Grand Baie's only specific sights are a couple of vividly colourful, roadside Tamil temples of limited interest.
Feature: Île Ronde & Île aux Serpents
Île Ronde (Round Island) and Île aux Serpents (Snake Island) are two significant nature reserves about 20km and 24km, respectively, from Mauritius. It is not possible to land on them. Ironically, Île Ronde is not round and has snakes, while Île aux Serpents is round and has no snakes; the theory is that an early cartographer simply got them confused.
Île Ronde covers roughly 170 hectares and scientists believe it has more endangered species per square kilometre than anywhere else in the world. Many of the plants, such as the hurricane palm (of which one lonely tree remains) and the bottle palm, are unique to the island. The endemic fauna includes the keel-scaled boa and the burrowing boa (possibly extinct), three types of skink and three types of gecko. Among the seabirds that breed on the island are the wedge-tailed shearwater, the red-tailed tropicbird and the gadfly (or Round Island) petrel. Naturalist Gerald Durrell gives a very graphic description of the island in his book Golden Bats and Pink Pigeons.
The smaller Île aux Serpents (42 hectares) is a renowned bird sanctuary. The birds residing on the island include the sooty tern, the lesser noddy, the common noddy and the masked (blue-footed) booby. Nactus geckos and Bojer's skinks are also found here.
