Lake Dziani
Dziani is a vivid green crater lake on Petite-Terre, a reminder of Mayotte's volcanic origins. It covers about 17.5 hectares, is relatively shallow on average and is encircled by a marked trail along the crater rim. The circuit offers simultaneous views of the green water, lagoon, Papani and Moya beaches and the open Indian Ocean.
When to go
The official tourism portal particularly recommends the period after the rainy season, approximately April to July, when vegetation is green and walking is usually more pleasant. The heaviest rain falls from late November to early April. Start early in the morning to avoid heat, and abandon the walk during heavy rain or thunderstorms.
Things to see and do
Walk the marked circuit around the lake, which takes about an hour, and stop at viewpoints between the crater and ocean. Afterwards, options include Moya or Papani beaches, historic Dzaoudzi and the Musée de Mayotte. A microlight flight reveals the crater's shape and lagoon from the air.
Practical tips
Swimming in Lake Dziani is strictly prohibited: its water has an alkaline pH of about 9 and is considered caustic and dangerous. Do not leave the marked path or approach the water down unstable slopes. Sturdy shoes, water, a hat and sun protection are necessary; the ground becomes slippery after rain. Do not disturb turtles on neighbouring beaches.
Getting there and getting around
Mayotte's airport is in Pamandzi on Petite-Terre, so the trailhead is a short car or taxi journey via Labattoir towards Totorossa and Route des Badamiers. Ferries run regularly between Mamoudzou on Grande-Terre and Dzaoudzi. Park at the trailhead only in authorised areas.
Where to stay
Dzaoudzi, Labattoir and Pamandzi on Petite-Terre are particularly convenient for the lake, with guesthouses, small hotels and restaurants. Mamoudzou offers more services but requires a ferry crossing. Check the current operation of accommodation and transport before travelling.
What to try
Try mataba made with cassava leaves and coconut milk, spiced pilao rice, grilled fish, seafood, mabawa and banana or cassava dishes. Mayotte's cuisine combines Comorian, Malagasy, East African, Arab and French influences.
