Addu (also Seenu) is the southernmost atoll in the Maldives. Hithadhoo, its capital, was the base of the short-lived United Suvadive Republic secessionist movement in 1959–1963.
- 1 Gan International Airport (GAN IATA). can be reached from the capital, Male, in a beautiful unforgettable 60-minute-flight over the southern atolls of the Maldives. The are also scheduled flights to some other atolls as well as one international flight to Colombo operated by SriLankan Airlines.
The four islands of Gan, Feydhoo, Maradhoo and Hithadhoo are connected to each other by causeways. There is a bus service which runs daily every two hours (except on Friday morning) all the way from the Gan island up to the north of the Hithadhoo island and back. The bus is reliable but slow, the just 15 km long route takes almost an hour. On the Feydhoo island the bus passes the Feydhoo ferry terminal from where you can take a ferry to Meedhoo. On the Gan island the bus doesn't go directly to the airport but terminates about 500 m away from the airport (to get there walk out of the airport, turn left and walk for about 500 m along the Link Road until you see a building with the label "ASTRA" on the left side of the road, this is where the bus terminates).
