Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
On a December morning in 1977, the freighter Aries, hailing from A Coruña and navigating the RÃa de Arousa, lost its rudder, rendering it unmanageable. This led to a collision with the submerged reef known as As Lobeiras Chicas, ultimately sinking the vessel.
Today, the Pecio Aries rests upright on a sandy bottom, allowing divers to appreciate the ship's entire profile, from keel to deck. This former cargo ship, which once traversed regular lines between Galician ports and Morocco, measures approximately 50 m (164 ft) in length. It lies at a maximum depth of around 21 m (69 ft), with its main deck and structures often found closer to 14 m (46 ft).
This relatively shallow depth makes it widely accessible for various certification levels, though wreck penetration is reserved for divers with appropriate specialty training. Its good state of conservation provides an excellent opportunity to explore various sections.
Divers can observe the ship's bridge and internal passages, witnessing the subtle effects of time underwater. This wreck dive is a fascinating blend of history and marine habitat, providing both structural exploration and vibrant encrusting life.

Optimal conditions expected
Current conditions near Pecio Aries show 29° air, 17° sea temperature, 0.8 m waves, and 21 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
Seasonal planning indicates optimal conditions for diving Pecio Aries primarily occur during summer, from June through August. That time offers the highest dive scores of "Good" and provides a stark contrast to other seasons. Air temperatures average between 19°C and 21°C (66.2-69.4°F) during these peak months, ensuring comfortable surface conditions. Minimal rainfall, with monthly averages ranging from just 1.38 mm to 2.78 mm, significantly reduces surface run-off that could impact visibility. Wave heights remain at their lowest, generally between 1.0 m and 1.2 m (3.4-4.1 ft), indicating calmer seas. Consistent long-term water temperature data isn't consistently reported for this specific site in our system; however, individual dive logs suggest temperatures around 16°C (61°F) in spring conditions. Divers should anticipate similar or slightly warmer waters during summer. Conversely, winter months, particularly January and February, present "Unsafe" or "Poor" dive scores due to higher wave heights averaging over 3 meters (10 ft) and increased rainfall, making diving considerably more challenging. Summer planning ensures the best opportunity to explore this historic wreck.

Dive Experience & Conditions
Entering the waters above Pecio Aries, divers are typically met with high visibility, sometimes reaching 30 m (100 ft) on favorable days, which significantly aids the initial descent. Resting upright on a sandy seabed, the vessel presents its entire form clearly to approaching divers. While generally considered a low-difficulty dive, divers should prepare to assess and adapt to prevailing flow conditions, as manageable currents have been reported. A max depth of 21 m (69 ft) allows for generous bottom times and thorough exploration. Open Water certified divers can comfortably explore the exterior, while advanced wreck specialists may venture inside. Surrounding the wreck, a sandy environment contrasts with the structure's growth, creating distinct visual elements. The site offers a straightforward yet rewarding wreck experience, suitable for many skill levels, allowing focus on ship details rather than battling harsh conditions.
Dive Difficulty & Safety Guidelines
Approaching the Pecio Aries requires an understanding of general wreck diving safety, even though it's classified as a low-difficulty site for external exploration. While typically accessible for Open Water divers, the presence of currents, as sometimes reported, means divers should monitor local conditions and plan their dive accordingly. Maintaining excellent buoyancy control is crucial to prevent disturbing the sandy bottom or damaging the wreck's structure and its delicate marine inhabitants. For those considering penetration, a wreck diving specialty certification is mandatory. The interior, particularly the bridge and other passages, presents overhead environments that demand specific training, appropriate equipment, and a clear understanding of navigation and emergency procedures. Never enter a wreck without proper training. Adhering to these guidelines ensures a safe and respectful encounter with this submerged historical artifact.
