The nearest water park to CNP would be The Splash Sur park at Son Ganxo, near Punta Prima.
It’s easy enough to get to by car, passing through Binibeca, otherwise it would involve a bus trip into Mahon and then another bus to Son Ganxo.
Accommodation & Restaurant info for this resort area.
We did the buses to the punta prima water park and it was so easy. Buses are air con so it's not like back home and I think around 2 euro each bus. We always hire a car to go to son bou as we love that beach and the pool with the slides just up from the resort near San Jaime. To be honest I used to drag the kids up to mont torro every year for a pic and go to son bou. Didn't cost a lot for the car oh and dinkums in es castell the kids loved the chicken kebabs and we love the owners. These days we just stay in cnp and get a bus into Mahon for a change. Menorca is beautiful and lots to offer
Cala n'porter my second home - if I could afford it!
