Editing Sea of Marmara (section)

===Islands===
There are two main groups of islands in the Sea of Marmara. To the north lie the [[Princes' Islands]], an archipelago made up of the inhabited islands of [[Kınalıada|Kınaliada]], [[Burgazada]], [[Heybeliada]], [[Büyükada]] and [[Sedef Island|Sedef Adası]] and several uninhabited islands including [[Sivriada]], [[Yassıada]], [[Kaşıkadası, İstanbul|Kaşıkadası]] and [[Tavşan Adası|Tavşanadası]]. The inhabited islands are readily accessible by ferry from both the European and Asian shores of [[Istanbul|İstanbul]] and the entire archipelago forms part of the conurbation. 

To the south lie the [[Marmara Archipelago|Marmara Islands]], an archipelago made up of the eponymous [[Marmara Island]] and three other inhabited islands – [[Avşa]], [[Paşalimanı]] and [[Ekinlik Island|Ekinlik]] – as well as of seventeen largely uninhabited islands including the prison island of [[İmralı|Imralı]] whose most famous prisoner, since 1999, has been the PKK leader [[Abdullah Öcalan]]. These islands lie within [[Balıkesir Province|Balıkesir province]] and are most readily accessible from [[Tekirdağ]] in [[Trakya|Thrace]] or [[Erdek]] on the southern shore of the Sea of Marmara. In high summer additional ferries travel to Avşa and Marmara Islands from the centre of İstanbul to facilitate a growing tourist trade.

There are also a few individual islands elsewhere in the Sea of Marmara, such as Koç Adası, off [[Tuzla, Istanbul|Tuzla]], which is privately owned by the [[Koç family]] of industrialists.
