Key Dive Site Facts
Dive Site Overview
Pozzo Cave, situated near Alghero, Sardinia, presents a distinct topographical progression for divers. Diving starts at a very shallow pinnacle, offering early opportunities to spot marine life such as octopus or barracuda among the rocks.
From this initial reef section, divers navigate along an intriguing wall that directly leads to the cave entrance. Inside, the limestone formation provides ample space for comfortable exploration, allowing divers to appreciate the subtle colors and geological features. This internal exploration proceeds before a slow, deliberate ascent to exit the cave at only 2 m (6.5 ft) depth.
At this remarkably shallow point, divers can witness their exhaled bubbles filtering through the porous limestone overhead, creating a mesmerizing "champagne glass" effect as they diffuse upwards. Combining elements of reef, wall, and cavern diving, this site offers varied underwater experiences suitable for those holding PADI Open Water Diver or PADI Advanced Open Water Diver certifications, without requiring extensive overhead environment training.
Best Time to Dive
Planning a dive at Pozzo Cave is best during the warmer, drier months when sea conditions are typically calmer. From April through October, the region generally experiences good dive scores, with significantly lower wave heights, reduced rainfall, and less wind. Air temperatures during this peak season range from approximately 15°C (59°F) in April to a high of around 26°C (79°F) in July, ensuring comfortable surface conditions. While specific water temperatures are not consistently reported for the site, they generally warm up as summer progresses, mirroring the air temperature trends. Conversely, the period from November to March often sees moderate dive scores, with cooler air temperatures ranging from 12°C (54°F) to 14°C (57°F), alongside higher wave heights and increased rainfall, potentially impacting boat access.

Dive Experience & Conditions
Pozzo Cave generally remains within comfortable recreational limits, reaching a maximum depth of 17 m (55 ft). An average depth of 10 m (33 ft) keeps divers well within no-decompression limits, supporting extended bottom times. Exploration begins at a shallower pinnacle before following a gentle wall descent that guides divers into the main cavern. This careful progression supports a gradual transition into the overhead environment, reducing potential stress. Exiting the cave is a unique experience, occurring at a shallow 2 m (6.5 ft) where divers witness the 'champagne glass' effect. Access to this saltwater site is exclusively by boat. Visibility inside the cave system usually depends on the water clarity outside and careful finning techniques, as disturbing the silted bottom can temporarily reduce sightlines. Divers should maintain awareness of their surroundings to avoid stirring sediment.
Dive Difficulty & Safety Guidelines
Despite its classification as a very easy dive, entering any overhead environment like Pozzo Cave requires adherence to specific safety protocols. Divers should maintain meticulous buoyancy control and use proper finning techniques to avoid disturbing sediment, which can reduce visibility and impact the delicate limestone formations. Always dive with a reliable dive torch, even during daylight hours, to properly illuminate the cave's interior and ensure safety. Following experienced local guides who are familiar with the site's layout is crucial. While PADI Open Water Diver and Advanced Open Water Diver certifications are useful, additional specialized cavern or cave training may be recommended for extensive penetration beyond the clearly visible exit point, though this site is designed for straightforward recreational entry and exit.
