Harbour Splash Inflatable Aqua Park

If you are looking for a fun time outdoors and on the water with plenty of adrenaline kicks, book a session at Harbour Splash, Dublin’s first inflatable aqua park at Dún Laoghaire Harbour.

The park’s trampolines, slides, jumps, monkey bars and climbing walls are the ideal playground for a kids birthday party or a family day out. Don’t miss out on the blast bag - the kids love it! It works even better when parents jump on the bean bag to blast their kids in the air! If you haven’t seen it, have a look at it here:

Harbour Splash is ideally located at the west pier in Dún Laoghaire Harbour, only a 10 minute walk for the Salthill/Monkstown or Dún Laoghaire DART stations with a public car park right outside the door.

Celebrate your birthday with a splash:

The easiest way to make a group booking is to call Harbour Splash at 01-5240602 or email your enquiry to

When booking in, make sure to arrive 30-45 minutes before the session starts for check in and getting changed. Sessions are one hour long including the safety briefing by the lifeguards and afterwards you need to factor in another 15 minutes to get changed.

If you are booking for young children (under 10 years), adults need to go on the water with the kids, from age 10-15 an adult has to stay on site for the duration of the session.

Perfect to challenge your friends or colleagues to a race NinjaWarrior style!
