About Us


Harbour Splash

Dublin’s first aqua park located at the Old Pier in Dún Laoghaire Harbour.

The Aqua Park is an inflatable obstacle course offering the most fun you will have on the water this summer! Perfect for birthdays parties, hen and stag do’s, corporate events and family days out.

Find out more about kids birthday parties, school tours, adult group activities and family days out.

Our course is a great combination of slides, trampolines, climbs, monkey bars and other obstacles that are great for people of all ages and fitness levels.
So come make a big splash!

Children aged 8 upwards can be booked on the park anytime (accompanied by an adult for ages 8 – 9). For younger kids (6-10 year olds) we run special ‘slow fun’ sessions on Saturday and Sunday mornings where they can enjoy the park together with a parent/guardian.

Ticket Prices:
Single Session under 18s: €18
Single Session over 18s: €22
Wetsuits, vests and helmets are provided free of charge. 

Group rates are available for groups of 10 or more people and the reduced price is €16 per person for under 18s and €20 per person for over 18s.

Our Facilities

We have basic changing facilities on site, but you should treat your time with us like a trip to the beach. Pack your towels & swimwear and leave your valuables at home.

Public toilets are located nearby at a €1 charge.

How to get to us:

Harbour Splash is located at the Old Pier in Coal Harbour near the west pier.  We recommend to take public transport for your trip to us – the DART and bus stops are very close by and there is no designated parking for Harbour Splash in the area, there is only very limited pay parking available in the harbour. We don’t want you to miss your slot because you couldn’t get parking.
