Six Flags Hurricane Harbor

A 25-acre tropical-themed water park up in Valencia, next door to Six Flags Magic Mountain — a great hot-weather escape from central LA. Since 1995 it’s packed in more than 20 slides and attractions for every nerve level: a big wave pool and lazy river for cruising, family raft rides and racing slides, plus steep body and speed slides for thrill-seekers. Add concessions, cabanas and shade, and it’s an easy full-day out for families and groups.
