Aquarama is a sizeable water park at the south end of Benicàssim, big enough to keep children entertained for a full day. The standard mix — a couple of long twisting slides, a wave pool, a lazy river, kiddie pools — is laid out across a shaded site planted with palms and lawns. Decent restaurant and a small shop on site; entry is around €30 for adults at the gate.
It is open daily from June to mid-September and is a useful family option in the worst heat of the day. Two-day combination tickets are sold for the park; the more spectacular Marina d'Or aquatic complex further north is the alternative.
