The view from the top is beautiful. The ruins themselves are quite interesting and quite large but it was the view that really made an impression. There were also alpacas there that we could watch and even pet (they didn't really like it but were nice enough to tolerate it). From there you can also walk up to Cristo Blanco - the statue of the white Jesus Christ that's visible from almost anywhere in the city. It looks smaller from up close but very nice to see. Best bet is to buy the Tourist Ticket ahead of time- you can't just pay for this alone it's part of a package. We didn't know that and were hesitant to spend the money for the ticket to see all of them since we were leaving the next day. However, we got there quite late and a local resident offered to drive us up there for half the price of one ticket. He lives in the community and can enter for free. I'm sure it's not quite legal but it's a way for him to make a living I suppose. It worked great for us. We got in for much less and didn't have to walk. We didn't plan to go there- just happened to be close after wondering the city- otherwise we would have bought tickets. It's well worth it.
