Around the baobab on the visitorspath there are some signs and stuff. The thing itself is hollow, and has a lot of animalfigures in the wall. Nice for children to discover (although most are in plain sight). You can also climb the baobab which gives a nice view over the savanna (above the right group of giraffes you see a white dot, that's a person standing on the lookoutpoint).
(below, not visible for visitors, will be the night time enclosure for the hyenas.)
