We explore both sides of Istanbul with friends. Find a base near Sultanahmet’s historic sights or Kadıköy’s markets, then plan a walk, a ferry crossing or breakfast close to where you’re staying. Make the Bosphorus crossing part of your day. Check your departure pier and the return service before heading to Kadıköy, and pick metro or tram connections to suit your route. On get-togethers when we take the club minibus, the ride is free. We decide together where to stop.
