Key Dive Site Facts
Dive Site Overview
Descending into the Old Quarry, divers enter a compelling site steeped in history, where the indelible marks of ancient marble extraction remain clearly visible beneath the surface. Submerged sections, once dry rock faces, now form a complex series of sheer walls and intricate ledges, offering diverse exploration opportunities for those who appreciate geological formations.
This profound transition from intensive industrial activity to an active underwater ecosystem has sculpted an unusual and captivating topography, presenting a stark contrast to typical natural reef environments. Exploring these unique formations, divers navigate a landscape that feels both man-made and naturally reclaimed. While specific maximum depths for this particular quarry are not consistently reported across all sources, the majority of recreational dives here typically remain well within the 30 m (100 ft) range.
This depth allows ample bottom time for divers to meticulously observe the unique geological features and historical remnants. Along the quarry's intricate contours, divers can distinctly trace the precise lines and patterns left by ancient tools, experiencing a palpable sense of human history suspended in the blue.
Its distinctive structure, profoundly shaped by both human endeavor and the persistent forces of marine ecology, ensures a remarkably unique and memorable diving experience within the Attica region.
Best Time to Dive
While Greece generally offers favorable diving conditions through much of the year, the Old Quarry benefits from strategic seasonal planning for optimal comfort. Between March and November, the air temperatures are most inviting, ranging from 13.2°C (55.8°F) in early spring to a peak of 30°C (86°F) in July. During these months, the incidence of rain remains minimal, often less than 1 mm, creating clear days ideal for surface intervals. Conversely, the winter months, particularly December through February, see air temperatures drop to 11-12°C (51.8-53.6°F) and a noticeable increase in rainfall. Opting for the warmer, drier periods ensures more pleasant conditions both above and below the surface, enhancing the overall dive experience considerably.

Dive Experience & Conditions
Exploring the Old Quarry requires careful navigation through its unique submerged landscape. As a wall dive, divers encounter distinct vertical structures shaped by past human activity.

Dive Difficulty & Safety Guidelines
Navigating the Old Quarry demands a commitment to safety protocols appropriate for its unique structure. As a former quarry, some areas might present irregular surfaces or loose rock, requiring careful finning and buoyancy control to avoid disturbing sediment or damaging the environment. Always follow established dive paths and heed local dive center briefings. Maintaining close proximity to your buddy and being aware of your depth and air supply are crucial, especially when exploring deeper sections or wall features. Due to its historical significance, avoid touching or collecting any artifacts encountered. Always dive within your certification limits and consider the guidance of experienced local dive guides for this distinct site.
