ANIMAL KINGDOM KALI RIVER RAPIDS WATER RIDE in Disney World Fun Kids Vacation Review by Haileys Magical Playhouse. Hailey goes on a fun water ride at Animal Kingdom called the Kali River Rapids water ride. Hailey is so cute and brave as she plummets down the whitewater river on this awesome water ride. Its a bit different than a rollercoaster and you will get wet or even soaked as you cruise the river rotating around on a 12 person raft. \rbr\rbrWe really enjoyed the water ride and suggest getting a fastpass for it. It requires a child to be 38 inches or taller (97cm), mildly spins, and has only one major drop during the water ride.
