Broadly safe for most visitors, with only routine travel precautions needed. Public health and infrastructure are well developed.
Regional breakdown
Mayotte is a small French overseas department in the Indian Ocean, made up of two main islands. Grande-Terre holds most of the population, the airport gateway at Dzaoudzi sits on Petite-Terre, and the capital Mamoudzou is the commercial and administrative hub. A short ferry crosses the lagoon between the two islands many times a day. Mamoudzou and its outskirts see the highest reports of street crime, including bag snatching and break-ins. Travellers who stay here should keep valuables out of sight and avoid walking alone after dark. The neighbourhoods around the central market and the ferry terminal are busiest and need the most care. Grande-Terre's quieter west coast, around Sada and Chirongui, is calmer and popular for lagoon trips and turtle watching. Petite-Terre, including Dzaoudzi and Labattoir, is the main entry point and feels more orderly. But services there were hit hard by Cyclone Chido in December 2024 and recovery is still uneven across the island.
Recent advisory changes
The official advisory guidance last updated its Mayotte page on 10 December 2025. The latest change covered new entry rules for dual nationals returning to the UK. It also flags the cyclone season, which runs from December to April. And notes that water and electricity outages can still happen in places following Cyclone Chido. The official advisory guidance does not publish a separate advisory for Mayotte. It is covered by the France advisory, which sits at Level 2, Exercise Increased Caution, and was reissued on 28 May 2025. That notice focuses on terrorism risk and pickpocketing in mainland France. It lists several French overseas territories with their own guidance but does not name Mayotte. Travellers should treat the France notice as the baseline and read the UK page for island-specific detail.
What travellers should know
Plan for thin infrastructure. Some hospitals, shops, and utilities are still recovering from Cyclone Chido, so book accommodation that has back-up power and water where possible. Carry cash, as card terminals can fail during outages, and keep a few days of bottled water and basic supplies in your bag. Check the latest from Meteo France during cyclone season before any inter-island ferry or boat trip. Petty theft is the most common issue for visitors, so keep phones, passports, and bags close in Mamoudzou and at the ferry terminal. Avoid walking through unlit areas at night and use registered taxis after dark. French driving rules apply, and an international driving permit is often needed for hire cars. If you plan to dive or sail, check the operator's insurance and equipment carefully. And stay well clear of the wider Indian Ocean piracy zone north of the Mozambique Channel. Register your trip with your embassy and keep travel insurance that covers medical evacuation, since serious cases are often flown to Reunion or mainland France.
