Silhouette
is the most eastern from the granitic islands.
Despite only 20
km separates Silhouette from Mahé it was never exploited like
the other islands, and this thanks to its mountainous character,
and its protection by the coral reef.

fourth in population. It is 6 km long and 4km wide, its highest
