About This Site
Los Arcos ("The Arches") is Calpe's signature dive and the flagship site of every dive centre working the Peñón de Ifach. It lies at the foot of the north face of the iconic 332 m limestone rock, where over the ages huge boulders have tumbled from the cliff and piled up on the seabed into a maze of natural stone arches, swim-throughs and passages. Divers drop to sand and posidonia at about 9 m and immediately meet the first and largest arch — a broad window into the blue framed with gorgonian and patrolled by shoals of two-banded bream — then thread a labyrinth of smaller arches and boulder tunnels down to a maximum of roughly 15 m. Shallow, sheltered and endlessly photogenic, it is an easy, relaxing dive that suits everyone from freshly certified Open Water divers to macro hunters.

Los Arcos sits on the north face of the Peñón de Ifach, with the massive 332 m rock rising immediately to the south and southwest and completely blocking the S-SW sector, and the mainland and Calpe headland shielding the west. Across the NNW-N window the Calpe-Benissa shoreline lies only 1-2 km away, so northerly wind-sea arrives short and clipped; the genuinely open water is the east-north-east to east, past Cap d'Or and Cabo la Nao — the direction of the Levante, the region's dominant wind-wave with the longest open-water fetch, which is what builds surge and chop on this face and forces dives to be relocated to the sheltered south side of the rock. Southerly and westerly weather leaves the site calm in the lee of the Peñón; there is no true ocean swell in this part of the western Mediterranean, so conditions are driven by local wind-sea, and the site is essentially non-tidal.
