Dive Site Location & Key Facts
Dive Site Overview
Site structure unfolds around two prominent rock formations, creating a dramatic underwater landscape of steep walls, numerous crevices, and a secluded small cave. Exploring here means encountering a substantial drop-off, where extensive rock structures descend dramatically to beyond 40 m / 131 ft.
A typical dive profile often navigates the upper to mid-sections, generally in the 20-30 meter range, which teem with intricate formations. These formations serve as a crucial habitat where invertebrate diversity is particularly rich, with hidden corners revealing unexpected life. Boat access is mandatory, typically launching from nearby points like Marina del Este, setting the stage for an offshore adventure.
Rock dominates the seabed, providing a complex, rugged environment that supports a varied ecosystem, from micro-habitats to larger resident species. Descending into these deeper sections demands precise navigation and buoyancy control, as the site's exposed location to open sea conditions can introduce significant water movement, testing even experienced divers.
The sheer scale of the rock face offers extensive exploration for those comfortable with deeper profiles and managing potential currents.

Best Time to Dive
Planning a dive at Piedras Altas means considering the distinct seasonal shifts, though the site consistently earns a 'Good' dive score year-round. The period from May to October generally offers the warmest air temperatures, ranging from approximately 20°C to 29°C (68°F to 84°F), coupled with the lowest rainfall, often less than 1 mm per month. During these months, wave heights also tend to be minimal, averaging around 0.6 to 0.7 meters. Water temperatures are at their warmest, between 22-26°C / 72-79°F. Conversely, the cooler months from November to April see air temperatures between 13°C and 19°C (55°F to 66°F) and slightly increased rainfall, typically up to 5.5 mm. Water temperatures during this period are cooler, around 13-18°C / 55-64°F, which might necessitate thicker thermal protection. Visibility remains good throughout the year, ranging from 10-30 m / 33-98 ft, but currents can be strong regardless of the season.

Dive Experience & Conditions
Descending into Piedras Altas offers an experience defined by a constant interplay of depth and significant currents. Divers frequently feel the water's pull, which makes controlled buoyancy and efficient finning absolutely crucial throughout the dive. Generally clear conditions offer visibility often ranging from 10 to 30 meters, providing expansive views of the substantial underwater structures. Water temperatures fluctuate widely; expect cooler winter temperatures around 13°C warming up to comfortable highs of 26°C in summer. Venturing to the lower formations, especially below 20 meters, brings unique invertebrate colonies into view. Look for distinctive 'dead man's hand coral' and 'cathedral sponges' swaying with the water movement, adding character to the deeper rock faces.
Dive Difficulty & Safety Guidelines
Approaching Piedras Altas demands a clear understanding of its advanced nature, primarily due to managing significant depth and strong currents simultaneously. Discussing prevailing current conditions with a dive center is essential before entering the water. Maximum operational depth extends beyond typical recreational limits, requiring appropriate deep diving certification.
Efficient gas management and a precise dive plan are crucial; bottom time can be limited, especially when diving on air. Carrying a Surface Marker Buoy (SMB) is strongly recommended for every diver, ensuring deployment during safety stops is possible.
Located within the Paraje Natural Acantilados de Maro-Cerro Gordo, a permit may be required for diving this protected area.

Why is Nitrox recommended for Piedras Altas?
Nitrox is strongly advised to extend useful bottom time, particularly when diving below 20 meters. Given the depths and the need for efficient gas management in potentially strong currents, Nitrox enhances safety and provides more time for exploration.
What makes Piedras Altas an advanced dive site?
Its advanced rating stems from the combination of significant depths, which can reach 40 meters, and strong currents. Divers must be proficient in managing both factors simultaneously, alongside careful gas planning.
What unique marine life can be seen at Piedras Altas?
Beyond common Mediterranean species, the site is known for distinctive 'dead man's hand coral' and 'cathedral sponges' on its deeper rock formations. Pelagic sightings, such as sunfish during spring and summer, are also possible, particularly in the blue water column.
Is a permit needed to dive at Piedras Altas?
Yes, Piedras Altas is located within the Paraje Natural Acantilados de Maro-Cerro Gordo, a marine reserve. A permit may be required to dive in this protected area; confirm with your local dive center.
How does Piedras Altas compare to Punta de la Mona?
Both are advanced deep dives in the La Herradura area, notable for strong currents and depths exceeding 40 meters. Piedras Altas is distinguished by its 'dead man's hand coral' and cathedral sponges, whereas Punta de la Mona features extensive gorgonian-covered walls. Your dive center can advise which site best suits current conditions.
