This ranking was made in 2018 by TripAdvisor. The site relied on the opinions of its community to establish such a list and award its now famous ” Traveller’s Choice Awards “.
Each year, zoos and aquariums around the world welcome more than 700 million visitors (source: WAZA, the world association of zoos and aquariums). A public that seeks to observe animals as closely as possible and learn more about their life in the wild, their conservation, and other information is generally indicated on the animal parks’ explanatory sheets. And to make their visit an unforgettable experience, several criteria come into play, such as the size and layout of the enclosures, the services offered by the zoo, or the species presented. TripAdvisor’s reference site for online reviews has compiled the opinions of its Internet users who have visited zoos around the world. According to the public, this resulted in a ranking among the top 10 zoos to see around the world. Here it is!
