Aqualand S'Arenal is one of the largest water parks in the Balearics, spread over several hectares just inland from the resort. It has been a fixture of the S'Arenal family holiday offer since the mid-1980s and remains the most-visited paid attraction in the area. The park has a full range of slides — the kamikaze near-vertical drops at the top end, lazy rivers and wave pools at the gentler end — along with children's zones for younger kids.
The park is open daily from late May to October, with entry typically around €30 for adults and €25 for children in high season; advance online booking is cheaper. It gets extremely busy in July and August. There is a shuttle bus connection from the main resort strip.
