How to avoid the worst of it today

Spend your first two hours on Sultanahmet's giants. Hagia Sophia at opening, then the Blue Mosque between prayers — the two heavyweights before the tour waves converge on the square between them. Booked tickets turn the day's biggest unknowns into appointments. When a city's queue-beasts stand on one square, dawn there is worth more than any afternoon trick.
Go underground or across the water at the peak. Midday belongs to the cistern's timed dark, the museum halls, or better: a ferry across to Kadikoy for lunch on the Asian side while the old city runs its hottest, thickest hours.
Bazaar late, Bosphorus last. The Grand Bazaar mellows toward closing; the Spice Bazaar pairs with the New Mosque and the bridge at dusk. End on the water — the skyline at golden hour is what you came for, whether by public ferry or a proper cruise.
Know the prayer times before you plan the day. The mosques close to visitors five times a day, longest at Friday midday. It is the one Istanbul timing rule that outranks every crowd pattern on this page.

Where the crowds are

Sultanahmet Square & its two giants: The lawn between Hagia Sophia and the Blue Mosque is the reference crowd of the city.
The Grand Bazaar's main arteries: The spine lanes jam when groups sweep through; side alleys stay workable.

Quiet places in Istanbul

Suleymaniye Mosque & its terrace: The great Sinan mosque above the Golden Horn — majestic and consistently unhurried.
The Asian side — Kadikoy & Moda: A twenty-minute ferry from the crush, and the city's best eating streets.
