As you know, this past summer I was in Scandinavia and at Kristiansand Zoo in Norway there were visitor tunnels that looked into the lion and tiger exhibits. Parc Safari has the same thing here and I wonder how many zoos worldwide have tunnels through exhibits for both lions and tigers. Parc Safari's enclosures look nice but very basic, while the big cat exhibits at Kristiansand are stunning and world-class.
@snowleopard These would definitely look better if they weren't chain link, but they were still really neat! My dad especially thought they were amazing. The place I went the next day had mini versions that just went in a bit, weren't full tunnels.
