Oceanman Costa Azahar — Benicàssim

From the golden curve of Playa Morro de Gos in Oropesa del Mar, marathon swimmers trace the Mediterranean coastline of the Costa Azahar all the way to Benicàssim. Oceanman Costa Azahar is an open water swimming event held in May in the coastal waters of Benicàssim, in the province of Castellón along Spain's Mediterranean shore. Organized by OCEANMAN, the gathering brings together a full range of open water challenges suited to varying levels of experience. Swimmers can take on distances ranging from a 500-meter sprint and mid-distance journeys of 1,500 and 2,000 meters up to 5,000-meter and 10,000-meter endurance courses. In past editions, the premier ten-kilometer course has taken athletes along a coastal path recognized for its high ecological value, traversing temperate spring sea conditions.

That marathon route sets out from Playa Morro de Gos in neighbouring Oropesa del Mar, swimming south in parallel with the old coastal rail path to reach the beaches of Benicàssim. The starting beach extends for more than two kilometres along the coast, bounded to the north by Playa de les Amplaries and to the south by Punta de las Lanzas. Its fine sands have carried the Blue Flag designation since the late 1990s, offering an expansive launch point directly into the open Mediterranean.

Desert de les Palmes: coastal shelter and sea panoramas

Rising immediately inland behind the beaches, the coastal mountain chain of the Desert de les Palmes forms an imposing natural barrier. This protected natural reserve ascends to a height of 729 meters at Mount Bartolo and shields Benicàssim from harsh northern winds, keeping the coastal waters remarkably settled for swimmers. On days with clear Mediterranean skies, the highest vantage points across the Desert of the Palms open up views extending all the way out to the volcanic archipelago of the Columbretes Islands. Down where the foothills meet the shoreline, a dedicated 5.5-kilometer path for walkers and cyclists skirts the rocky edge of the coast between Benicàssim and Oropesa del Mar. Swimmers navigating the offshore line track this very same passage from below, watching the coast slide by with every stroke.

Torre de la Sal and Tossal del Mortórum: ancient shores

Human life along this coastal plain reaches deep into prehistory, with evidence of occupation dating back more than 300,000 years. Ten kilometres from the race venue, the archaeological site of Tossal del Mortórum preserves traces of a settlement established at the start of the second millennium BC. A collective burial tomb built three hundred meters from the settlement served the community during that same Bronze Age era, containing the remains of at least five individuals. Further along the shoreline, an ancient maritime anchorage emerged at Torre de la Sal during the seventh century BC. Between the second and first centuries BC, the harbor grew into one of the most significant Iberian settlements on the entire Castellón coast.

Torre del Rey and the British raid at Oropesa

Just over eight kilometres up the coast from Benicàssim, maritime history comes into view at the fortified headland of Oropesa del Mar. On June 9, 1801, that harbor became the theatre of a fierce naval bombardment when two British Royal Navy brigs, HMS Speedy and HMS Kangaroo, sailed within striking distance of the port. The British vessels dropped anchor only 230 meters off the coast and 460 meters from the town to duel with the coastal fortifications at point-blank range. The engagement ended with the sinking or grounding of several Spanish defenders, including gunboats and a twenty-gun xebec, after HMS Speedy alone poured roughly 1,400 artillery projectiles into the bay.

Years after the naval battle, navigation around the rugged promontory was secured by the construction of the Oropesa cape lighthouse, raised beside the ancient King's Tower in 1857. Standing at the geographic headland that divides the coastline of Castellón province, the light originally operated with olive oil and paraffin before being converted to electricity in 1924. Today it serves as a historic sea beacon above Oropesa.

Voramar to Torre de Sant Vicente: the Benicàssim promenade

The swimming routes conclude along the beachfront of Benicàssim, where six kilometres of continuous sandy shore are tied together by a long pedestrian promenade. Voramar Beach is celebrated for villas constructed along its shoreline. Further south along the promenade, swimmers reach Playa de la Torre de San Vicente, a 650-meter beach nestled between the shores of l'Almadrava and Els Terrers. Guarded by the historic watchtower of Sant Vicente, the beach features an anchored floating platform resting in the bay as a swimming and meeting point. Stepping out onto these firm sands after miles of open sea, swimmers find themselves at the vibrant heart of the town's seaside life.
