The highlight of the D915, between Bayburt and Çaykara, is known as Derebaşı Turns. This 5.1 km (3.2 mi) stretch has 13 steep hairpin turns, rising from 1,712 m (5,617 ft) to 2,035 m (6,677 ft) above sea level. With gradients up to 17%, this gravel road is dangerous but offers breathtaking mountain views for those who dare to take it on.
