Why Visit Istanbul?
Istanbul, the only city spanning two continents, captivates with its unique position where Europe meets Asia across the glittering Bosphorus Strait—a geographical and cultural bridge that has defined empires for millennia. This former capital of three successive empires (Roman, Byzantine, and Ottoman) layers 2,600 years of history into a vibrant modern metropolis of over 15 million where minarets pierce skylines beside contemporary art galleries, ancient hamams neighbor rooftop cocktail bars, and call to prayer echoes alongside jazz clubs. The Hagia Sophia's massive 56-meter dome, completed in 537 AD, has witnessed 1,500 years of transformation from Orthodox cathedral to imperial mosque to museum and back to mosque in 2020, its Byzantine mosaics and Islamic calligraphy coexisting in visible layers of history.
The Blue Mosque across Sultanahmet Square counters with six minarets and 20,000 hand-painted blue Iznik tiles creating a serene sanctuary where light illuminates stained-glass windows. Topkapi Palace, the Ottoman sultans' residence for nearly 400 years, reveals an opulent world through jewel-encrusted treasures, the 86-carat Spoonmaker's Diamond, sacred relics, and harem quarters overlooking the Golden Horn. Yet Istanbul's soul thrives in its bazaars—the Grand Bazaar's 4,000 shops across 61 covered streets overflow with hand-knotted carpets, ceramics, and spices from centuries of Silk Road trade.
The Egyptian Bazaar perfumes the air with saffron, dried fruits, pistachios, and Turkish delight, while Eminönü waterfront buzzes with fishermen grilling mackerel sandwiches on boats. Cruise the Bosphorus on public ferries past waterfront Ottoman yalı mansions, under suspension bridges connecting continents, past Rumeli Fortress's medieval towers, toward the Black Sea where Europe and Asia's shores fade into mist. Climb Galata Tower, a 14th-century Genoese stone tower, for 360-degree panoramas where Golden Horn, Sea of Marmara, and Bosphorus converge, then descend into Karaköy's streets for third-wave coffee, vinyl shops, and street art.
The food scene spans humble simit bread vendors to elevated meyhane taverns in Beyoğlu serving 30+ meze dishes, grilled sea bass, and rakı—the anise spirit fueling long Turkish nights. İstiklal Avenue's 1.4-kilometer pedestrian street pulses with trams, street musicians, and bookshops, while side streets hide historic churches and authentic lokanta restaurants. Hip Karaköy offers galleries and rooftop bars overlooking Bosphorus sunsets, while Kadıköy on the Asian side provides authentic neighborhood life—markets, meze bars, and ferry docks where locals commute between continents as casually as taking a bus.
Sultanahmet preserves Byzantine grandeur in the Basilica Cistern's subterranean columns and the Hippodrome's ancient obelisk. Turkish baths continue centuries-old hamam rituals. Day trips reach Princes' Islands for car-free escapes with bike rentals, electric minibuses, and pine forest walks.
With moderate climate (April-June and September-November offer perfect 15-25°C / 59-77°F weather), affordable prices, warm hospitality, and endless cultural treasures spanning empires, Istanbul delivers epic history, East-meets-West culture, Ottoman cuisine, and unforgettable experiences in its hilly, chaotic, beautiful streets.
What to Do
Historic Istanbul
Hagia Sophia
Converted back to a mosque in 2020. Since 2024–25, foreign visitors now pay a ticket (around $29 / ₺1,291) to access the upper-gallery visitor route, while the ground-floor prayer hall is free only for worshippers. The upper galleries—the main visitor area—offer close-up views of the Byzantine mosaics. Dress modestly (headscarves for women, no shorts), remove shoes at the entrance, and avoid visiting during the five daily prayer times, especially Friday noon. Go at opening (around 09:00) or late afternoon; lines swell at midday.
Blue Mosque (Sultan Ahmed)
Still an active mosque with free entry for tourists between prayers, roughly 09:00–18:00 daily. The mosque closes to visitors during each of the five daily prayers—practical visiting windows are often around 08:30–11:30, 13:00–14:30, and 15:30–16:45, but exact times shift with the sun. Dress modestly with covered shoulders and legs, remove shoes, and women should cover hair (scarves provided at entrance). The blue Iznik tiles give the mosque its name and the interior feels more intimate than Hagia Sophia's current setup. Always avoid Friday noon prayers.
Topkapi Palace
The Ottoman sultans' sprawling palace complex with courtyards, treasures and harem quarters. For foreign visitors in 2025, combined tickets (palace + harem + Hagia Irene) run around $47–$82 / ₺2,066–₺3,616 depending on current pricing and exact combo; prices have risen significantly from older estimates. Book online for a timed slot and be at the gate for the 09:00 opening—by 11:00 tour groups dominate. The Harem is worth the extra fee for its ornate tilework and private apartments. The Treasury displays jewel-encrusted daggers and enormous diamonds. Allow 3–4 hours minimum. Closed Tuesdays.
Basilica Cistern
An ancient underground water reservoir with atmospheric lighting and two famous Medusa-head column bases. Day tickets for foreign visitors are around $31 / ₺1,343 (higher rate 09:00–18:30), with evening visits priced around $47 / ₺2,066 (19:30–22:00). Book a timed entry slot online to avoid long walk-up queues. The visit only takes about 30 minutes, but the vaulted, dimly lit space is memorably cinematic. It gets humid down there. The cistern is a 5-minute walk from Hagia Sophia, so combine them in one outing.
Markets & Bosphorus
Grand Bazaar
One of the world's oldest covered markets—around 4,000 shops in labyrinthine lanes. Expect aggressive haggling (offer 40–60% of asking as an opening). Gold, carpets, ceramics, spices and endless souvenirs. It gets overwhelming fast. Go early (opens around 09:00) or late afternoon for a slightly calmer atmosphere. Closed Sundays and major religious holidays. Keep valuables secure—pickpockets are active.
Spice Bazaar & Eminönü
The Egyptian Bazaar (Spice Bazaar) is open roughly 09:00–19:00/19:30 daily, including Sundays—less aggressive than the Grand Bazaar and more fragrant, with saffron, Turkish delight, dried fruits and teas. The waterfront at Eminönü has ferries, seagulls and the famous fish-sandwich boats (balık ekmek, from around $3.53 / ₺155 and up depending on the stall). It's more authentic feeling than the Grand Bazaar. Walk across the nearby Galata Bridge for classic views and head into Beyoğlu.
Bosphorus Cruise
Public ferries with Istanbulkart (around $0.82 / ₺36 per ride) are far cheaper and often nicer than private tourist boats (which can cost 10× more or higher). The long Bosphorus public lines like Eminönü–Anadolu Kavağı offer scenic rides (~1h40–1h50 each way) for a fraction of tourist-boat prices. Sunset crossings are especially atmospheric. Short hops like Eminönü–Üsküdar cost even less. See Ottoman mansions, fortresses, and literally cross between Europe and Asia. Bring snacks—ferry food is limited.
Modern Istanbul
Galata Tower & Beyoğlu
Medieval tower with 360° views ($35 / ₺1,550, long lines—book online). Taksim Square and İstiklal Avenue offer shopping, cafes, and street life. Galata/Karaköy neighborhood has hipster cafes and street art. Nightlife centers here—bars stay open late. Walk down to Karaköy for waterfront restaurants.
Kadıköy (Asian Side)
The Asian side of Istanbul is where you'll find far fewer tourists than in Sultanahmet. Take a ferry from Eminönü (around $1.18 / ₺52 with Istanbulkart, about 20 minutes). Moda neighborhood has cafés, vintage shops, and a seaside promenade. Tuesday and Saturday markets feel very local. Try street snacks like midye dolma (stuffed mussels, from around $0.12+ / ₺5.17+ each) and fresh simit (sesame bread). It's a great counterpoint to the historic peninsula.
Turkish Hammam Experience
Traditional bathhouse ritual—expect roughly $59–$353+ / ₺2,583–₺15,495+ per person depending on how fancy the hamam is and what package you choose. Historic options like Çemberlitaş Hamamı range from $61 / ₺2,686 for entry to $173 / ₺7,593 for full packages, while Ayasofya Hürrem Sultan Hamamı starts at $130 / ₺5,682 and goes much higher for luxe experiences. Bring a swimsuit or go traditional (towels provided). The scrub massage (kese) is vigorous and thorough. Allow 1.5–2 hours. Book ahead for popular times and always confirm the full price before starting.

Practical Information
Getting There
Istanbul Airport (IST) is the main hub, 40km northwest. Havaist airport bus to Taksim is around $5.89–$7.07 / ₺258–₺310 and takes 60-90 minutes depending on traffic. Metro available. Taxis $29–$41 / ₺1,291–₺1,808 to center. Sabiha Gökçen (SAW) on Asian side serves budget airlines—Havabus from SAW to Taksim is around $8.25–$9.42 / ₺362–₺413, 90 min. High-speed trains connect Ankara (4h). Ferries connect Aegean coast ports (Çeşme, Kuşadası, Bodrum) to nearby Greek islands in summer, but no direct ferries to Istanbul from Greece.
Getting Around
Istanbul's public transport is excellent and cheap: Metro, trams, buses, and ferries use Istanbulkart (card costs about $3.86 / ₺169; standard rides are around $0.82 / ₺36, with transfer discounts). Taxis are metered. Uber and BiTaksi apps reliable. Dolmuş minibuses serve neighborhoods. Walking is rewarding but hilly. Bosphorus ferries are transport + sightseeing. Touristic Istanbulkart day passes (1/3/5/7/15 days with ride limits) are available.
Money & Payments
Turkish Lira (TRY, ₺). Exchange rate: $1 ≈ ₺44 (very volatile). Cards widely accepted, but carry cash for markets, street food, and small shops. ATMs everywhere—use bank ATMs, not standalone machines. Bargaining expected in bazaars. Tipping: round up in taxis, 10% in restaurants, $0.47–$1.18 / ₺21–₺52 for porters.
Language
Turkish is official. English spoken in hotels, tourist restaurants, and major attractions, but limited in neighborhoods and by older generations. Learning basics (Merhaba = hello, Teşekkür ederim = thank you, Lütfen = please) is appreciated. Younger Istanbulites speak decent English. Signs increasingly have English in tourist areas.
Cultural Tips
Remove shoes when entering mosques. Dress modestly for religious sites—women should cover hair, shoulders, knees (scarves provided). Ramadan affects restaurant hours and alcohol availability. Tea (çay) is social currency—accept offers. Bargain politely in bazaars (start at 50% asking price). Turkish hospitality is genuine. Lunch 12:00–15:00, dinner starts 19:00 but restaurants open all day. Book hammam experiences ahead.
