I was in the area last year. You can take a taxi from the Greek side and they will give you a tour of the new city and an archaeological site. The driver was originally from a village not far from there and knew the parts. I doubt you can go in the old parts (there are fences, roadblocks and guards) but there’s a beach from which you have a good view. The closest buildings are only a few meters away. I didn’t take any photos. As a Greek I was a little apprehensive of going there, but most of my Cypriot friends have no problems visiting or driving through the occupied parts.
