Sakarya or Adapazari is a province in Turkey located on the northern coast of the Black Sea and it is bordered by Kocaeli to the west, Bilecik to the south, Bolu and Düzce to the east.
Lake Sapanca is a scenic and charming site that can be reached from Adapazari after driving 5 kilometers south. This enclosed spot offers panoramic views, water sports opportunities, and fine accommodation options.
To the north, Karasu lies another attractive holiday resort. These golden sandy beaches and touristic areas are 67 kilometers from Adapazari on the Black Sea Coast. Akyazi, 29 kilometers away is an outstanding thermal cure center for many diseases besides its strong Geyve (Tarakli) thermal springs.
The area of Sakarya is rich with history stretching back to 378 BC. There are many visible remnants of the Roman and Byzantine Empires, including the Justinian Bridge, built in AD 533 by Eastern Roman Emperor Justinian I. It is a 429-meter long, eight-arched bridge that spans over the Beş Köprü Çayı river and is an interesting sight for those who love historical sites.
