The nearest aqua park is on the Fuengirola ring-road next to the turn off for Coin/Mijas Golf. The other is located near Torremolinos. Families travel from as far away as Gibraltar to spend a day at the Mijas aqua park. The aqua parks open from about Easter onwards for the summer season. Look out for special entrance offers in the local English newspapers (The Entertainer & Sur).
