Hotels in Kocaeli Province, Turkey

Kocaeli Province sits in northwestern Turkey, straddling the Sea of Marmara and the Black Sea, with a climate that brings mild, rainy winters (40-50°F / 4-10°C) and warm, humid summers (70-85°F / 21-30°C). It's famous for its industrial history and natural escapes - you can explore Roman ruins in the old capital Nicomedia during the cooler months, then hike Ballıkayalar Nature Park in spring when the waterfalls are full. In summer, the Black Sea coast at Kefken Island offers swimming and fresh seafood, while autumn is perfect for biking through the Samanlı Mountains' colorful forests.
