Tour Highlights

  • Take part in the world-famous Bosphorus Cross-Continental Swim at the heart of Istanbul

  • Swim from Asia to Europe as one of the world's busiest shipping lanes closes for this once-a-year event

  • Join open water swimmers from around the world and soak up lively Bosphorus race village

  • Discover the history and culture of the fascinating city of Istanbul

The iconic Bosphorus Cross-Continental Swim is back, bigger and better than ever. Complete an unforgettable crossing from Asia to Europe as the Bosphorus Strait in Istanbul comes to a standstill for this annual event. Join more than 2,400 competitors from across the globe as swimmers take over the Bosphorus waters and one of the busiest shipping lanes in the world is temporarily closed to traffic.

Who Is This Trip For?

The Bosphorus Cross-Continental Swim is a significant open water swim and conditions during the race may be challenging. A good experience of swimming in all sea conditions is essential and you should have relevant open water knowledge to be confident if such conditions do arise. Please be aware that this race also involves a mass start, but due to the large number of participants, it is possible to take your time and wait for a quieter period to enter the water.

This trip is only available to be booked through SwimTrek as a complete package (including accommodation). If you choose not to join as a swimmer, there is the opportunity to join as a supporter. There are a limited number of supporters tickets available which include shared accommodation with a race participant and all SwimTrek transfers.

NOTE: Turkish passport holders are unable to register for this event through SwimTrek and must apply via the Turkish Olympic Committee directly.

Location Summary


Istanbul is a city of contrasts with an enchanting blend of Eastern and Western culture giving this vibrant and modern city a truly unique identity.

As Byzantium, Constantinople and finally, Istanbul, it has been the capital of three empires, each leaving their mark in the form of stunning palaces, castles, mosques, churches and monuments. Set in a beautiful location surrounded by the waters of the narrow strait of the Bosphorus and the serene sea of Marmara, Istanbul is uniquely European and authentically Asian at the same time.


The Bosphorus is a 30 km strait which divides Istanbul and joins the Sea of Marmara with the Black Sea. The width of the strait varies from 500 m - 3 km and its depth from 50 - 120 m. As one of the busiest waterways in the world, the Bosphorus sees hundreds of passenger and commercial vessels travel across and along it every day.

The name Bosphorus comes from Greek legend: Zeus had an affair with a beautiful woman named lo. When Hera, his wife, discovered his infidelity, she turned Io into a cow and created a horsefly to sting her. Io jumped clear across the strait. Thus, ‘bous’ (cow) + ‘poros’ (crossing-place) = Bosphorus (Crossing place of the cow).

Special Booking Terms

A 40% deposit is required for this event. We can only guarantee your place upon successful registration with the organising body. The required documents will be emailed to you when you have secured a place in the swim. The deposit payment will be refunded back to you if you are unsuccessful.

Bosphorus Ballot

Competition for places on this iconic swim is stronger than ever, so as done in previous years, a ballot system will be running to give as many people as possible a fair opportunity to secure a spot. The best way to secure one of the limited number of places in this heavily oversubscribed international event is to enter the SwimTrek Bosphorus Ballot. The Bosphorus ballot is a system whereby all swimmers who book to take part in the Bosphorus event, via SwimTrek, will be placed into a draw for a chance to be allocated one of the limited available places in the race.

Please note that entering the ballot does not guarantee your place in the Bosphorus swim.

How Does It Work?

  • To enter the ballot, make a booking on one of the available Bosphorus packages for all guests that would like to take part in the swim event.

  • Once you’ve made your booking, you must complete the required profile information in your SwimTrek account within 48 hours. Without this information, we will be unable to enter you into the ballot and your booking may be cancelled. To complete the required profile information, log in to your SwimTrek account and fill out the ‘Personal Details, ‘Travel Details’ and ‘Health Details’ and ‘My Contact Details’ sections for all swimmers on your booking. Please ensure the full name matches the name on your passport. If you need help to complete the required profile information, please contact the SwimTrek office.

You’ll then need to complete the paperwork (including the swim coach sign off and your declaration from a medical practitioner) and send this back to SwimTrek within six weeks. Please read the 'Important Information' section below for more details before entering.

  • Once you return your application form to us, we’ll check to make sure that it has been completed correctly. We’ll then send you an email to confirm that we have received your application and it will be submitted for the event, so that you can begin making plans for your trip to Turkey.

Trip Grading

Bosphorus Cross-Continental Swim

The world’s most concentrated shipping lane is closed to all traffic as we participate in this annual race. You can either race to win it or just go along at your own pace. We have given this trip a ‘Moderate’ grading. Most swimmers comfortable in the open water will be able to take part and enjoy one of these trips.

Group Size and Boat Support

The Bosphorus Cross-Continental Swim is a mass start event. Boat support on this trip includes a flotilla of small boats arranged by the event organiser. Please note that this boat support is subject to change without notice and cannot be guaranteed.

Swimming Conditions

An interesting feature of the Bosphorus strait is its curious water flow. On the surface, the Bosphorus usually flows from the Black Sea towards the Sea of Marmara (carrying our Bosphorus swimmers along with it). However, at greater depths, the current flows in the opposite direction, carrying huge volumes of water back towards the Black Sea. You should note that conditions in this large body of water may become more challenging. This race involves a mass start, despite the large number of participants it is possible to take your time and wait for a quieter period to enter the water.

Swimming in the sea is a fantastic experience, however you should be aware that certain marine life such as sea lice, jellyfish and sea urchins could be present during the swim. If you suffer from anaphylaxis, please consult the office prior to booking.

As SwimTrekkers come from all over the world, and join our swimming holidays in numerous destinations, we don't currently offer flights as part of our SwimTrek packages. We do however want to do as much as we can to ensure that our guests get the best deals when travelling to one of our trips so check out SwimTrek's tips to help you get the best deals for your flights page on the website.
