Istanbul Tours 2026 — Best Itineraries, Costs & Local Tips
Hagia Sophia, the Bosphorus, the Grand Bazaar — and the parts of Istanbul travelers usually miss.
Istanbul is the only city in the world built across two continents, and its 8,500-year history is layered into every district you walk through. The Hagia Sophia (537 AD), Topkapı Palace (1465), the Basilica Cistern (532 AD) and the Süleymaniye Mosque (1557) sit within a 20-minute walk of one another in Sultanahmet — a density of UNESCO-listed sites no other European city can match.
