You can get to the Museum of Troy and the excavations by minibus, which does not run so often, or by car. The fare is 75 lire. Entrance to the museum (brown cube) 27 euros. And if you are a family, then this is an exorbitant amount! If you trot, you will get to the excavations, which leave more positive emotions. The ticket office is located next to the entrance to the museum and is quite far from the excavations. There are only parking spaces nearby and not a single bench. You will not see a Trojan horse, or maybe you will be lucky and a new one will be put together by your arrival. Where is the one that you can climb into - we have not found. Maybe he's far away on the road to Troy.
The Museum of Troy is much more interesting than what remains of the city. If you are not an archaeologist or a historian, then there is absolutely no need to pay a lot of money to visit Troy itself. These are just paths among piles of stones, with inscriptions where everything was and in what century. You will be able to learn and see much more in the museum. The exposition occupies 4 floors (if memory serves me correctly) with examples, artifacts, interactive stands, very modern about the old days!!! In short, if you choose what to spend money on, I would definitely choose a museum, since there are still a huge number of more interesting ruins than Troy on the territory of modern Turkey. (All of this is exclusively my IMHO)
