Istanbul Travel Guide 2026

Istanbul is unlike any other city on earth. Straddling two continents — Europe and Asia — across the shimmering Bosphorus Strait, this ancient megalopolis of 16 million people has been the capital of three world empires: Roman, Byzantine, and Ottoman. The evidence is everywhere, from the soaring dome of Hagia Sophia to the labyrinthine Grand Bazaar, from Byzantine mosaics to Ottoman minarets.

But Istanbul is emphatically not a museum. It's one of the world's most vibrant, creative cities — the food scene rivals Paris and Tokyo, the nightlife stretches from rooftop bars to underground clubs, the café culture on the Asian side is legendary, and the art scene centred on Beyoğlu is exploding. This is a city that simply never stops.

For British travellers, Istanbul from the UK is an easy 3h 45m flight with multiple daily direct services — and the pound stretches remarkably far. This 2026 guide covers everything you need to plan the perfect Istanbul visit, from must-see sights to the best Istanbul hotels and cheapest flights from UK airports.
