Since Sapanca is closed to Istanbul and some other cities and has a wonderful lake and other green beauties, it is preferred for short time holidays. The tourism income is increasing especially thanks to the touristic facilities around the lake. Since the facilities in the lakeside were damaged in the 1999 earthquake, the tourism of the county regressed a bit, it has revived recently. There are many holiday villages and summer houses in places like Maşukiye and Kırkpınar.
Another region that has developed recently is Kartepe which is the highest point in Samanlı Mountains and it is close to Maşukiye. By means of the new facilities here, winter tourism is also developing.
