The Pangolin are located in a red lit exhibit in Habitat Africa The Forest behind a curtain located after the Dwarf Crocodile and Hornbill/Duiker exhibit within the indoor portion. When you enter the building walk just past the Dwarf Croc exhibit and take a right. The Pangolin is generally viewable at most times asleep within his log in the upper right corner of the exhibit. There is a Pangolin feeding that, I believe, is at 4:00 pm when he is most active, though I recommend you double check the times. There is only one Pangolin on exhibit with very few spots where he can completely hide. However, he is almost always asleep and in a rather not photogenic area.
