Definitely the place to visit when in Cappadocia! We visited at the end of the day (just before 6pm) and were the last people to be admitted. As such we did not have much time to spend, however, we were not met with congestion and loads of tourists around and we got great sunset views! We decided to get a tour guide for 25 euros (discounted price as we were last and he would not be spending much time with us) who was courteous and eager. Nevertheless, I have to admit his knowledge was not extending beyond the information we could find on the signs outside each monastery, church and monument. So it was a little waste of money, but a great company nonetheless! Tips: (1) go either first thing in the morning or last thing in the afternoon - but allow yourself time for visiting all places of interest. (2) do your research with hiring a tour guide and ensure you find someone knowledgeable with good reviews online. The price can always be negotiated on the spot depending on the type of tourist you are - wanting pics and a story for your friends and family or wanting the full blown historic facts tour with a bit of the rest too! (3) DO NOT TAKE PICTURES IN CHURCHES WHERE NOT ALLOWED- I could not stress enough how hostile the staff/security are when they see you holding a phone, camera upon entry. We had a terrible experience with a particular security staff who did not speak a word of English and was shouting and threatening us for making the mistake of walking in with the camera on after taking pics outside. They are rude, (clearly) dislike tourists (and their job as they appeared bored to say the least) and you won't be able to win an argument with them. (4) wear comfortable shoes as some of the points of climbing are slippery. Comfortable clothing and a hat are also recommended. Take your bottle of water too as there is a cafeteria only at the entrance/exit.
