Istanbul Travel Guide: Things to Do & Best Time to Visit

Top things to do in Istanbul

Istanbul’s historic peninsula holds many of its greatest monuments, while the Bosphorus and the districts beyond show a different side of the city.

• Hagia Sophia — Built in the 6th century as a Byzantine church and later a mosque and a museum, it is now a working mosque that visitors can see outside prayer times.
• Blue Mosque (Sultan Ahmed Mosque) — A magnificent 17th-century mosque with six minarets and an interior decorated with thousands of blue İznik tiles.
• Topkapı Palace — The former residence of the Ottoman sultans, with courtyards, the Harem, treasury and views over the Bosphorus.
• Grand Bazaar — One of the world’s oldest and largest covered markets, a maze of streets selling carpets, ceramics, jewellery and spices.
• Basilica Cistern — A vast underground Byzantine water reservoir supported by hundreds of columns, including two famous Medusa heads.
• Bosphorus cruise — A boat trip along the strait passes palaces, fortresses, waterfront mansions and the bridges linking Europe and Asia.
• Galata Tower and Karaköy — A medieval stone tower with panoramic views, above a lively district of cafés, galleries and waterfront restaurants.

Best time to visit Istanbul

Spring (April to May) and autumn (September to November) are the best times to visit, with mild temperatures that are ideal for walking between monuments and taking ferries on the Bosphorus. In April, the city’s parks and gardens are filled with tulips during the annual tulip festival.

Summer (June to August) is hot and often humid, and the main sights are at their busiest, although sea breezes and evening ferry rides make it more comfortable. Winter is cool, wet and occasionally snowy, but it is a quieter time to explore the museums, mosques and bazaars, and accommodation is easier to find.

During the holy month of Ramadan, which moves earlier each year according to the Islamic calendar, the city has a special atmosphere, with festive evening meals and illuminated mosques. Most sights and restaurants remain open, though some hours may change. The public holidays that follow Ramadan and the Feast of the Sacrifice can be very busy, as many people travel.

Getting from the airport

Istanbul Airport is the city’s main international airport, located on the European side roughly 40 km northwest of Taksim and further from the historic Sultanahmet area. It is very large, so allow plenty of time for arrival formalities and walking through the terminal.

• Metro — The airport metro line runs to Gayrettepe in the business district in around 35–40 minutes, where you can change to the M2 line for Taksim and other central areas.
• Airport buses — Dedicated shuttle buses link the airport with major hubs such as Taksim, Sultanahmet, Beşiktaş and Kadıköy. Journeys usually take around 60–90 minutes, depending on traffic.
• Taxi — Taxis wait outside the arrivals hall. The drive to the centre typically takes 45–75 minutes, and longer at rush hour. Make sure the meter is switched on.

A rechargeable Istanbulkart transport card works on the metro, trams, buses, ferries and funiculars, making travel across the city simple. Istanbul also has a second airport on the Asian side, so double-check which one you are using.

Where to stay

Istanbul is huge, so choosing the right area can save a lot of travel time. Most visitors stay on the European side, either on the historic peninsula or across the Golden Horn around Beyoğlu, while the Asian side offers a more local experience.

• Sultanahmet — On the historic peninsula, within walking distance of Hagia Sophia, the Blue Mosque and Topkapı Palace; ideal for first-time visitors focused on sightseeing.
• Beyoğlu and Taksim — The busy heart of modern Istanbul, around İstiklal Avenue, with shops, restaurants and nightlife; good for travellers who want lively evenings.
• Karaköy and Galata — Stylish waterfront districts with cafés, galleries and easy tram and ferry links; suits couples and design lovers.
• Beşiktaş and Nişantaşı — Upscale areas near the Bosphorus with elegant shopping and dining; great for a more residential feel.
• Kadıköy — On the Asian side, with a famous food market, relaxed cafés and a young, local atmosphere, linked to the European side by ferry.

Travel tips

• Mosque etiquette — Dress modestly, covering shoulders and knees; women should cover their hair with a scarf. Remove your shoes before entering and avoid visiting during prayer times, especially Friday midday prayers.
• Getting around — Use an Istanbulkart for trams, metro, buses and ferries. Ferries are a scenic and practical way to cross between Europe and Asia.
• Bargaining — Haggling is normal in the Grand Bazaar and other markets, but fixed prices apply in most shops and restaurants. Stay friendly and take your time.
• Tipping and payment — Leaving around 5–10% in restaurants is customary, and rounding up taxi fares is common. Cards are widely accepted, but carry some lira in cash for small purchases.
• Safety — Istanbul is generally safe for visitors, but watch your belongings in crowded areas and be cautious of overly friendly strangers inviting you to bars or shops.
• Entry requirements — Check passport, visa and entry rules for your nationality with official sources before you travel, as requirements can change.
