Istanbul
Before you go
Visa
Indian passport holders can't get a visa on arrival. If you hold a valid Schengen, US, UK, or Ireland visa or residence permit, you qualify for Türkiye's e-visa — an online application that takes minutes (single entry, 30 days). Without one of those visas, you need a sticker visa through the Turkish consulate, which means an appointment and weeks of lead time — apply well ahead. Either way, keep proof of hotel bookings, return ticket, and funds (a ~€50/day guideline) handy at immigration.
Best time to visit
April–May and September–October are ideal: 15–25°C, clear light on the water, and the old city is walkable all day. June–August runs hot (28–33°C) and humid with peak crowds at Hagia Sophia and Topkapi. December–February is cold, grey, and sometimes snowy — atmospheric and cheapest, but pack for rain and check ferry schedules in rough weather.
Getting around
Get an Istanbulkart (from machines at any tram/metro stop) and use it for trams, metro, funiculars, and public ferries — the T1 tram alone links Sultanahmet, Eminönü, and Karaköy, covering most of this itinerary. Fares are cheap but change frequently with inflation, so top up small amounts. For taxis, use the BiTaksi or Uber app (both dispatch the yellow taxis) and watch that the meter starts — traffic is brutal, so default to trams and ferries.
Currency
Turkish lira (TRY) — but inflation is high enough that hotels, and many attractions (Hagia Sophia's tourist ticket is €25), quote prices in euros, and those euro prices are what you should budget against. Cards are widely accepted; keep small lira cash for tram top-ups, market stalls, and tips. Exchange at a city-centre döviz office, never the airport counters.
Things to keep in mind
⚠ Taxi meter games
The classic Istanbul taxi tricks: a "broken" meter, a scenic route, or swapping the 50-lira note you handed over for a 5 and demanding the difference. Use BiTaksi or Uber so the route and fare are logged, watch the meter start when you get in, and state banknotes out loud as you pay.
⚠ The shoe-shine brush drop
A shoe-shiner walking ahead of you 'accidentally' drops his brush; when you return it he insists on a thank-you shine — then aggressively bills you for it. It's a decades-old routine around Sultanahmet and Galata Bridge. Point out the drop if you like, and keep walking.
Itineraries
These itineraries assume April–October walking weather. Any time of year, mosques close to visitors around the five daily prayer times — and for longer around Friday midday prayers — so slot mosque visits between them and dress modestly (headscarves for women, no shorts).

Hagia Sophia
Fifteen centuries as cathedral, mosque, museum, and mosque again — nothing else in the city compresses Istanbul's whole story into one building. Tourist entry is €25 and routes you through the upper gallery (the ground floor is reserved for worship); go at opening before the tour groups.

Topkapi Palace
The Ottoman sultans' palace of courtyards, treasury, and Bosphorus terraces — allow a half day, and pay the Harem add-on (it's the best-preserved part). Closed Tuesdays.

Blue Mosque (Sultanahmet Camii)
Free, still a working mosque, and directly across the park from Hagia Sophia — the İznik-tiled interior earns the name. Visit between prayer times, shoes off, dress modestly; the queue moves fast.

Bosphorus public ferry crossing
The commuter ferry from Eminönü to Kadıköy or Üsküdar is the real Bosphorus experience — a between-two-continents crossing with tea served on deck, for the price of a tram ride. It makes the pricey tourist cruises unnecessary.

Basilica Cistern
A 6th-century underground forest of columns (find the two Medusa heads) two minutes from Hagia Sophia — atmospheric and quick. Midday queues can outlast the visit itself; go early or late.

Grand Bazaar
Four thousand shops under one Ottoman roof — worth walking for the architecture and the haggling theatre, but prices target tourists and the hard sell is constant. Browse here, buy your actual souvenirs in Kadıköy or a neighbourhood shop. Closed Sundays.

Süleymaniye Mosque
Sinan's masterpiece above the Golden Horn — grander and far calmer than the Blue Mosque, with a terrace view over the water that's the best free vista in the old city. Ten minutes' walk uphill from the Grand Bazaar.

Galata Tower
The medieval Genoese tower is the icon of the northern skyline, but the paid viewing deck is small, queued, and pricey — the surrounding Galata/Karaköy lanes deliver more per hour. Photograph it from the street; go up only if the queue is short.
Bosphorus dinner-show cruises
Set-menu boats with a stage show, sold hard around Sultanahmet — mediocre food at several times a good restaurant's price, and the water views are better from a public ferry or a simple daytime cruise anyway.
Photo-menu restaurants with street touts
Around Sultanahmet and off Istiklal, any restaurant whose staff pull you in off the street and whose menu is photos-first is charging two to three times the going rate for reheated versions of the same dishes. Eat where the menu is in lira and the room has locals in it.
