Visiting Istanbul
A city spanning two continents across the Bosphorus, layering Byzantine and Ottoman history with a large, modern metropolis. Few cities anywhere let you cross between Europe and Asia on a short public ferry ride.
Best time to visit: April to May or September to November, avoiding the summer heat and crowds.
Landmarks & highlights
- Hagia Sophia
A former Byzantine cathedral and Ottoman mosque, now open to visitors, with a vast domed interior.
- Blue Mosque
An early 17th-century mosque known for its six minarets and blue Iznik tile interior.
- Grand Bazaar
One of the world's oldest and largest covered markets, with thousands of shops.
- Topkapi Palace
The former residence of Ottoman sultans for roughly 400 years, now a museum of imperial treasures.
Local tip: A short Bosphorus ferry ride is one of the easiest ways to see the city from the water and cross between its European and Asian sides.
Getting around: Istanbul's tram, metro, and ferry network together cover the historic peninsula and both sides of the Bosphorus well.
Good to know: Dress modestly and expect to remove shoes when entering working mosques like the Blue Mosque — headscarves are provided for women if needed.
