I am going to be in Cappadocia next week and want to do a day hike so I can take some nice sunset photos. I read that Red Valley will provide some spectacular views during the sunset. Where does the trail start and approximately how long is the hike to the best views during sunset? I want to make sure I have enough time to hike back to civilization! And if you have any other recommendations for great views during the sunset (for optimal lighting for photographs), please share! Thanks.
