Osmaneli is a town in the Eastern Marmara region of Turkey, in the valley of the Sakarya River, with a population in 2020 of 15,598. The reason to visit is for its old town, with many traditional buildings.
Osmaneli formerly had a large Greek population and was known as Leukai or Lefke, meaning "poplars". The Sakarya river is not navigable but carves a valley through the hills. The town was therefore on one of the overland trade routes towards Constantinople / Istanbul from the plains of Anatolia, and silk was cultivated here.
Modern routes passed far to the north and the town became a backwater, though this helped to preserve its old architecture. Much of this was lost in the great fire of 1874, but some has been saved or restored. Osmaneli today makes its living from agriculture, especially from fruit & veg cultivated along the valley.
By car follow D650 between Adapazarı and Bilecik. From Istanbul follow O-7 (toll) to Adapazarı to join D650 southwards.
Osmaneli is difficult to reach by public transport - the inter-city bus lines don't come this way. You might need to travel via Bilecik 35 km south, which has YHT high speed trains every hour or two between Istanbul, Ankara and Konya. A bus runs every hour or two between Bilecik and Osmaneli, taking 45 min.
A bus also runs every two hours from Iznik, taking 40 min.
Osmaneli lost its railway service in 2020, which is unlikely to resume. The axe was already hovering over the Boğaziçi Ekspresi before the onset of Covid, as the YHT line takes a different route and the old railway was seen as redundant. The disused station is in the northeast corner of town: nearby cafes have folded.
Walk: the old town is 500 m west of the main bus stop on Ankara Cd.
Cyclists who want to test their mettle can try the hairpin road southwest up to Balçıkhisar.
There's a cluster of cheap eateries in town centre south of the main street. They include Tadım Döner, Kuzular Caybahcesi, Uğur Salonu, Teyyare Meydan Lokantası, Kardeşler lokantası, Ünsa Salonu, Hacıalioğlu Çiğ Köfte, Karadeniz Unlu Mamulleri, and Nefis Pide Lahmacun.
Many restaurants and cafes serve beer but there isn't a free-standing pub.
Plans to tap the spa waters in the hills have so far come to nothing.
Osmaneli and its approach highway D650 have 4G from all Turkish carriers. As of Oct 2022, 5G has not rolled out in Turkey.
