by Bryony Firth-Bernard |

If you’re looking for a fun family day out you should definitely consider visiting an indoor water park.

Indoor water parks are a great way to get active with your little one; you can visit them no matter the weather as they’re inside and with many cool features, including water slides and wave machines, tots (and adults) are guaranteed to be entertained for the whole day.

So, if you’re keen to get your cossie on, or trunks, keep on reading, as we’ve trawled the web to narrow down the best indoor water parks in the UK for a splashing day out.

Sandcastle Waterpark, Blackpool

This is the UK’s largest indoor water park located on Blackpool’s famous promenade, with over 18 waterslides and attractions. Kids can enjoy jumping through the waves from the wave machine, shooting down the Master Blaster, the world’s longest indoor roller coaster water slide which is 250 metres long, or having a splash in one of the fun pools. There’s also plenty of play structures for little ones too, a restaurant and even a spa, so you can really make a whole day of it.

Verified customer review: “Great place to visit, especially when the weather's not so good. Some really fun slides, and seems clean and well run. The food in the cafe was pretty good too!”

Waterworld, Staffordshire

This tropical indoor water park has over 30 rides and attractions for non-stop fun, including Thunderbolt, the famous first trapdoor drop water slide where you’re enclosed in a tube before being dropped into a 25mph water flume. It’s also got your classic wave pool, rapids, flumes and a lazy river ride too. If the weather’s good you can even venture outside to the outdoor pool, to catch what’s left of that summer sun.

You must book your tickets beforehand. Ticket prices and opening hours can be found here.

Verified customer review: “Great indoor pool fun. Kids love it as well as grown-ups going down the slides"

Splashdown, Dorset

Splashdown is great for families with youngsters. As well as 13 exciting indoor and outdoor waterslides, there are three splash zones for children under five, so everyone can join in the fun. Personally, we love the ride ‘Infinity’ where you slide around a big bowl with music and funky lasers, before being plunged into the pool below. There’s also a cafe and sun terrace too, just in case you want to top up your tan if the weather’s on your side.

Verified customer review: “ Great fun for all ages. We had a five-year-old and we ourselves are retirees, I am over 70 and even went on the Infinity flume, haha. Superb session!”

The LC Swansea, Glamorgan & Cardiff

Families can enjoy the famous wave-pool, slipping down one of the slides or floating round the lazy river. It's a great indoor water park for toddlers too, as little ones can enjoy the day in volcano bay, which still has mini slides and interactive areas to keep them entertained.

Verified customer review: "Used the pool twice. The kids love it here. Always plenty to do. With a 1 year old and a 7 year old, it's not always easy to entertain them both at the same time, but this pool does the lot. There's different areas for differing swimming abilities and the wave machine always gets a good laugh! Will be back soon!"

Alton Towers Water Park, Staffordshire

You can pretend you’re abroad at this cool Caribbean-themed indoor water park, located at the Splashing Landings Hotel at Alton Towers. Inside the tropical indoor area kids can zip down the super speedy ‘Master Blaster’ water coaster, splash in the waterfall in Lagoona Bay or go wild in the Wacky Waterworks, which has water wheels and cannons. The Little Leak area has shallow water and plenty of fun and games for smaller children too.

Entry to the theme park isn’t included in the ticket price, however you can pay a little extra to add this on. Ticket prices and opening hours can be found here.

Verified customer review: “What a fantastic water park! We never thought we would be in there for a couple of hours but ended up staying all day! Great slides, nice food and a very safe environment.”

The Wave, Coventry

This award-winning indoor water park is home to the largest wave pool in the UK, holding 20 million litres of water! The Reef is great for younger splash seekers, with mini slides and jets, while bigger kids have the choice of six slides, a wave pool and The Lazy River for when they need to wind down. Afterwards, you can pop along to Cofa’s Cafe, which offers a range of hot and cold snacks and drinks. Whether you’re a thrill or chill seeker, The Wave has something for everyone.

Verified customer review: “What an amazing place. We had great fun as a family. We had a 12 year old boy who thought this place was the best. Another great point is the multi story car park is next door and it's a 2 minute walk. Also after the fun is over there is a great little restaurant and it's reasonably cheap, they do a great chip and curry sauce.I would recommend this place to anyone that loves water. Well done The Wave.”

Calypso Cover Waterpark, Barnsley

Let your little one hunt for buried treasure at this pirate themed indoor water park, which features a massive skull and huge pirate ship. Kids can walk the plank, zip down one of the many slides or flumes, or relax in the Still Waters Pool, the Hideout or Sunken Galleon.

You must book your tickets beforehand. Ticket prices and opening hours can be found here.

Verified customer review: “This is a really fun place to go with children aged 2+. There is a toddler pool for the youngest through to water slides, a wave machine, pirate ship with slides and a bigger pool for the oldest. On the day I visited there was an official photographer who took photos, on request, and you can purchase them on the way out (£12 per photo, £24 for 3 photos etc). Lots of fun and activities for everyone regardless of swimming ability.”

Lagan Valley Leisure Pool, Lisburn

This is a lot smaller compared to your traditional waterparks, but we had to include it as it’s great for small children. There’s waterslides to splash down, a lazy river and lots of little waterfalls. If you have older children with you, why not pay a little extra for them to have a go on ‘Mission Inflatable’, an assault course featuring demolition balls, slides and rollers? There’ll be smiles all round all day.

Verified customer review: “Great day out for children and adults. Plenty of parking spaces at the complex. Very clean and well kept. Lots of fun on all the waterslides and the lazy river. Highly recommend.”

Coral Reef Water Park, Bracknell

Another pirate-themed water park is Coral Reef. It's one of the largest water worlds in the UK, so you and your tot can expect to have an amazing aqua adventure. There's some brilliant features such as the big pirate ship that squirts water and lots of water slides. There's also the little coral children's area and, don't worry adults, there's also a spa area too for a little relaxation.
