This dive site, Olo, is characterized by a prominent high rock formation situated just off the breakwater of the port of Leixões in Portugal. Underwater, the rock's base extends to approximately 19 meters, while its peak rises to around 10 meters, offering a clear navigation point. There is no specific historical story provided for the rock itself, but its location near a major port suggests it has always been a known feature for local mariners and now divers.
Divers can expect to observe a variety of marine life, including different types of sponges and anemones adhering to the rock surfaces. The site is also home to various crustaceans. The predominant fish species found here are pout and rockfish, providing a typical representation of the local Atlantic fauna.
The best time to visit Olo for diving would typically align with calmer sea conditions, which are often found in late spring to early autumn. Its depth range of 10-20 meters makes it suitable for both beginner scuba divers and experienced freedivers looking to explore its rock formations and macro life. It is crucial to arrange boat access as it is not accessible from shore.
