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.
There's the town and new city, and the closed part. We were in the closed part.
Honestly, the beach view is fairly representative of what is inside (so unless you a highly motivated, the trip inside might not be worth the risk)
