Istanbul Island Escape Sivriada Swimming Tour & Onboard Lunch

Dive into Crystal-Clear Open Waters Unlike the busy shores of the Bosphorus, Sivriada sits in deep, open water, offering some of the cleanest, clearest swimming conditions near the city. We drop anchor inside a protected, semi-circular ancient Roman quarry harbor. This natural stone basin blocks the open-sea currents, creating a glassy, calm, turquoise pool perfect for: Deep-water swimming straight off the deck. Snorkeling along the submerged rocky reefs to spot local Aegean marine life. Floating on paddleboards or inflatables in absolute tranquility, with nothing but the sound of seagulls and gentle waves. A Dash of Mystery and History When you aren’t in the water, you can soak in the island’s raw, haunting beauty. Sivriada is steeped in lore, home to the stone ruins of a 10th-century Byzantine monastery and ancient quarries that built the foundations of Istanbul itself.
