This valley is situated near Yesilhisar in the province of Kayseri, 40km southeast of Urgup, and 25km to the east of Derinkuyu.
Fractures and collapses during earthquakes have added to erosion resulting in deep valleys and canyons.  Soganli valley, which is divided into two, has been occupied since the Roman period.  The rock cones found on the sides of the valley were used as graves by the Romans, and later as churches by the Byzantine.  The frescoes in the churches date back to the 9th and 13th centuries.

Important churches in the valley are Karabas, Yilanli, Kubbeli and the Church of St. Barbara (Tahtali).
