Istanbul Gay Tours runs private tours of the city for LGBT+ visitors, with gay or gay-friendly licensed guides. It is a registered member of the Association of Turkish Travel Agents.
The Istanbul programme covers the obvious things, Hagia Sophia, the Blue Mosque, Topkapı Palace, the Basilica Cistern and the Grand Bazaar, and some less obvious ones: a Bosphorus trip by yacht or public ferry, a culinary tour that crosses between the European and Asian sides, an off the beaten path route, and a nightlife tour that takes in the Taksim bars. There is also a layover tour for people with a few hours between flights.
Beyond the city they run trips to Cappadocia, the balloon flights included, and longer packages elsewhere in Turkey. Everything is private rather than group, so the route can be rearranged.
