It’s possible to rent cars on Grand Comore for approximately CF15,000 to CF25.000 (€30 to €50) a day, depending on the type of car. In Moheli there are no rental agencies, but still you might try to rent a car or motorbike directly to a local with the help of your hotel. Petrol price varies from island to island. While you may pay CF600 (€1.2) per litre in Grand Comore, the price in Moheli (where petrol is scarce) can rise up to CF1000 (€2) per litre.
Each island has a mainroad around the island. Road conditions can be really bad on certain sections, but still doable by regular vehicles without 4WD.
Hitch-hiking is a very common practice among locals, specially in Moheli were there are fewer transportation options. If you look like a tourist, some fee may be requested. As the locals have no access to public transport and children have to walk to and from school, tourists with a car may wish to consider aiding hitch-hikers.
BY PUBLIC TRANSPORT:
Each capital is connected by bus with the villages on their respective island main road. Buses are usually packed, have no fixed schedule and stop running well before sunset.
Shared taxis are the most common mode of public transport within cities.
Speedboats operate from Chindini on the southern coast of Grand Comore, to Hoani on the northern coast of Moheli. These boats are small fibreglass fishing boats with boat and engines in variable condition. They should be taken only on days when the sea is calm, as passengers have been forced to off-load baggage into the sea and there are rumours boats being lost. However, these boats are generally safe to take on calm days. It is anyway always wise to ask for a life vest. Boats depart from Chindini every morning and the trip takes about one hour. The price is CF10.000 (€20) as of November 2008, plus an additional CF500 council departure tax. Some tourists have been requested a special permit from the police.
Cargo vessels covering the route between the three island’s capitals also accept passengers. You’ll have to ask at the port or find an agency, and expect longer travel times (up to 12 hours from Moroni to Moheli). The price from Moroni to Fomboni in Moheli is CF10,000 per person.
The company Maria Galanta operates the route Moroni—Moutsamoudou (Anjouan)—Dzaoudzi (Mayotte) twice per week. As of October 2018, the boat leaves from Moroni Thursdays and Sundays, and return trip is Wednesdays and Saturdays. Duration of each leg is 5 hours. The price to Anjouan is €36 one way, and €140-158 all the way to Mayotte. Maximum baggage allowance is 20 kg plus 10 kg of hand baggage.
