The zoo installed a new gate system for their Zoofari ride back in 2021. Previously, you would board a shuttle bus in Junction Plaza that would take you to the end of the Baboon/Antelope trail, where you would board the Zoofari bus in an area enclosed by thick poles.
Now, you board the Zoofari bus directly at Junction plaza, and the ride takes you back to Junction Plaza where you disembark there, instead of at the end of the Antelope trial previously.
Also, there is a third gate just behind us in this photo, so the Zoofari bus traverses 3 gates to enter/exit the enclosure.
