Wine tourism in Eastern Crete is being developed in the areas around Heraklion (Wine Roads of Heraklion) and Lasithi. In Lasithi, at the eastern end of Crete, the vineyards are located around the town of Sitia, and to the south and at a higher elevation, on the Ziros plateau. The Protected Designation of Origin (PDO) Sitia wines are produced in the Sitia vineyards. The Kazarma Fortress and the archaeological museum in Sitia, the Minoan settlements of Petras and Mochlos, the Minoan city in Palekastro, Toplou Monastery and its museum, the palm tree forest in Vai and the Minoan palace in Zakros are just some of the sights worth visiting in the general area of Sitia. However, the sights of Lasithi are not limited to its eastern wine-making region; visitors can see the town of Agios Nikolaos and its archaeological museum, Elounda, with the wind mills and island of Spinalonga, the ancient city of Lato, the archaeological collection of Neapoli, the Minoan manor in Makris Gialos, the archaeological site of Gournia and the archaeological collection in Ierapetra, Dikteon Andron (Psychro Cave) and the wind mills on the Lasithi plateau.
