Tremiti – Italian Open Water Tour 2026

About the race

The Tremiti Islands, often called the 'pearls of the Adriatic,' offer one of the most spectacular settings for open water swimming in the Mediterranean. Located off the Gargano coast in Puglia, this pristine archipelago—comprising San Domino, San Nicola, Capraia, Cretaccio, and Pianosa—is a protected marine reserve defined by its dramatic limestone cliffs, hidden sea caves, and waters of extraordinary clarity. Swimming here is more than just a race; it is an immersion into a protected underwater world where the flora and fauna thrive in a virtually untouched ecosystem.

As part of the prestigious Italian Open Water Tour, the Tremiti stage carries a unique weight. The islands are steeped in history, famously linked to the legend of the Greek hero Diomedes, who is said to be buried here, lending an aura of myth to the 'Traversata di Diomede.' The event attracts a diverse community of swimmers, from dedicated competitive athletes chasing circuit points to amateur enthusiasts drawn by the allure of swimming in one of Italy’s most beautiful natural sanctuaries. The atmosphere is professional yet deeply celebratory, reflecting the warm hospitality typical of the Apulian region.

The organization is designed to be inclusive, offering multiple distances to ensure every swimmer—whether a beginner testing their limits or an experienced long-distance specialist—finds their challenge. The event is highly family-friendly, making it a perfect destination for those traveling with loved ones who wish to enjoy the island’s charm while others compete. The islands offer a serene escape from the mainland, where time seems to slow down.
