I've taken a few whole-day excursions to zoos now and the same problem arises every time, I get dizzy by the end of the day and have to rest until tomorrow as the dizziness disappears after a good night sleep.
I'm pretty sure now that this happens due to me being exposed to the sun for a longer...
Part of the tree-top walking in the South America Dome in Randers Tropical Zoo, Denmark. From here you get a fantastic birds-eye view of the dome and life in the treetops.
