Bosphorus Yachts Karaköy · Private Bosphorus swimming tour from Istanbul Yes. You can. And it's one of the most extraordinary things you can do in Istanbul. Most people assume the Bosphorus is off limits for swimming, too busy, too urban, too much going on. But go far enough north and the city completely disappears. No buildings, no traffic, no noise. Just dense green hillsides, calm sheltered bays, and water that sits at the point where the Bosphorus meets the Black Sea. That's where we take you. This tour goes all the way up to the northern Bosphorus, where Istanbul's buildings run out, the scenery turns wild and green, and the strait opens into the Black Sea. It's one of the most dramatic and least known experiences available in this city. And it's private, the yacht is exclusively yours. 1. This is a full day on the water Plan for 6 to 8 hours minimum. You set off in the morning from Karaköy or Bebek and sail north as the city gradually disappears behind you. Breakfast is served on board. By the time you arrive at your swimming spot the skyline is gone and what surrounds you looks nothing like Istanbul. The crew can prepare food on board throughout the day, or we can arrange catering. You can also bring your own. You choose what the day looks like, the yacht and crew are there to make it happen. 2. Where do you swim? The Third Bridge area sits at the northern end of the Bosphorus, at the point where the strait meets the Black Sea near the Yavuz Sultan Selim Bridge, the third and newest of Istanbul's Bosphorus bridges. There are no buildings here. Dense green forest on both sides, hillsides dropping straight into the water, and a sheltered bay where the water is calm and clear. The scenery is genuinely supernatural, wild and quiet in a way that feels impossible given you are still technically inside Istanbul. This is the most remote and spectacular swimming experience we offer and the one guests talk about long after they leave. 3. What a typical day looks like You board in the morning, usually around 9 or 10am. Breakfast is served on deck as you leave the harbour and head north. Within the first hour the city already feels far away. The scenery changes as you sail further up the strait. Buildings thin out, hillsides get greener, and by the time you pass under the Yavuz Sultan Selim Bridge you feel like you have left Istanbul entirely. The crew anchors in the bay and the day begins properly. You swim, come back on deck, eat, go back in. No schedule, no rush. The afternoon is yours. The sail back south in the late afternoon is its own kind of beautiful, the light shifts, the city slowly comes back into view, and you arrive at the dock in the early evening feeling like the day was worth every hour of it. 4. Can I add extras? Yes, and most people do. This is a private charter so the day is fully customisable. The most popular add-ons are breakfast on board, full catering and mezze throughout the day, drinks packages including wine and sparkling wine, decoration setups for birthdays or special occasions, and hotel transfers to and from the departure point. If you have something specific in mind, a celebration, a particular setup, anything at all, just message us and we will put it together. 5. What to bring Swimwear, at least one spare set so you have something dry for the sail back. A towel. Fresh clothes to change into after swimming. Sunscreen and plenty of it, you will be on open water with no shade for most of the day. Sunglasses. A hat. If you tend to feel the cold on the water, a light layer for the journey back as the temperature drops in the late afternoon. Everything else the crew sorts out.
