Kali River Rapids at Disney’s Animal Kingdom is currently closed for refurbishment.
According to the Walt Disney World website, the ride closed on the 4th January, 2021. Kali River Rapids should reopen on the 2nd April, 2021, according to AllEars.net.
The ride tends to close for refurbishment yearly. Disney chooses to close it during the colder months of the year given that the “ridership” lowers as the temperature does.
