Monarto has many massive enclosures, and the lion area is no exception. However, their website doesn't have an specifics in terms of size of the area, and in truth it should really be updated with more information on how many animals they have and the general layout of the collection. Being able to ride through an exhibit with at least 16 giraffe is a true highlight, and overall it is great to see this open-range zoo continue to expand with the upcoming chimpanzee exhibit.
The Adelaide/Monarto website does have a lot of information on the ten-year giant panda loan that starts in 2009. There is a FAQ section that contains tons of details about pandas, and the plans that are going to be implemented to house them.
