Marmara Ereğlisi occupies a triangular peninsula with a ‘hook’ attached on its tip on the northern coast of the Sea of Marmara. In the past, the town was known as Perinthos and subsequently as Herakleia, out of which modern name derived. The town is locally known as Ereğli, and Marmara, although an official part of the name, serves as a disambiguator to differentiate the town from other two Ereğlis in Turkey.
Although older parts of the town resemble more of a village today, with roosters crowing here and there, during the days of Perinthos, town served as the capital of Roman province of Thrakia, and it’s hard to believe but what is today Istanbul was just a village administered from Perinthos then.
Buses operating between Istanbul and Tekirdağ (and other places west lying on this route such as Malkara, Keşan) accept passengers to Marmara Ereğlisi, but you have to get off at the junction of the highway and access road to town centre (which is not a very big deal since you can walk to town centre in about 15-20 minutes at most). Minibuses from Tekirdağ’s otogar on the other hand make it all the way to the town centre.
Despite being a coastal town, there are no scheduled ferry services to the town and quite frankly there is not somewhere suitable to anchor if you even arrive by your own boat. You may better anchor your boat in Tekirdağ and then bus the rest 40 km overland instead.
Walk. Nowhere in the town is away more than 15 minutes of walk from each other.
The ostentatious days of Perinthos are long gone for more than two millenia, so many of the historical sights described here are slowly vanishing. In fact many can be distinguished from natural formations only by careful eyes and only people really interested in history may find them worth of a check.
As soon as you enter the town, you’ll see lots of signs for hotels (otel) and guesthouses (pansiyon). Some may be closed for winter, however, there are ones open year-round on the eastern waterfront.
If you are into camping, you can find some good and discrete spots away from houses to pitch your tent near the southern coast of the peninsula, over the cliff on the way to amphitheatre. Aim for areas covered with wild grass, not wheat fields or other cultivated places.
There are lots of stray dogs around (particularly in winter). The worst they are capable of doing is barking at you and giving a little chase it seems, though.
