About GrandBoatline
Discover Istanbul from the water — unforgettable Bosphorus cruises crafted with passion, safety, and a deep love for this magnificent city.
Our Story
GrandBoatline was born from a simple idea: everyone deserves to experience the breathtaking beauty of the Bosphorus — the legendary strait where Europe meets Asia. Operated by BEZAK TURİZM İNŞAAT NAKLİYAT LİMİTED ŞİRKETİ, we have been welcoming guests from around the world to explore Istanbul's stunning coastline, historic landmarks, and vibrant culture from the best vantage point: the water.
From our home port in the heart of the historic peninsula, we set sail daily to show you the palaces, fortresses, mosques, and modern skyline that make Istanbul one of the world's most captivating cities.
