Rafiki's Planet Watch isn't really a "land" and not really an attraction either. Our best guess is that Disney is using the name as an umbrella for Conservation Station, the petting zoo, and the environmental exhibits accessible from Harambe via the Wildlife Express Train from Africa. Presumably, Disney hopes that invoking Rafiki (a beloved character from The Lion King) will stimulate guests to make the effort to check out things in this far-flung outpost of the park.

Note that this land is generally open only 10 AM to 5 PM, although it may be open later on busy days during times of year when it stays light later into the evening.
