La Radikal

The waters off the Costa Brava, specifically between Calella de Palafrugell and Llafranc, possess a clarity that shifts from deep cobalt to pale turquoise depending on the sandy or rocky nature of the seabed. Swimming here feels like moving through a natural corridor shaped by the rugged promontories of the Catalan coastline. This section of the Mediterranean is characterized by its predictable thermal stability in early July, yet the currents around the Illes Formigues demand respect; they can create unpredictable shifts in water movement that require constant navigation adjustments. It is not uncommon to see local marine life during these crossings, though the true spectacle remains the submerged topography that remains visible through the water's surface as you approach the rocky inlets.

Historical currents and navigation

While you trace the coastline, you are essentially traversing the same maritime routes that influenced the naval innovations of the 19th century. Near the harbor of Barcelona, the legacy of Narcís Monturiol looms large, as he launched his revolutionary combustion-powered submarine, the Ictíneo II, in 1864, changing underwater navigation forever. This historical context of seafaring ingenuity adds a layer of depth to your own propulsion through the salt water. You will also pass landmarks like the Torre del Rellotge, a lighthouse-turned-clock-tower that served as the primary reference point for French scientists in 1791 when they calculated the standard length of the meter. These structures, visible from the water, serve as constant reminders of the human effort to measure and master the sea. Even the local folklore connects the landscape to the deep past, with the legend of the 'Barca Nona' suggesting that the wreck of the ninth ship of Hercules' fleet was found near the coast, an event claimed to have birthed the city itself. The shoreline has evolved significantly, including the area of La Barceloneta, which was once an island known as Maians before harbor developments connected it to the mainland in the 18th century. In recent years, reminders of more turbulent times have surfaced, such as the 70-kilogram unexploded Civil War bomb found near the seabed, which temporarily altered coastal access. Those interested in comparing these open-sea conditions with other regional events often look toward the CNB Swim or the historic 98th Port of Barcelona Crossing held later in the season. With distances ranging from a 50m sprint to a demanding 7km trek, the event maintains high safety standards, utilizing over 30 kayaks and specialized 'Angel Swimmers' to support participants across the different courses.
