The Solor Archipelago is located in the eastern Lesser Sunda Islands off the eastern tip of Flores Island. It is divided from its close neighbour to the east, the Alor Archipelago, by the Alor Strait which connects the Banda Sea in the north to the Savu Sea in the south.
The main islands of Solor, Adonara and Lembata (previously known as Lomblen) are surrounded by many smaller islands. Sitting directly on the Sunda volcanic arc, the islands of Solor are mountainous with rugged coastlines interspersed with rocky headlands, secluded coves and long sandy beaches.
