In the vicinity of the village Koz (Sun Valley) there is the Delikli-Kaya rock. It is also called the Three Sisters — this name is associated with an old legend about the rock. There is a through hole at the top of Delikli-Kaya, which explains the name of the rock. Delikli means «full of holes» in Crimean Tatar. People lived in these places more than 3 thousand years ago. At the foot of the cliffs there are wine tunnels, where the famous “Black Doctor” and “Sun Valley” wines are aged.
