Grande Comore

Grande Comore is a volcanic island in the Indian Ocean, dominated by Mount Karthala, an active volcano rising 2,361 meters (7,746 feet) above sea level. Coastal settlements have developed around its base, connected by a single main road that circles the entire shoreline.

The island was originally divided into ten separate sultanates before Sultan Saidi Ali ibn Saidi Omar unified it in 1886 under French protection. This consolidation shifted the territory from fragmented rule to a centralized administrative structure.

The people here practice Sunni Islam and speak Comorian, Arabic, and French, reflecting centuries of maritime trade connections. You hear this linguistic blend throughout daily life, from markets to mosques in the coastal settlements.

The island has an international airport in Moroni, which is the main entry point for visitors arriving by air. A single circular road connects all coastal settlements, making it straightforward to travel between different areas of the island.

The island has no permanent rivers or streams because its porous volcanic rock allows rainwater to filter directly underground. This geological feature shapes how residents manage water and use the land.
