19 Best things to do in Istanbul, Turkey, in 4 days

Introduction

Istanbul is Turkey’s most iconic city and also its most visited. What makes it truly unique is its position straddling two continents — Europe and Asia — split by the famous Bosphorus Strait.

Once known as Constantinople, Istanbul was the final capital of the Roman/Byzantine Empire and later a key city of the Ottoman Empire. Its long and layered history can be seen and felt everywhere — from the ancient churches turned mosques to bustling bazaars and palaces overlooking the sea.

Today, Istanbul is home to over 15.5 million people and spreads across 5,534 km². It’s a city of contrasts, where old and new collide in the most fascinating way.

In this Istanbul travel guide, we’ll share everything you need to know to plan your trip — with tips from our 4-day visit, plus Alex’s insights from when he lived here for five months.

Here are all your accommodation options in Istanbul.

How to get there

Istanbul has two main international airports: Istanbul Airport (IST) on the European side and Sabiha Gökçen Airport (SAW) on the Asian side. Both receive international flights daily from all over the world, with IST being the primary hub for long-haul and international travel.

• From Europe or North America: Direct flights arrive at IST from major cities like Paris, London, New York, and Toronto. Turkish Airlines often offers the most convenient connections.
• From Asia or the Middle East: You might land at either IST or SAW, depending on the airline. Low-cost carriers often use SAW.
• From within Turkey: Domestic flights run frequently and affordably between Istanbul and cities like Cappadocia, Izmir, Antalya, and Ankara.

Once you land:

• From Istanbul Airport (IST): Take the Havaist Airport Shuttle (around 1 hour to the city center, 90–110 TRY / approx. €3–4 / $3–4.50) or a taxi (expect to pay ~500–700 TRY / approx. €14–20 / $15–22).
• From Sabiha Gökçen (SAW): You can also use Havabus to reach Kadıköy or Taksim (90–120 minutes depending on traffic). Taxis from SAW are slightly cheaper than from IST.

Tip: Always check traffic before taking a taxi — Istanbul traffic can be intense, especially during rush hour.

Moving Around Istanbul

Istanbul is a massive city, but getting around is surprisingly manageable thanks to a solid public transport system and plenty of local options.

1. Public Transportation (best budget option)

Istanbul has metros, trams, ferries, buses, and funiculars — and they’re all connected. To use them, get an Istanbulkart, a rechargeable transport card that works on all modes. You can buy and top it up at kiosks or machines near most stations.

• Tram T1 is perfect for sightseeing: it connects Sultanahmet (Blue Mosque, Hagia Sophia) to Galata and Kabataş.
• Metro is fast for longer distances (like reaching Şişli or Levent).
• Ferries cross the Bosphorus between the European and Asian sides — a scenic must-do.
• Funiculars help with Istanbul’s many hills, especially between Karaköy and Beyoğlu.

2. Taxi or Uber

Taxis are common but often inconsistent — insist on using the meter. Uber works well in Istanbul (it mostly books regular yellow taxis). Just be prepared for traffic, especially during peak hours.

3. Walking

If you stay central (Sultanahmet, Karaköy, or Galata), many major sites are walkable. Just be ready for steep streets — Istanbul has serious hills.

4. Local Tips

• Avoid rush hour (8–10 AM and 5–7 PM) if possible — it can double travel time.
• Download Moovit or Trafi to check live transport routes and timetables.
• If crossing continents, ferries are the most peaceful and scenic way.

When to Visit

Istanbul is a year-round destination, but your experience can vary a lot depending on the season. From tulip-filled spring streets to cozy winter bazaars, here’s what to expect throughout the year:

• Spring (March to May): Spring is one of the best times to visit Istanbul. The weather is pleasant, with daytime temperatures between 15–25°C (59–77°F). The parks start blooming (especially during the Tulip Festival in April), and the crowds are still reasonable. It’s perfect for walking tours, ferry rides, and exploring the outdoor sites.
• Summer (June to August): Summer is hot and busy, with temperatures often reaching 30–35°C (86–95°F). Expect large tourist crowds and high humidity, especially in July and August. That said, summer evenings by the Bosphorus can be magical. If you visit in this season, schedule your activities early morning or late afternoon and stay hydrated.
• Autumn (September to November): Autumn is another great time to visit. The weather stays warm until mid-October, averaging around 18–28°C (64–82°F). The city feels more relaxed, and the light over the mosques and rooftops is golden — ideal for photography. It’s a great shoulder season if you want fewer crowds and mild weather.
• Winter (December to February): Winter in Istanbul is mild but damp, with temperatures ranging from 5–12°C (41–54°F). Snow is rare but possible. This is the quietest season, so you’ll enjoy lower prices and emptier attractions. Some outdoor sights are less appealing in the rain, but Istanbul’s many mosques, museums, and cafés are cozy winter refuges.

Our Tip: Visit in April or October for the best balance of weather, atmosphere, and manageable crowds. These months are ideal for walking, sightseeing, and enjoying Istanbul at its best.

Where to Stay

Istanbul is a sprawling city, but for most travelers, the choice comes down to staying near the historic old town (Sultanahmet) or in the more modern and lively areas like Galata or Karaköy. If it’s your first time in Istanbul, we recommend staying in or around Sultanahmet for easy access to the main sites. But if you’ve already done the classics or want to feel a bit more like a local, Galata or Cihangir are great spots too.

Here are a few of our top hotel picks:

• Budget: Best Point Hotel Old City – A great location within walking distance of the Blue Mosque and Hagia Sophia, with friendly staff and even a terrace with Bosphorus views.
• Mid-Range: Louis Appartements Galata – Spacious, modern flats in the heart of Galata, perfect if you’re looking for a stylish base with a local vibe. If you stay here, don’t miss the lovely breakfast at Şirin Fırın, a small neighborhood bakery just around the corner.
• Luxury: Four Seasons Hotel Istanbul at Sultanahmet – If you’re going all in, this former prison turned 5-star hotel is pure magic, especially in the garden. You’re right in the heart of old Istanbul, yet it feels like a peaceful retreat.

Here are all your accommodation options in Istanbul.

Here’s a little taste of what you shouldn’t miss:

Breakfast Favorites: Turkish breakfast is a feast in itself — you’ll find tables overflowing with small plates, and you should try as much as you can.

• Olives: yes, even at breakfast — and they’re amazing

Lunch & Dinner

• Pide: often called Turkish pizza, this boat-shaped flatbread comes with all kinds of toppings
• Lahmacun: thinner than pide, topped with minced meat and herbs — squeeze lemon, roll it up, enjoy

• Balık Ekmek: grilled fish sandwich usually sold near the Galata Bridge

• İçli Köfte: bulgur balls stuffed with spicy minced meat

Kebabs You Have to Try

Something Sweet

• Künefe: warm dessert made of shredded pastry and cheese, soaked in syrup
• Baklava: the classic — layers of filo, nuts, and syrupy goodness

To Drink

• Raki: anise-flavored spirit often called “lion’s milk”
• Salep: a hot winter drink made from orchid root and milk — thick, sweet, and comforting

There’s so much more, but even this short list should keep your taste buds happy. Honestly, eating in Istanbul is an experience of its own.

Tip: Don’t forget to bring a good camera, such as the SONY A7 — it makes all the difference for capturing those unforgettable moments.

Things to do in Istanbul

Climb the Galata Tower for a Panoramic View

One of Istanbul’s most iconic landmarks, the Galata Tower is a must-see — and even more of a must-climb. From the top, you get a stunning 360° view over the Bosphorus, the old city, and the maze of rooftops below. It’s especially beautiful at sunset, though you’ll want to come early to beat the crowds.

The tower itself is a 63-meter-tall medieval stone structure, built in 1348 by the Genoese. It once guarded the northern end of the giant sea chain that blocked enemy ships from entering the Golden Horn.

Today, you can either enjoy the view or, if you’re in the mood for something a bit more special, reserve a table at the tower’s restaurant for a romantic dinner high above the city lights.

Explore Sultanahmet Square, the Heart of Old Constantinople

Once the Hippodrome of Constantinople, this historic square was the center of social and sporting life during the Byzantine Empire. While little remains of the original structure, you can still see fragments like the Obelisk of Theodosius and the Serpent Column.

The square is now a peaceful place to walk around, framed by some of Istanbul’s most iconic landmarks — the Hagia Sophia and the Blue Mosque — making it the perfect starting point to explore the city’s rich history.

Visit the Timeless Hagia Sophia, from Church to Mosque

Today, it’s still an active mosque, blending stunning Byzantine architecture with Ottoman touches. Don’t miss its massive dome, intricate mosaics, and spiritual atmosphere that spans empires and religions.

Admire the Obelisk of Theodosius

Standing in Sultanahmet Square, this ancient Egyptian obelisk is one of the oldest monuments in Istanbul. Originally erected around 1425 BC at the Temple of Karnak in Luxor, it was later transported to Constantinople by Roman Emperor Theodosius I in the 4th century AD. Now resting on a marble pedestal richly carved with reliefs, it’s a striking symbol of the city’s layered past and a must-see when strolling through the former Hippodrome.

Visit Topkapı Palace Museum

Step into the opulent world of the Ottoman Empire at Topkapı Palace, once the main residence and ruling center of the sultans for over 400 years.

Its location also offers panoramic views of the Bosphorus, making it as beautiful as it is historic.

Stroll under the shady trees, enjoy the well-maintained gardens, and soak in views of the Bosphorus from its lower paths. Perfect for a quiet break between sightseeing.

Visit the Basilica Cistern

Step into the mysterious underground world of the Basilica Cistern, the largest of Istanbul’s ancient water reservoirs. Built in the 6th century during the reign of Emperor Justinian I, this atmospheric space is supported by 336 marble columns and used to supply water to the imperial palace. Keep an eye out for the famous Medusa heads at the base of two columns. It’s a unique and slightly eerie spot that feels far away from the city’s chaos.

Walk Down Istiklal Caddesi

Stroll along one of Istanbul’s most iconic streets. Istiklal Caddesi is a lively 1.4 km-long pedestrian avenue lined with shops, cafés, galleries, and historic buildings. The nostalgic red tram still runs along the center, adding charm to the experience. Whether you’re shopping, people-watching, or simply walking from Taksim Square to Galata, this is one of the city’s busiest and most atmospheric streets — especially in the evening.

Here are all your accommodation options in Istanbul.

Visit Sent Antuan Kilisesi

Step into the Church of St. Anthony of Padua, the largest Roman Catholic church in Istanbul.

It’s a peaceful place to pause amid the buzz of the city, with impressive architecture, stained-glass windows, and a calm courtyard.

Take a scenic ferry ride across the Bosphorus to reach the laid-back neighborhood of Moda, located on the Asian side of Istanbul. Once there, stroll through its leafy streets, local boutiques, and peaceful parks. The waterfront promenade offers wide views of the sea — and with a bit of luck, you might even spot dolphins in the distance. It’s one of the best places in town to relax with a coffee or catch the sunset with the locals.

Admire the Iconic Maiden’s Tower

Watch one of Istanbul’s most iconic landmarks rise from a tiny islet in the middle of the Bosphorus. The Maiden’s Tower has served many purposes over the centuries — from a lighthouse to a quarantine station — and is wrapped in legends. While you can visit it by boat, one of the best views is from the Üsküdar coastline at sunset, when the tower is beautifully silhouetted against the water.

Walk the European Bosphorus: From Beşiktaş to Ortaköy

Take one of the most scenic walks in Istanbul, starting from Kabataş and following the Bosphorus north through Beşiktaş to Ortaköy.

Along the way, admire the elegant silhouette of the Dolmabahçe Mosque, explore the majestic Dolmabahçe Palace, breathe in fresh air in Yıldız Park, and finish at the Büyük Mecidiye Mosque (also known as the Ortaköy Mosque), a waterfront gem framed by the Bosphorus Bridge.

The walk is full of energy, history, and stunning views.
