Mauritius with its capital, Port Louis, is a volcanic island. The island is surrounded by a coral reef and lined by a few long stretches of white sand beach. It has no active volcanoes unlike neighbouring Réunion, although remnants of volcanic activity – such as Trou aux Cerfs crater in Curepipe and millions of lava boulders can be found. It’s situated in the Indian Ocean, roughly 220km (135 miles) north-east of Réunion, and 800Km (500 miles) east of Madagascar, 3860Km (2400mi) south-west of India. As a country, it includes the inhabited island of Rodrigues, some 560Km (350mi) to the north-east, and other scattered coral atolls such as Cargados Carajos and Agalega.
