How long are the queues at the Basilica Cistern entrance?
The Basilica Cistern is one of Istanbul’s most popular historic sites, welcoming around 2 million visitors a year. On busy days, queues form along Yerebatan Caddesi well before opening and can extend down Yerebatan Caddesi and towards Hagia Sophia on the busiest days.
Peak season (April–October):
– Walk-up visitors buying tickets on site typically wait around ~40–60 minutes, especially between 11am and 2pm.
– On weekends and public holidays, waits can stretch to ~60–90 minutes during late-morning and early-afternoon peaks.
Off-peak (November–March):
– Ticket-purchase lines are usually shorter, around ~15–30 minutes on regular weekdays.
– Weekends and major holidays can still see waits of ~30–45 minutes, especially in the late morning.
Note: These ranges only cover the ticket / entry queue. All visitors also pass through a separate security check inside the entrance, which typically adds another ~10–20 minutes on busy days.
