Rain doesn’t have to mean a day stuck staring at four walls. Northern Ireland has a brilliant spread of indoor attractions built for exactly this kind of weather — splash parks, museums, science centres, soft play and even a genuine cave system to explore. Whether you’re in Belfast for the afternoon or looking for something further afield, here’s our round-up of the best rainy day activities for kids in Northern Ireland.
Indoor Splash!
Based at Lisburn Leisure Park just outside the city centre, the Lagan Valley LeisurePlex boasts one of the largest leisure pools of its kind in Northern Ireland, with fast, long and genuinely soaking water rides.
At Bangor Aurora Aquatic & Leisure Complex, you’ll find Northern Ireland’s only 50m pool alongside the Aurora Splash Leisure Waters — two large flumes, slides, a wave machine, water features, a baby beach and a pirate ship. There’s also an Adventureworld soft play zone with swings, slides and plenty of climbing, open daily.
History & Heritage
Titanic Belfast
At Titanic Belfast, explore the Titanic story in a fresh, immersive way. Journey through the shipyard, descend to the depths of the ocean and uncover the full story of the ship, in the city where it was built. With several levels of interactive exhibits tracing the Titanic’s journey from industrial Belfast to the final tragedy, there’s plenty here for all ages.
Ulster Museum
Ulster Museum, in Belfast’s Botanic Gardens, is free to visit. Pick up a kids’ explorer map and stickers at the welcome area to help plan your route around the museum. Discover how big dinosaurs really were, what a mummy looks like, and treasure lost at sea, alongside three interactive discovery zones — Discover Art, Discover Nature and Discover History — that are packed with things to do.
Nomadic, Belfast
The SS Nomadic — tender to the Titanic and the last remaining White Star Line ship in the world — has been restored to her original glory and sits back home in Belfast’s historic Hamilton Dock. Go on board and step into over 100 years of maritime and social history.
Crumlin Road Gaol
Crumlin Road Gaol in Belfast dates back to 1845 and closed its doors as a working prison in 1996. Today it’s a visitor attraction with guided tours covering the site’s history. Visit the underground tunnel that once connected the gaol to the Crumlin Road Courthouse, sit in the Governor’s chair, view the wings from the circle, and see the condemned man’s cell and execution cell.
Science Fun
W5 at Odyssey in Belfast is Ireland’s award-winning science and discovery centre, with over 250 interactive exhibits and a changing programme of events, shows and exhibitions — a great value day out for the whole family.
Movies & More
Brunswick Moviebowl, at Pennyburn Industrial Estate, has something for everyone: a multi-screen cinema, cosmic ten-pin bowling, and Banana’s Adventure Park indoor play centre. Plenty to keep the kids — and you — happy on a wet day.
Or skip the trip altogether and bring the cinema home. Get the kids involved in setting up seating, making tickets and choosing snacks, then settle in together.

Get Creative
Let the kids learn through play at Jumping Clay, Belfast. JumpingClay is a jasmine-scented, mess-free clay that bounces when rolled into a ball and thrown or dropped. There’s no baking required, and finished creations can be kept forever. Join a children’s or family workshop, sign up for a Saturday club, or book a party.
Explore Caves, Stars & Sea!
The Marble Arch Caves Global Geopark sits in the rugged uplands and gentle lowlands of counties Fermanagh and Cavan. Taking in the world-famous Marble Arch Caves, the Geopark showcases some of the finest natural landscapes in Ireland and a window into 650 million years of history.
Armagh Planetarium is a renowned astronomical education centre bringing astronomy to a wider audience. Explore the exhibits and catch one of the family shows in the dome.
Exploris Aquarium, Portaferry, sits on the shores of Strangford Lough. Learn about the marine life of Strangford Lough and the Irish coastline, see the open sea tank and Discovery pools, and don’t miss the seal sanctuary, home to rescued seal pups being rehabilitated for their return to the wild.
Get Outside
Sometimes, you’ve just got to get out and get wet. Pop on the raingear and wellies and head out for a walk in the rain — most kids love splashing in puddles, and it’s a great way to burn off pent-up energy from being cooped up inside.
Warm up afterwards with a hot bath or shower, dry clothes and a hot chocolate. Then pull out a board game or snuggle up on the couch with a movie — a perfect end to a wet day.
