1. Lagan Valley LeisurePlex


Best for: inflatable fun
This classic leisure centre is slightly smaller than some big-ticket waterparks but has plenty to entertain, including a ‘Mission Inflatable’ assault course filled with rollers, sliders and demolition balls. If you have any energy left afterwards, a ticket for Mission Inflatable gets you 45 minutes in the Leisure Pool, where you’ll find all your waterpark faves, including a Master Blaster slide, a Space Bowl, rapids, waterfalls and a lazy river.
From £2.80. Lagan Valley, Lisburn, Northern Ireland BT28 1LP.
