Key Dive Site Facts
Dive Site Overview
The journey into Pozo de la Luna begins by following a superb sheer wall, which guides divers to the grand cave entrance. This opening is typically found at a depth of around 13 m / 43 ft, marking the gateway to a distinct underwater world.
From here, a natural corridor stretches approximately 30 m / 100 ft, twisting and turning into the rocky coastline of Cap d’En Font. Traversing this passage, divers will notice the floor, which is uniquely paved with large, smoothly worn, rounded boulders, evidence of past geological forces.
Eventually, the tunnel opens into a circular chamber that features a prominent, circular hole in its ceiling, allowing ambient light to penetrate the cavern. Within this room, a distinct freshwater halocline creates a visible boundary; passing through it allows divers to surface into a small, enclosed air pocket known as the Moon Pool.
Sunlight's interaction with the water and the chamber's unique structure often provides a captivating light show, enhancing the exploratory feel of this challenging dive. Exiting the cave, divers retrace their path, often observing marine life found within the cave's recesses.
Best Time to Dive
Visibility at Pozo de la Luna can extend up to 30 m, and regional conditions generally favor diving through much of the year. Warmest air temperatures occur from June to September, averaging 23.9-26.4°C / 75-80°F, coinciding with the lowest average wave heights, often below 0.7 meters, and reduced rainfall, typically less than 1 mm per month. Calmer surface conditions prove crucial for safe boat access and entry, especially for a cave dive. Water temperatures range from 18-26°C / 64-79°F. While good dive scores are reported from February to December, summer months generally offer the most stable weather, translating to clearer water and easier navigation into the cave system.

Dive Experience & Conditions
Entry to Pozo de la Luna is possible either by boat or shore, though a boat entry is common for reaching the wall leading to the cave. Exclusively for experienced and advanced divers, it presents a significant challenge due to the nature of its cave environment. Maximum depth reached within the system is approximately 17 meters (56 feet), though some sources indicate up to 22 meters (72 feet). Average depths encountered are generally around 8 meters (26 feet). Water temperatures typically range from 18-26°C / 64-79°F, varying seasonally. Inside the cave, divers navigate through rock formations and a notable tunnel, requiring precise buoyancy and navigation skills. A freshwater halocline demands awareness from divers as they ascend into the air pocket.
Dive Difficulty & Safety Guidelines
Diving Pozo de la Luna presents the inherent challenges of a cave dive, requiring meticulous planning and strict adherence to established protocols. Given the confined overhead environment, proper cave diving certification is not just recommended but essential for safe exploration. Divers should be proficient in managing potential entanglement hazards, maintaining precise buoyancy in tight spaces, and understanding navigation within the tunnel. It's critical to carry adequate lighting, redundant air sources, and a dive computer to monitor no-decompression limits and depth. Always dive with a guide experienced in this specific cave system to navigate its winding passages and halocline safely.
