound and human biology. Buttons get pressed. Wheels get turned. Questions get asked. It’s designed so children can explore at their own pace, often without realising they’re learning along the way.

Offering a wide range of events such as toddler days and planetarium shows, the whole family can enjoy learning. The on-site cafe is a great spot for a rest, a bite to eat and a cup of coffee.

 

3. Get bouncing at Infinity Trampoline Park

If your group needs to burn off some energy, Infinity Trampoline Park could be just the thing. There are more than 70 interconnected trampolines, making it a space built for movement, jumping, flipping and testing coordination in ways that feel more like play than exercise.

There’s plenty of variety inside. Alongside the main trampoline areas, you’ll find basketball lanes, dodgeball zones and performance beds for anyone keen to try something new. You don’t need to be confident or experienced either. Staff are on hand to keep things safe, and most people pick it up quickly once they’re bouncing.

Infinity also runs dedicated sessions for younger children, as well as inclusive sessions designed to create a calmer environment with adjusted lighting and sound. That flexibility makes it a good shout for families with different needs and abilities.

 

4. Explore Cardiff Castle

Sitting right in the city centre, Cardiff Castle is one of those places you can’t miss. Once you’re inside, there’s far more to explore than you might expect. The grounds tell stories stretching back nearly 2,000 years, from Roman remains to Norman walls and Victorian-era interiors.

Families can wander the open spaces at their own pace, climb the Norman Keep for wide views across the city, or head underground to see the wartime shelters. It’s a good mix of outdoor exploring and sheltered spaces, which helps if you’re visiting with children who like to keep moving.

For families looking for things to do in Cardiff, the Castle works well as part of a wider day out. It’s central, easy to reach and close to other attractions if you want to keep exploring.

5. Discover dinosaurs at National Museum Cardiff

If you’re after things to do in Cardiff for free, the National Museum is a good place to start. Entry is free and the galleries offer plenty to keep children interested, especially the dinosaur exhibits (often a firm favourite).
Inside, you’ll find large skeletons, interactive displays and space to move around without feeling rushed. Alongside natural history, there are art collections and temporary exhibitions. There’s often something new to see, even if you’ve visited before.

The museum’s a good option if you want calmer activity, or a break between busier plans. Because it’s centrally located, it fits neatly into a day spent exploring the city on foot.

 

Whether you’re visiting Cardiff for a long weekend or planning a full family break, there’s no shortage of ways to fill your time. From energetic indoor activities to free cultural spots, it’s a city that lets you shape the day around your family.

The easiest way to get around Cardiff
