For recreation with children, you can choose almost any "point" in Ibiza, it's not even about children, it's about parents, what's more to their liking, whether a quiet rest is still a kind of dynamics. Almost in all, even the most dynamic zones, there are hotels of a very family type .But there are areas where the rest is quite calm, such as: Port San Miauel, Cala Sant Vicent, Portinatx, all these areas are ideal for families with children, regardless of age, but remotely located from the main places of leisure .As a "golden mean", you can advise the town of Santa Eularia or the bay of Cala Llonga (in the South-East) or for example Cala Tarida (in the West) .As for the "What to see / where to go?" », There are also lots of places, it is the complex historical center of Ivyssa with the fortress of Dalt Vila, promenade along the sea in the Marina Botafoch area or in Santa Eularia, as well as numerous beautiful natural places .There are two water parks on the island, one in Cala de Bou (San Antonio) and one in Playa d'en Bossa .Virtually all the most crowded places of residence there are small amusement parks .Like this :)
