Top things to do in Istanbul
Tap any experience for photos, a little history, and practical tips.
Marvel at the Hagia Sophia
One of the world's great buildings, a vast domed monument that has been a Byzantine cathedral, an Ottoman mosque, a museum, and now a working mosque again.
- History
- Built by the emperor Justinian in 537, Hagia Sophia was the largest cathedral in the world for nearly a thousand years. After the 1453 Ottoman conquest it became a mosque, then a museum in 1935, and was reconverted to a mosque in 2020.
- Insider tip
- Go early or late to avoid the worst crowds, dress modestly (women should cover their hair), and look up at the dome, mosaics, and giant calligraphy roundels. As a mosque, it closes to tourists during prayer times.
- Good to know
- A small entry fee now applies for the upper gallery, with the main floor free as a mosque. In Sultanahmet, on the tram line.
Visit the Blue Mosque
The majestic 17th-century Sultan Ahmed Mosque facing the Hagia Sophia, famous for its cascade of domes, six minarets, and the blue İznik tiles that give it its name.
- History
- Built between 1609 and 1616 for Sultan Ahmed I, the mosque was designed to rival the Hagia Sophia across the square. Its interior is lined with more than 20,000 hand-painted blue tiles.
- Insider tip
- Enter through the tourist door, dress modestly with shoulders, knees, and (for women) hair covered, and visit outside the five daily prayer times. The exterior is stunning at night when floodlit.
- Good to know
- Free to enter as a working mosque; respect prayer times. On Sultanahmet Square, opposite the Hagia Sophia.
Tour Topkapi Palace
The opulent palace of the Ottoman sultans for nearly 400 years, a complex of courtyards, treasuries, and the harem overlooking the Bosphorus and Golden Horn.
- History
- Built by Mehmed the Conqueror from 1459, Topkapi was the seat of Ottoman power until the 1850s. Its treasury holds dazzling jewels and sacred relics, while the harem housed the sultan's family and court.
- Insider tip
- Buy a combined ticket that includes the Harem, the palace's most atmospheric section. Start early, and don't miss the Imperial Treasury and the terrace views over the water.
- Good to know
- Entry is around 1,500 TL, with the Harem extra, so book online. In Sultanahmet behind the Hagia Sophia. Closed Tuesdays.
Get lost in the Grand Bazaar
One of the world's oldest and largest covered markets, a labyrinth of over 4,000 shops selling carpets, lamps, jewelry, spices, and ceramics under painted vaults.
- History
- The Grand Bazaar (Kapalıçarşı) grew from the 1450s into a roofed city of trade with its own streets, mosques, and fountains. It has been the commercial heart of Istanbul for over 500 years.
- Insider tip
- Embrace getting lost, and always haggle, starting well below the asking price and walking away if needed. Step into a quiet han (courtyard) for tea, and compare a few stalls before buying carpets or lamps.
- Good to know
- Free to enter, open Monday to Saturday and closed Sundays. On the tram line near Beyazıt, with the spice market a short walk downhill.
Cruise the Bosphorus
A scenic ferry ride along the strait that splits the city between Europe and Asia, gliding past palaces, wooden mansions, fortresses, and waterfront neighborhoods.
- History
- The Bosphorus has been one of the world's most strategic waterways for millennia, linking the Black Sea to the Mediterranean and dividing two continents. Its shores are lined with Ottoman palaces and historic villages.
- Insider tip
- Take an inexpensive public ferry rather than a pricey tour, sit on the deck with a glass of tea, and ride between the European and Asian sides. Sunset cruises are especially beautiful as the skyline lights up.
- Good to know
- Public ferries cost just a couple of lira with an Istanbulkart, while longer Bosphorus tours run from Eminönü. Allow a half-day for the full-length cruise.
Descend into the Basilica Cistern
An atmospheric underground Byzantine reservoir, a forest of 336 columns rising from softly lit water, including two famous upside-down Medusa heads.
- History
- Built by Justinian in 532 to store water for the Great Palace, the cavernous cistern could hold around 80,000 cubic metres. The Medusa-head column bases were reused from older Roman structures.
- Insider tip
- It is cool and dim, a perfect escape from the midday heat or crowds. Go for the eerie atmosphere, the carp gliding through the water, and the Medusa heads in the far corner.
- Good to know
- Entry is around 700 TL, with timed tickets in peak season. Steps from the Hagia Sophia in Sultanahmet.
Browse the Spice Bazaar
A fragrant, colorful market near the waterfront piled high with spices, Turkish delight, dried fruit, teas, and sweets under historic vaulted arcades.
- History
- Also called the Egyptian Bazaar, it was built in the 1660s as part of the New Mosque complex and funded by taxes on goods from Cairo. It has been Istanbul's spice and food market ever since.
- Insider tip
- Taste before you buy, sample the Turkish delight and dried fruit, and explore the lively streets around it for cheaper local shopping. It is smaller and easier than the Grand Bazaar.
- Good to know
- Free to enter, open daily. By the Eminönü waterfront and the Galata Bridge, on the tram line.
Climb the Galata Tower
A medieval stone tower across the Golden Horn whose viewing balcony delivers a sweeping 360-degree panorama over the old city, the Bosphorus, and the domes and minarets below.
- History
- Built by the Genoese in 1348 as part of their fortified colony, the cone-topped tower has served as a watchtower and lookout for centuries and remains one of Istanbul's most recognizable landmarks.
- Insider tip
- Go up near sunset for golden light over Sultanahmet and the water, then explore the trendy Galata and Karaköy streets, cafes, and the lively İstiklal Avenue nearby.
- Good to know
- Entry is around 650 TL, with a queue and timed entry at peak times. In the Galata district, a walk up from the Galata Bridge or metro at Şişhane.
Know before you go
Turkish is the official language. English is spoken in tourist areas, hotels, and bazaars, though less so off the beaten track, and a few Turkish words like 'teşekkürler' (thank you) go a long way.
The Turkish lira (TL). Istanbul is good value for many visitors, though prices shift with the lira, so carry small notes for markets and tips.
Cards are widely accepted, but keep cash for bazaars, taxis, and street food. Tipping around 10% is customary in restaurants, and haggling is expected in the bazaars.
Get an Istanbulkart to ride the trams, metro, buses, and ferries cheaply. The historic Sultanahmet sights are walkable, and a Bosphorus ferry is a scenic way between the European and Asian sides.
Type C and F plugs, 230V / 50Hz, the standard European two-pin. UK and US visitors need an adapter.
Istanbul is generally safe for tourists, with the main issues being pickpocketing in crowds, taxi overcharging, and persistent touts and restaurant scams. Stay aware and agree prices upfront.
