Homer called it the most-besieged city in the ancient world, and you can stand inside those walls in a single day from Istanbul. A guided Troy day trip covers the full archaeological site with lunch, hotel pickup, and entrance fees included, making the longest history day trip from Istanbul worth every hour of Dardanelles road time.
An early hotel pickup leads to lunch in Eceabat before the guided walk, which moves in order from the movie replica of the Trojan Horse to the sacrificial altars, the old city walls, the early houses of Troy I and the agora. The evening return closes a day for travellers who want the legend explained through excavated stone.
