The Bosphorus and the nature of Istanbul

One of the most common views you will see while researching Istanbul is the Bosphorus, its bridges, and the ship trips organized along it. The Bosphorus Strait of Istanbul is 32 km wide and has protected the natural beauties it has harbored for centuries with its indented and protruding structure. Its fertile shores have been home to different states and nations for centuries, and various countries have often used the Bosphorus as a route to cross toward other lands. For this reason, we think it is one of the right places to begin discovering Istanbul.
There are many islands close to Istanbul, and in summer especially, you can make island trips by crossing the Bosphorus. These islands include Heybeliada, Buyukada, and Kınalıada, and they have become some of the most attractive spots in the city for many tourists. In addition to connecting several places, the Bosphorus is also a center of attention because of the natural beauty and historical buildings around it. If you want to explore the city from the water, a Bosphorus Cruise is one of the best choices you can make.
The formation of the Bosphorus dates back many centuries and is described as a natural formation that arose as a result of a fault depression. Its relatively narrow and sinuous geographical structure is also noteworthy. Both sides of the Bosphorus are full of bays worth seeing while discovering Istanbul. A peaceful tour here, away from the crowds, offers a memorable way to understand both the city’s historical and natural features. If you would like to continue your trip across the water, you can also consider visiting the Princes' Islands.

After a spacious walk through Polonezkoy Nature Park, you can also go down to the village and enjoy a cup of tea. It is worth noting that comfortable clothing is important for hiking, because there are quite long trails in the park.

After your nature tour, you may continue the day with breakfast at restaurants near the area and enjoy pleasant family time.
