Strait Of Bonifacio

July 2023

Swim across the Bonifacio channel in this 16K lifetime achievement crossing from Sardinia (Italy) to the French coast of the island of Corsica! You’ll start on the beach of Rena Bianca, Sardinia (Italy) and cross to the beach of Punta Sperone, Corsica (France) across a stretch of blue Mediterranean Sea linking the two. We have helped the first American, Mexican, and Brazilian make this crossing, as well as the world record holder. Join the ranks!

16K from Italy to France

Your crossing will be overseen by Italian captain Tommaso Munatoni. In order to consider booking the swim crossing the Bocche di Bonifacio, please plan accordingly to allow 5 days, during which you will stay in the beautiful town of Santa Teresa di Gallura on Sardinia. Be aware weather and sea conditions may vary suddenly, requiring adjustment of the date of the swim. While there, practice swims are encouraged and we will provide you with training guidance and places to swim.

You must be at least 14 years of age to swim the Strait of Messina or the Bonifacio Channel. In addition, you must have an Echocardiogram (EKG) and Stress test performed by a doctor, valid within one year of your swim date. Without meeting either of these requirements, you will not be able to swim.

We highly recommend travel insurance – and not just for your stuff! Swimming in the open water can be dangerous. While we haven’t encountered any, there are jellyfish and you want to be covered in case the unexpected happens. We are not responsible for any swim or open-water related injures.
