Sahinderesi Canyon The Sahinderesi Canyon, responsible for the air circulation of the region, distributes mountain pine-scented fresh air to the plain and sea iodine-scented coastal air to higher elevation regions. Thus, Altinoluk town, located close to this canyon, has the second highest oxygen concentration level in the world. The 27-km long canyon which provides reciprocal air circulation is 600 m high.The herbal oasis is decorated with a variety of herbs and plants that heal sore muscles and promote relaxation. The canyon can only be accessed by permission from the General Directorate of Nature Conservation and National Parks. Derecati is a small lake on the road, so remember to take your bathing suit and towel. The region, which only allows the sound of water and birds, is rife with springs. Derecati Spring carries the fragrance of flowers and thyme unsurprisingly as it shoots from mossy rocks. An additional spring called Naneli Spring flows through mints nearby. The Gucuk Burun, Aglayan Cam, Kestane Stream, Yoruk Spring, Selvili Mezarlik, Ayi Kapilar and Damla are interesting geologic features of the magnificent canyon.
