Going to Cuenca and not going to see the Casas Colgadas is like going to Paris and missing the Eiffel Tower. It is, without a doubt, its most representative monument. I am one of those people who believe that it is one of those monuments that you see better from a distance, since it allows you to appreciate how the houses have remained through time, as well as that they are standing on the edge of a ravine, like the one in Huecar River.
In order to see them, I recommend moving through the ravine, along its roads and viewpoints, as to appreciate the verticality of these buildings. You shouldn't let the heights impress you when you cross the bridge across the gorges, which moves with the flow of the tourists, and should take the opportunity to take a few pictures of the Casas Colgadas from there.
