The warm waters of the nuclear complex at Tricastin supply this huge greenhouse inside of which are a tropical garden and a crocodile farm. Various species of crocodilians can be observed in large pools, including albino crocodiles from Louisiana. A little further away is the large greenhouse equipped with footbridges to enable visitors to better admire the lush vegetation, multicoloured birds and, of course, more than 335 fearsome Nile crocodiles.
