Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Exploring El Arco de San Andrés guides divers through a progressively unfolding underwater landscape, starting gently over a rocky seabed. Initial descent targets a shallow 5-6 m (16-20 ft), where the rocky bottom supports early signs of marine growth.
From this initial area, topography quickly transforms, leading to a series of vibrant vertical walls. Vertical walls, often encrusted with colorful sponges and anemones, invite close inspection before terrain transitions into a broad, sloping sandy amphitheater.
Encountered at approximately 16 m (52 ft), this expansive area marks a significant shift in the dive's character, moving from confined wall diving to more open bottom exploration. A clear pathway from the sandy amphitheater leads directly to the site's most distinctive feature: a grand natural stone arch, the namesake of the location.
Navigating through this impressive geological formation is a highlight, offering a sense of passage and scale. Beyond the arch, divers access a prominent sand tongue that gradually descends, extending to the site's maximum depth of 31 m (100 ft).
A different ecosystem emerges in the deeper section of the site, where larger gorgonians frequently punctuate the sandy expanse. These provide shelter and feeding grounds for a distinct set of inhabitants not always found in shallower reef areas. An overall dive profile encourages progressive exploration, smoothly transitioning from shallower, reef-lined areas and walls to deeper, more expansive sandy stretches.
Divers can appreciate the gradual increase in depth and the changing environments encountered along the route.
