When on your way here, keep an eye out for the Big Rock. This is a 65m-tall artificial mini-mountain, which is an iconic symbol of the Paris Zoological Park. Catching a glimpse of it means you're nearing an encounter with wild animals - including giraffes, rhinos, ring-tailed lemurs, seals and young lions. A day here puts you right into the heart of an animal-centric adventure. Don't forget your camera and pith helmet.
