It´s located about 20 minutes away from Cuenca by car, the road to get there is Initial D worthy, and has beautiful views too. I don´t really know but i guess there are probably buses from Cuenca in the case you don´t have a car avalible.
In the way there you can stop in a awesome natural viewpoint called "Ventano del Diablo" (Window of the devil), and enjoy nice views of the Jucar river.
In the way there i had a little "SnW moment" when i noticed i forgot to get new batteries for the camera, so i decided to drive to the next town in order to get some. I got a but angry on the way there, but once i got there and found this beautiful lake everything went peacefull again.
Accessing the "Ciudad Encantada" will cost you 3€, but i think it´s well worth it. The place it´s been Tourist fixed, and the whole walk in there is marked and gravel paved, it´s about a hour and a half walk depending on your speed and interest.
To be fair, i really didn´t find much SnW direct clues here, but the enviroment reminded of some of the surroundings of Seize we get to see. But there was something i did reconogize.
This is the first rock in the walk, and the one that we can see in the series, but in real life there´s only one, instead of seceral of them together. The rest of the Ciudad encantada is basically rocks that have taken the shape of animals and objects. Here´s some of them.
Elephant Vs. crocodile
Most of these are a case of "Doesn´t work of picture", but with a bit of imagination, they really take shape.
This is the sort of place you´s love when you are 10.
I´d love to walk through here after a huge snow fall, it must be incredible.
This wasn´t really into the marked walk, but i jumped up out of curiosity and found this, the sea of rock...
Anyways, it´s great relaxing walk. I did it first thing in the morning, mostly alone and had a great time.I strongly suggest you to avoid heat hours, and specially tourist hours, because they will ruin the experience, because this is meant to be done as silently as possible.
