Seychelles, one of the world’s smallest countries, is composed of two main island groups: the Mahé group of more than 40 central, mountainous granitic islands and a second group of more than 70 outer, flat, coralline islands. The islands of the Mahé group are rocky and typically have a narrow coastal strip and a central range of hills. The overall aspect of those islands, with their lush tropical vegetation, is that of high hanging gardens overlooking silver-white beaches and clear lagoons. The highest point in Seychelles, Morne Seychellois (2,969 feet [905 metres]), situated on Mahé, is located within this mountainous island group. The coralline islands, rising only a few feet above sea level, are flat with elevated coral reefs at different stages of formation. These islands are largely waterless, and very few have a resident population.
The climate is tropical oceanic, with little temperature variation during the year. Daily temperatures rise to the mid-80s F (low 30s C) in the afternoon and fall to the low 70s F (low 20s C) at night. Precipitation levels vary greatly from island to island; on Mahé, annual precipitation ranges from 90 inches (2,300 mm) at sea level to 140 inches (3,560 mm) on the mountain slopes. Humidity is persistently high but is ameliorated somewhat in locations windward of the prevailing southeast trade winds.

Ethnic groups, languages, and religion
The original French colonists on the previously uninhabited islands, along with their black slaves, were joined in the 19th century by deportees from France. Asians from China, India, and Malaya (Peninsular Malaysia) arrived later in smaller numbers. Widespread intermarriage has resulted in a population of mixed descent.
