How long are the queues at the Topkapi Palace entrance?
Topkapi Palace is one of Istanbul’s most-visited landmarks, drawing over 3.4 million visitors a year and up to ~20,000 a day in summer. On busy days, the longest wait is usually at the ticket booths, not security.
In peak season (roughly June to August and holiday weeks), on-site ticket lines can stretch to ~45–60 minutes between 10am and 2pm, especially after the Tuesday closure when many visitors show up on Wednesdays.
In shoulder and low season (roughly November to March), waits for tickets often drop to ~10–30 minutes, though late mornings and weekends still see steady queues.
After tickets are scanned at the Gate of Salutation, all visitors go through airport-style security. That line usually adds another ~10–25 minutes during busy hours, and ~5–10 minutes the rest of the day.
