Despite it being a really touristy location, there were Ecuadorian families who brought their children there too. At least on the weekends, there are also groups that dance. When we happened to be there on a Saturday morning, there was a fairly large group of children who did some nice dances from indigenous groups in the region.
There is not too much left of the fortress, other than the foundations of a few walls, the foundation and stairs of a main building, and the terraces cut into the hillside. The short video I took standing on the site of the surrounding view simply does not do it justice.
There is another site, called Ingapirca, which is between Quito and Cuenca, that supposedly has the best preserved Incan ruins in Ecuador. I really hope that I get a chance to see that too while I am here.
