About this place
Istanbul is a city of extraordinary depth, where over two millennia of history unfold across two continents. Once known as Byzantium and later Constantinople, this sprawling metropolis straddles the Bosphorus Strait, linking Europe and Asia. With a population exceeding 15 million, it serves as Turkey’s cultural and financial heart.
From the iconic domes and minarets of the Sultanahmet peninsula to the vibrant modern streets of Beyoğlu, Istanbul rewards exploration at every turn. Ancient empires, a medieval metropolis, and a dynamic modern Middle Eastern hub all coexist here, making it a destination where you can truly feel the layers of time.

Things to Do
- Classic Bosphorus cruise — Take a public ferry from Eminönü to Anadolu Kavağı near the Black Sea entrance. You can explore the ruins of Yoros Castle and enjoy waterfront seafood before the return trip.
- Visit a historic hamam — Sultanahmet is home to several centuries-old bathhouses. Some are lavish and cater more to tourists, while others retain a deeply traditional, local atmosphere.
- Walk the Theodosian Walls — Trace a 7-km stretch of these ancient land fortifications marking the old city’s western border, with accessible sections, towers, and the well-preserved Yedikule Fortress at the southern end.
- Smoke a nargile — Enjoy a water pipe in atmospheric courtyard cafés near the Grand Bazaar or along the Golden Horn waterfront; a relaxing pause with a distinctly local flavor.
- Attend a football match — The intense rivalry among Beşiktaş, Fenerbahçe, and Galatasaray makes for an unforgettable, high-energy experience, but be careful not to wear away colors on match days.

Things to See
- Sultanahmet Square — The historic core of the old city, where you’ll find the Hagia Sophia, Blue Mosque, Topkapı Palace, and Basilica Cistern within a short walk of each other.
- Galata Tower & Beyoğlu — Climb the tower for panoramic views, then stroll down İstiklal Avenue, the city’s famous pedestrian thoroughfare, lined with shops, galleries, and historic passages.
- Kariye Mosque (Chora Church) — A quieter masterpiece near the city walls, its interior is entirely covered in glittering Byzantine mosaics and frescoes.
- Eyüpsultan district — Home to one of Islam’s holiest shrines in the city, this area offers cobblestone lanes, traditional dress, and a vivid sense of Ottoman Istanbul’s daily rhythm.
- Bosphorus waterfront palaces — The European shore is dotted with opulent 19th-century palaces (Dolmabahçe, Beylerbeyi) and elegant wooden yalı mansions, best viewed from a ferry.

Best Time to Visit
- Late spring (late May to early June) — Mild, pleasant temperatures and less rain than winter make for ideal walking weather. The city is green, and the famous tulips may still be blooming in April into early May.
- Early autumn (late September to early October) — Similar to late spring, these weeks offer comfortable warmth, fewer crowds than summer, and a lower chance of the heavy showers that characterize later autumn.
- Summer (July–August) — Expect the warmest weather with highs averaging around 26°C. This is the busiest tourist season; book accommodation well ahead, and expect crowded sites and higher prices.
- Window of best travel conditions (May 12 – Sep 28) — This period provides the most reliable mix of warm weather, sunshine, and lower rainfall, with typical temperatures from a mild 8.5°C to a peak of 35.3°C.

Planning Tips
- Get an İstanbulkart — A reloadable transit card is essential for discounted fares on trams, metros, ferries, and buses. It pays for itself within a few rides and avoids the hassle of single-use tickets.
- Dress for layers and variable weather — Even in summer, evenings can cool down enough for a light jacket. Winters require warm, windproof clothing, and an umbrella is useful year-round due to sudden rain.
- Verify prices before ordering — In restaurants and cafés without printed menus, always ask for the price to avoid being overcharged. Be wary of multi-language menus with handwritten numbers.
- Use official taxis with a meter — Insist the taximeter (taksimetre) is running, and if possible, have your hotel call a reputable cab. For airport transfers, the Havaİst bus or M11 metro are safer, fixed-price alternatives.
- Watch for closing days — Many museums and monuments are closed on Mondays or Wednesdays rather than fully open daily. Check schedules online before heading out to avoid a wasted trip.
