This dive site, Rondão Alvo, is situated just outside Porto de Mós Beach in Portugal. It is characterized by prominent rock formations that rise several meters from the seabed, creating numerous interconnected canyons and a distinct groove large enough for a diver to explore. Navigation involves tracing these natural rock structures and venturing through the many crevices and swim-throughs, with a torch recommended for exploring the darker sections of the groove. No specific historical context or story is associated with this site beyond its natural geological formation.
The marine life here is diverse and vibrant, featuring good sized and colourful gorgonian coral that adorns the rock formations. Divers can frequently spot congers and other eel species inhabiting the cracks and crevices within the rocky landscape. Snappers and various species of sea breams are a consistent presence, often schooling around the formations, contributing to a rich and active underwater ecosystem.
The site's shallow to moderate depth range, with an average of 10 meters and a maximum of 20 meters, makes it enjoyable for both scuba divers and freedivers seeking an interesting landscape. The intriguing topography of canyons and grooves, coupled with the colourful gorgonian coral, offers excellent opportunities for wide-angle and macro underwater photography. While no specific best time to visit is mentioned, the generally temperate waters of Portugal make it accessible for much of the year, with summer months typically offering the calmest conditions for diving.
