Top 10 Things to Do in Istanbul

Istanbul is a city where every corner tells a story, and narrowing down what to do can be overwhelming for first-time visitors. This guide covers the top 10 experiences that define Istanbul — from the awe-inspiring Hagia Sophia and the magnificent Blue Mosque to the bustling Grand Bazaar and a leisurely Bosphorus cruise. We include practical information for each attraction: opening hours, entrance fees, the best time to visit to avoid crowds, and insider tips that enhance your experience. Whether you have two days or two weeks, these ten activities capture the essence of Istanbul’s history, culture, cuisine, and beauty. Each recommendation includes nearby dining suggestions and transportation advice so you can plan efficiently.

1. Hagia Sophia: A Journey Through Time

Hagia Sophia is arguably the most iconic building in Istanbul and one of the most significant architectural achievements in human history. Built in 537 AD by Byzantine Emperor Justinian I, it served as a cathedral for nearly a thousand years before becoming a mosque under the Ottomans in 1453. Today it functions as a mosque again, open to visitors outside of prayer times. Entry is free for worship purposes, but a museum-style visitor entrance on the upper gallery level provides access for tourists.

Plan to spend at least 90 minutes inside. Highlights include the massive dome rising 55 meters above the floor, the 10th-century golden mosaics depicting Christ Pantocrator and the Virgin Mary, the marble Door of the Imperial Gallery, and the four calligraphic medallions inscribed with the names of Allah, the Prophet Muhammad, and the first four caliphs. The upper gallery offers the best views and houses the famous Deesis mosaic, one of the finest examples of Byzantine art.

Visit early in the morning right after opening (9:00 AM in summer, 8:30 AM in winter) to avoid tour groups. The site closes to tourists during the five daily prayer times, so check the schedule posted at the entrance. Dress modestly — women should cover their hair, and both men and women should avoid shorts. There is no entrance fee, but donations are welcome. The nearest tram stop is Sultanahmet, directly outside.

2. The Blue Mosque and Sultanahmet Square

The Sultan Ahmed Mosque, popularly known as the Blue Mosque, stands directly across from Hagia Sophia and together they frame Sultanahmet Square — the heart of historic Istanbul. Completed in 1616 under Sultan Ahmed I, the mosque gets its nickname from the more than 20,000 hand-painted Iznik tiles that line its interior in patterns of blue, green, and turquoise flowers and geometric designs. The mosque features six minarets, a detail that caused controversy at the time of construction because only the Great Mosque in Mecca had the same number.

Entry is free and the mosque welcomes visitors outside of prayer times. Remove your shoes at the entrance and place them in the provided plastic bags. Women should cover their hair with a scarf, which is provided free of charge at the entrance. The interior is breathtaking — sunlight filters through more than 200 stained-glass windows, illuminating the tiles and the vast carpet that covers the floor in a unified pattern designed to guide worshippers toward Mecca.

After visiting the mosque, spend time in Sultanahmet Square itself. This was the site of the Hippodrome of Constantinople, the sporting and social center of the Byzantine capital. Today you can see the Egyptian Obelisk, the Serpentine Column, and the Obelisk of Theodosius, all ancient monuments that have stood here for centuries. The square is pedestrian-friendly with benches, gardens, and cafes where you can enjoy a Turkish tea while admiring both the Blue Mosque and Hagia Sophia.

3. Topkapi Palace and the Harem

Topkapi Palace was the primary residence and administrative headquarters of the Ottoman sultans for nearly 400 years, from the conquest of Constantinople in 1453 until the mid-19th century. The palace complex sits on a promontory overlooking the Golden Horn, the Bosphorus, and the Sea of Marmara, offering some of the best views in the city. Plan for two to three hours to explore the multiple courtyards, pavilions, and exhibitions.

The palace ticket includes access to the Imperial Treasury, which houses the Spoonmaker’s Diamond — an 86-carat diamond that is one of the largest in the world — along with the Topkapi Dagger and an extensive collection of Ottoman jewelry. The Pavilion of the Holy Mantle contains sacred relics of the Prophet Muhammad, including his cloak, hair, and footprint. The palace kitchens now display one of the world’s finest collections of Chinese and Japanese porcelain.

The Harem requires a separate ticket and is well worth the additional cost. This was the private living quarters of the sultan, his family, and his concubines. The Harem contains more than 400 rooms, including the beautifully tiled apartments of the Queen Mother, the Imperial Hall where the sultan entertained, and the Courtyard of the Concubines. The intricate Iznik tilework, stained glass, and gold-leaf decorations in the Harem rival anything else in Istanbul.

4. Grand Bazaar: 4,000 Shops of Wonder

The Grand Bazaar is one of the oldest and largest covered markets in the world, with over 4,000 shops spread across 61 covered streets. It has been a center of trade since 1461 and remains a working market where locals shop alongside tourists. Enter through the Nuruosmaniye Gate near Beyazit for the most dramatic entrance, with its tall archway and soaring domed ceiling.

The bazaar is organized by guild — jewelry shops in one section, leather in another, carpets and kilims in another, and spices and sweets near the entrances. Bargaining is expected, so never accept the first price. Start by offering 40-50% of the asking price and negotiate from there. Good-natured haggling is part of Turkish culture, and shopkeepers will often offer you tea while you negotiate.

Key items to look for include handmade Turkish carpets (ask for the shopkeeper to explain the difference between silk and wool knots), gold jewelry (Turkey has excellent craftsmanship at reasonable prices), leather goods, ceramic bowls and tiles from Iznik and Kutahya, and Turkish delight in dozens of flavors. Be wary of “antique” items that are actually reproductions. The bazaar is open Monday through Saturday from 8:30 AM to 7:00 PM and is closed on Sundays and religious holidays.

5. Bosphorus Cruise: Two Continents from the Water

A Bosphorus cruise is the single best way to appreciate Istanbul’s unique geography — the city straddles two continents, separated by the Bosphorus Strait that connects the Black Sea to the Sea of Marmara. The cruise takes you past Ottoman palaces, waterfront mansions (yalis), ancient fortresses, and modern bridges while you enjoy the sea breeze and the city skyline from a perspective impossible to get on land.

Several cruise options are available. The public ferry from Eminonu runs a full-length cruise to Anadolu Kavagi near the Black Sea, taking about two hours each way with a stop for lunch. This costs roughly 150 TL and is the most authentic and affordable option. Private cruise companies offer shorter 1.5 to 2-hour sightseeing cruises with commentary in multiple languages, departing from both Eminonu and Besiktas. For a special experience, book a sunset cruise that includes dinner and traditional Turkish music — the city’s skyline at golden hour from the water is unforgettable.

Highlights along the route include Dolmabahce Palace, the Ciragan Palace (now a Kempinski hotel), the Ortakoy Mosque beneath the Bosphorus Bridge, Rumeli Fortress (built by Mehmed II in 1453 in just four months), and the Fatih Sultan Mehmet Bridge. The best time for a cruise is between April and October when the weather is warm and skies are clear.

6. Spice Bazaar and Egyptian Market

The Spice Bazaar, also known as the Egyptian Bazaar (Misir Carsisi), is the second-most famous market in Istanbul and arguably the more atmospheric one. Located in the Eminonu district near the New Mosque, this 17th-century L-shaped market specializes in spices, dried fruits, nuts, teas, Turkish delight, and other food items. The air inside is thick with the aroma of saffron, sumac, cumin, cardamom, and dozens of other spices displayed in colorful mounds at each stall.

Shopping here is more relaxed than at the Grand Bazaar, with less aggressive haggling. Buy saffron (Turkey produces excellent saffron at a fraction of the price you would pay in Europe), Turkish tea in flavors like apple, pomegranate, and rose, pistachio Turkish delight (look for the fresh kind, not the pre-packaged version), dried figs and apricots, and rose water. Many stalls offer free samples, so taste before you buy.

After exploring the bazaar, step outside to the area around Eminonu. Here you will find the famous balik ekmek (fish sandwich) boats selling freshly grilled fish in bread for about 100 TL — a quintessential Istanbul street food experience. Nearby, the New Mosque (Yeni Cami) is worth a quick visit, and the Galata Bridge connecting Eminonu to Karakoy offers great views up and down the Golden Horn.

7. Galata Tower and Karakoy District

The Galata Tower is a 14th-century Genoese tower that stands 67 meters tall on a hill in the Beyoglu district. It offers 360-degree panoramic views of Istanbul — from the Old City and the Golden Horn to the Bosphorus and the Asian side. On a clear day you can see all the way to the Princes’ Islands and the hills of the Asian shore. The tower has a modern elevator that takes you to the top observation deck, where you can walk around the exterior balcony.

After visiting the tower, explore the surrounding Galata neighborhood. The cobblestone streets are filled with antique shops, art galleries, cafes, and boutique clothing stores. Walk down Galip Dede Street toward Tunel to see vintage music shops and instrument makers. The area around Serdar-i Ekrem Street is known for its independent designers and craft shops.

From Galata, it is a short walk to Karakoy, one of the most rapidly transforming neighborhoods in Istanbul. Once a gritty port area, Karakoy is now filled with trendy coffee shops, cocktail bars, and restaurants in restored historic buildings. Try the Turkish coffee at Karabatak, one of the neighborhood’s pioneering cafes, or the baklava at Karakoy Gulluoglu — considered by many to be the best baklava in Istanbul. From Karakoy, you can take the historic Tunel funicular (the second-oldest underground railway in the world, dating to 1875) up to Istiklal Street.

8. Turkish Bath (Hamam) Experience

A Turkish bath, or hamam, is a cultural institution that dates back to the Ottoman era and offers a uniquely relaxing experience that every visitor to Istanbul should try at least once. The hamam ritual involves moving through a series of rooms — from the warm camekan (entrance hall) to the hot hararet (main bathing room) and back — while being scrubbed, washed, and massaged by an attendant (tellak for men, natir for women).

The process begins in the warm entrance hall, where you receive a pestemal (a thin cotton towel) and pebbled sandals. You then move to the hot room, where you lie on the heated marble gobek tasi (belly stone) in the center and sweat for 15-20 minutes. The attendant then approaches with a kese (rough mitt) and exfoliates your entire body, removing layers of dead skin you did not know you had. This is followed by a soapy massage — the attendant creates clouds of foam from a silk bag and washes you in bubbles. The experience concludes with a rinse and a rest in the cool room with tea.

Two of the most historic hamams in Istanbul are Cagaloglu Hamami (built in 1741 and used by King Edward VIII and Franz Liszt) and Cemberlitas Hamami (built in 1584 by the architect Sinan). Both offer separate sections for men and women. Expect to pay between 1,500 and 3,500 TL depending on the services you choose. Book in advance during peak season, and allow two hours for the full experience including rest time.

9. Istiklal Street and Taksim Square

Istiklal Street (Istiklal Caddesi) is a 1.4-kilometer pedestrian avenue running from the Galata/Tunel area to Taksim Square, and it is the beating heart of modern Istanbul. The street is lined with 19th-century buildings housing international shops, local boutiques, cafes, restaurants, churches, and consulates. A historic red tram runs along the center of the street, adding charm and providing a convenient ride for tired legs.

Along Istiklal, notable stops include the Church of St. Anthony of Padua, the largest Catholic church in Istanbul; the Flower Passage (Cicek Pasaji), a historic arcade with restaurants; and the Balik Pasaji (Fish Market), where you can eat fresh oysters and seafood. The Mevlevi Lodge Museum, dedicated to the Whirling Dervishes, offers performances of the sema ceremony — a mesmerizing spiritual dance — on selected days.

Taksim Square, at the northern end of Istiklal, is the city’s main public gathering space. The Monument of the Republic, erected in 1928, stands at the center. From Taksim, you can take the funicular down to Kabatas to connect to the tram system, or walk through Gezi Park — one of the few green spaces in the area. The surrounding neighborhood of Cihangir and Beyoglu offers excellent dining, from traditional Turkish restaurants to international cuisine.

10. Princes’ Islands: A Car-Free Escape

The Princes’ Islands (Adalar) are a chain of nine islands in the Sea of Marmara, about an hour by ferry from Istanbul. Four of the islands are open to visitors, with Buyukada being the largest and most popular. The islands offer a peaceful escape from the noise and traffic of the city — no motorized vehicles are allowed except for municipal services, so transportation is by bicycle, electric cart, or horse-drawn carriage.

Buyukada is the most rewarding island to visit. Rent a bicycle and ride along the waterfront promenade, passing Victorian-era mansions and pine forests. Climb or take a phaeton (horse carriage) to the top of the island to the Aya Yorgi Church, a Greek Orthodox church with a small monastery that offers spectacular views and a simple restaurant serving grilled meat and wine. The island’s main streets are filled with ice cream shops, seafood restaurants, and Turkish tea gardens.

Ferries to the Princes’ Islands depart from Kabatas, Eminonu, and Bostanci. The journey takes 45 to 90 minutes depending on the number of stops. A round-trip ferry ticket costs about 100 TL with an Istanbulkart. Go on a weekday to avoid the weekend crowds, and bring swimwear if you want to swim at the beaches on the far side of Buyukada. The islands are beautiful year-round but are especially lovely in spring when the Judas trees bloom purple along the hillsides.

Practical Tips for Your Istanbul Visit

Getting around Istanbul is straightforward thanks to the public transit system. Buy an Istanbulkart from any tram or metro station and load it with credit — it works on trams, metros, buses, ferries, and funiculars. The T1 tram line connects most of the Old City attractions, while the M2 metro connects Taksim with the rest of the system. Taxis are plentiful but make sure the driver uses the meter.

The best times to visit Istanbul are spring (April to May) and autumn (September to November) when temperatures are mild and crowds are smaller. Summer is hot and humid with peak tourist numbers, while winter is cold and rainy but offers the advantage of shorter queues at major attractions.

Turkish cuisine is one of the world’s great cuisines and Istanbul is the best place to experience it. Do not miss kofte (meatballs) at the famous Kofteci Ali Usta, fresh fish at a Bosphorus-side restaurant, menemen (Turkish scrambled eggs with tomato and peppers) for breakfast, and of course, Turkish tea and coffee at every opportunity. For a sweet treat, try künefe — a warm cheese pastry soaked in syrup — at any cafe in Karakoy or Besiktas.
