Grande Comore is the largest island in the Comoros, a volcanic archipelago in the Indian Ocean between northern Mozambique and Madagascar. Mount Karthala, an active volcano and the island's highest point, has a broad crater that visitors can reach on foot with a local guide. Prince Said Ibrahim International Airport is near Moroni, the capital on the southwest coast.
Go for volcanic scenery, a black-sand coast and a slower pace in a small island town. Moroni has a market and historic mosques, and villages nearby sit among clove and vanilla plantations. Comorian is the everyday language, and French and Arabic are official, so a few French phrases help. The dry season, roughly May to October, suits hiking and driving the coast. Allow several days to cover the volcano, the coast and the capital. Day trips to the north coast and to Itsandra are easiest with a driver.
