Start exploring Istanbul's rich history by visiting Sultanahmet Square, which is the heart of the old city. Surrounding the square are important landmarks like Blue Mosque, Hagia Sophia, and Topkapi Palace where you can immerse yourself in the Ottoman and Byzantine culture. Take a stroll to the nearby Grand Bazaar for a unique shopping experience.
Take a tour of Bosphorus Strait to appreciate the beauty of the cutting-edge city skyline and its surroundings. Spend time visiting places like Dolmabahce Palace and Maiden's Tower. Stop at Ortakoy to get a taste of its famous street food while enjoying the seaside view. End the day with a leisurely stroll at the Bebek shoreline.
Take a day trip to some of the most popular areas located in the northern part of Istanbul. Visit the Belgrad Forest and enjoy a cookout on the shores of Sazlidere Dam Lake. Head over to the Vadi Istanbul Mall for a shopping opportunity before visiting the Istinye Park Mall where you can also enjoy a movie at its cinema complex at the end of the day.
Escape the hustle and bustle of Istanbul's city centre by taking a short ferry ride to the Princes' Islands. Bike around the islands or hop on a horse-drawn carriage and marvel at the Victorian-era mansions and serene beaches. Enjoy fresh seafood and Turkish delicacies at one of the island's seafront restaurants.
Visit the modern part of Istanbul by exploring the districts of Beyoglu and Taksim. Take time to visit the trendy shops and cafes at the pedestrian street of Istiklal and watch the vintage streetcars pass by. Refuel at Asmali Mescit Quarters for Turkish street food. Head to Taksim Square for a panoramic view of the city and to experience the lively nightlife of Istanbul.
Relax and rejuvenate with an authentic Turkish bath at Cagaloglu Hamami. The centuries-old tradition of the Turkish bath is an essential experience of an Istanbul itinerary. Visit the local markets like the Spice Market and Arasta Bazaar to grab local handmade souvenirs and spices that Turkish cuisine is known for.
If you have more time, take a day trip to the epic Troya National Park to see the ancient structures and Roman ruins. If you have less time, consider removing Northern Istanbul exploration and the Turkish bath activity from the itinerary. These two are great add-ons but not essential. Try to visit indoor attractions in the late afternoon to avoid crowds. Eat like locals - street foods, kumpir (baked potatoes), pide (Turkish pizza), and baklava (sweet pastry) are must-try delicacies.
