I love the area around the ibex mountain, with takins, marmots, barbary sheep (i think) and ibex. The enclosures are mostly really good and adequate and this just looks so beautiful.
@Paul Kalisch I am also very found of this area. Prefer to approach the zoo through the Lion's door, because this is the first thing you see, when enter. Interestingly, I found the room on the top of the Alpine area open. The walls are covered with Mountain Caprine paintings and from there you can observe the Himalayan Tahr closely. The access was restricted, cos of Corona, though.
