"The twin valleys of Soganli...look so magical that mischievous guides have falsely claimed that they featured in Star Wars. Yoda is not snoozing in any of the rock-cut churches, but...Soganli is a magnificent place to explore...and you may well have the valleys to yourself." Lonely Planet Guide to Turkey. Indeed, we did. Our French-speaking guide Ozgur, a resident of the area, had a car, knew the history in detail and knew where to go.
The twin valleys "were first used by the Romans as necropolises and later by the Byzantines for monastic purposes, with ancient rock-cut churches," Lonely Planet reports.
