Language
French is the official language and essential for getting around. Shimaore (a Bantu language related to Comorian) and Kibushi (a Malagasy dialect) are widely spoken in local communities. English is rarely spoken. A French translation app on your Roamix-connected phone is very useful.

Food & Dining
Mahorais cuisine blends African, Comorian, Malagasy, and French influences. Look for poulet au coco (chicken in coconut milk), mkatra foutra (coconut flatbread), and grilled fish in Mamoudzou waterfront restaurants. Fruit markets offer unusual tropical varieties.
Transport
The barge ferry between Petite-Terre and Grande-Terre is the island lifeline. Ferries depart every 30 to 45 minutes from early morning until late evening. Use Roamix data to confirm the last ferry times from Mamoudzou before planning your evening.
