Cunda and Lale islands are linked to Ayvalık on the mainland, by a causeway enabling transportation by car.

Cunda also has a ferry link from the main town, Alibey, to Ayvalık during the summer.

A Greek Orthodox metropolis was established, based in Cunda island, for some months in 1922.

Although being geographically separate from the archipelago, it is grouped with other islands as all of them are part of Ayvalık district.

The Greek name has different spellings of the former, such as 'Εκατόνήσος Hekatonesos, Εκατόνησοι Hekatonnesoi or Εκατός Hekatos, and yet another name exists altogether, i.e., Ἀπολλώνησος Apollonesos, the "Isle of Apollo".
