Cortés Open Los Cabos Cortés Open Los Cabos is an open-water swimming experience that invites participants to discover the Sea of Cortez from a unique perspective—through sport, challenge, and a deep connection with the ocean. Held at Palmilla Beach in Los Cabos, Baja California Sur, the event brings together swimmers from Mexico and around the world in one of the country’s most spectacular destinations. Its 1.3K, 3K, 5K, and 7K courses offer different levels of challenge, making the competition an experience for both those taking their first steps into open-water swimming and seasoned athletes. The setting is as extraordinary as the challenge itself. Renowned for its remarkable marine biodiversity and dramatic landscapes, the Sea of Cortez was famously described by French oceanographer and explorer Jacques Cousteau as “the world’s aquarium.” Its waters, natural richness, and the beauty of the Baja California Sur peninsula transform every stroke into an opportunity to connect with one of the planet’s most fascinating marine ecosystems. Beyond the starting line and the finish, Cortés Open offers a different way to experience Los Cabos: swimming in the waters of the Sea of Cortez, enjoying an extraordinary natural setting, and becoming part of an international community united by a shared passion for the ocean and sport. Because here, it is not only about reaching the finish line—it is about deciding how much you are willing to give when the moment comes to enter the water. ALL OR NOTHING. Cortés Open: two locations, one sea, one passion that brings us together. Are you ready to discover Los Cabos from the sea?
