Princes’ Islands— a getaway from crowded Istanbul featuring pine-covered islands with elegant mansions
This region gets its name from the sea it surrounds: the Sea of Marmara, a part of Mediterranean Sea, connected to Aegean Sea via Dardanelles, and to Black Sea via Bosporus. The Sea of Marmara is considered as the geographical border between Europe and Asia: northern coasts of it are in Europe, while southern/eastern coasts are in Asia.
This region is Turkey’s most populous and most heavily industrialized part, though you can still find primordial forests hardly seen by human eyes here and there.
Atatürk International Airport (IST) in westernIstanbul is the main gateway for the city, the region, and the country as well. The other international airport in the region is Sabiha Gökçen (SAW), situated in eastern Istanbul, largely prefered by low-cost airlines. Corlu Airport (TEQ) is used by airlines flying from ex-USSR countries. Other airports in the region are located in Bursa and Canakkale.
All cities and many towns in Turkey has direct daily bus services to Istanbul. Many cities neighbouring Balkan countries also has bus links to the city. Bursa, by virtue of being a big city, is also served from a large number of cities and towns throughout Turkey.
Marmara Region is well linked to neighbouring regions and countries by a motorway and highway network.
There is a weekly ferry service to Istanbul from Izmir during summer months.
While there are more than one airport in the region, given the region's relative small size and the relative short distance between the airports make transportation by plane practically impossible. The only feasible (and, operating) air service totally within the region is between Istanbul and Canakkale.
There is an extensive bus network between towns and cities of the region, and any town with a considerable population (say, >10,000), has a direct bus service to Istanbul.
There is an extensive network of ferry and fast ferry lines connecting northern and southern coast of the Sea of Marmara, cutting travel time dramatically. Most fast ferry lines fan out of Istanbul towards towns and cities on the southern coast, while conventional ferries can be found between almost any town on the northern and southern coasts (such as Tekirdağ-Gemlik line, which traverses almost the whole sea northwest to southeast).
