Sultanahmet Square is the heart of the Old City and surrounded by historical sites like the Blue Mosque, Hagia Sophia, and Topkapi Palace. Spend the morning strolling around the square and taking in the beautiful architecture before visiting the Topkapi Palace in the afternoon. The palace was the residence of the Ottoman Sultans for over 400 years and is now a museum featuring artifacts from Turkey's imperial past.
A Bosphorus Strait Cruise is a unique experience that offers a beautiful view of Istanbul from the water. Afterwards, head to the Grand Bazaar, one of the largest covered markets in the world, where you'll find everything from textiles and pottery to spices and souvenirs.
Dolmabahce Palace is a stunning 19th century residence that served as the administrative center of the Ottoman Empire. After touring the palace, take a stroll down Istiklal Street, which is lined with shops, cafes, and restaurants. Make sure to stop by the iconic Galata Tower for a panoramic view of the city.
The Spice Bazaar is a must-visit for foodies and those who love a good bargain. Stock up on spices, teas, and snacks before crossing the Galata Bridge to Beyoglu. Here you'll find a mixture of old and new, with trendy cafes and boutiques sharing space with historic buildings and museums.
Escape the hustle and bustle of Istanbul for a day by taking a ferry to the Princes' Islands. The islands are a car-free zone and offer a peaceful retreat with beautiful beaches and pine forests. In the evening, head to Hamdi Restaurant for a delicious plate of kebab and a stunning view of the Golden Horn.
If you have more time, consider visiting the Chora Church, the Basilica Cistern, or the Istanbul Modern Museum. If you have less time, skip the Grand Bazaar and spend more time exploring Beyoglu. Also, keep in mind that the best time to visit Istanbul is in the spring or fall when the weather is mild and the crowds are smaller.
