Istanbul Itinerary: A 5-Day Sample Plan and How to Build Your Trip

Quick answer: Five days moving from the Sultanahmet historic core and its palaces and bazaars, out onto the Bosphorus and up into Beyoğlu, across to the local Asian side at Kadıköy, and finishing on Istanbul’s Byzantine fringes and the Princes’ Islands.

Day 1 — Sultanahmet Core

Anchor day one in Sultanahmet, the old peninsula where Byzantium and the Ottomans overlap. Start early at Hagia Sophia — now a working mosque, so foreigners buy an upper-gallery ticket (about €25, roughly 900 TRY) at the northeast entrance and it closes to visitors during the five daily prayers, longest around Friday noon. Cross the square to the Blue Mosque (Sultanahmet Camii), which is free; both require covered shoulders and knees, and women a headscarf — scarves are lent at the door. Dip underground into the atmospheric Basilica Cistern (about 1,900–2,000 TRY / ~$50; Turkish inflation shifts prices, so confirm on arrival). Buy an İstanbulkart (~165 TRY for the card) and ride tram T1 everywhere. Insider tip: grab a warm sesame simit from a red cart for pocket change before the queues build.

Day 2 — Palaces & Bazaars

Devote the morning to Topkapı Palace, the Ottoman sultans’ court above the Golden Horn; entry runs about 3,000 TRY (~$75) and the Harem is a worthwhile add-on, so budget two to three hours for the courtyards, treasury and terrace views. A state Museum Pass covers Topkapı and the nearby Archaeology Museums but not Hagia Sophia or the Cistern, so do the maths for your route. Afternoon belongs to the labyrinthine Grand Bazaar (Kapalıçarşı) — over 4,000 shops, closed Sundays; browse ceramics and lamps and haggle without pressure. Walk downhill to the fragrant Spice Bazaar near Eminönü for Turkish delight and saffron. Etiquette: vendors expect friendly bargaining, roughly 30–40% off first asks. Insider tip: pause for a proper Turkish breakfast (kahvaltı) — olives, cheeses, eggs, jams and endless tea — it fuels the whole day.

Day 3 — Bosphorus & Beyoğlu

Trade monuments for the water. From Eminönü, board a Bosphorus cruise — the public ferry up the strait is cheap (a full circle tour costs roughly a few hundred TRY), passing waterfront yalı mansions, Dolmabahçe Palace and the fortress at Rumeli Hisarı. Back on shore, base the afternoon in Karaköy and climb to the medieval Galata Tower (ticketed, roughly 1,000–1,300 TRY / ~$30) for a 360-degree panorama. Stroll up through Beyoğlu along pedestrian İstiklal Caddesi, riding the nostalgic red tram to Taksim Square, then losing yourself in the side lanes of coffeehouses and meyhanes. Use tram T1 to Kabataş, then the funicular up. Insider tip: eat a balık ekmek — a grilled-mackerel sandwich from the bobbing boats at Eminönü — standing at the rail as ferries churn past.

Day 4 — Asian Side

Cross the Bosphorus to the Asian shore, where locals actually live. Take the ferry from Eminönü or Karaköy to Kadıköy (about 55–60 TRY with İstanbulkart, ~20 minutes) and dive into its produce-and-fish market, a maze of delis, spice shops and buzzing cafés far from the tour crowds. Wander the mural-splashed Yeldeğirmeni district, then walk or hop a bus up the coast to Üsküdar, more conservative and mosque-studded, for the offshore Maiden’s Tower (Kız Kulesi) view. Time it so you catch the sunset ferry back with the old-city skyline glowing behind you. Etiquette: this is a neighbourhood day, so dress relaxed but modest near mosques. Insider tip: Kadıköy is the city’s dessert capital — seek out a pistachio baklava or a scoop of stretchy Maraş dondurma from a long-established shop rather than a tourist stall.

Day 5 — Byzantine Fringe

Spend your last day on Istanbul’s quieter Byzantine edges. Ride out to the Chora (Kariye) in the Edirnekapı district to see some of the finest surviving Byzantine mosaics and frescoes anywhere; like Hagia Sophia it now functions as a mosque, so check current access and prayer-time closures and dress modestly. Trace the towering land walls of Theodosius nearby, then loop back for the elegant Süleymaniye Mosque, Sinan’s masterpiece crowning the third hill, free to enter with sweeping Golden Horn views from its terrace. If you crave green space, the ferry to the car-free Princes’ Islands (Adalar, roughly 90 minutes) offers pine woods and horse-free lanes for a half-day escape. Use buses and tram T1; keep some İstanbulkart balance topped up. Insider tip: end with a strong Turkish coffee and a slow sunset over the domes — the city’s oldest ritual.
