This dive site, Gruta Lagosteira, also known as the Lobster Cave, is a popular cavern dive located in the Berlenga Islands, Portugal. It serves as a natural passage for many divers exploring the region. The dive begins at the entrance, leading into a first room where divers can observe marine life hidden in crevices. Further exploration leads to a second, more spacious room, requiring flashlights for illumination. Both cavern rooms feature distinct air pockets in their ceilings, adding a unique element to the dive.
The cave is home to various marine species. Conger eels and triggerfish are commonly found camouflaged within the cracks and crevices of the first room. Scorpionfish and sea-urchins are also present, requiring divers to exercise caution due to their venomous and spiny nature, respectively. Triggerfish are noted for their biting behavior. While not explicitly mentioned, the cracks and rock formations likely harbor other small crustaceans and fish typical of Atlantic caves.
The best time to visit Gruta Lagosteira would likely align with the general diving season for Berlenga, typically warmer months when conditions are calmer. Divers should bring a flashlight to fully appreciate the second room and its inhabitants. Given its shallow average depth of 6 meters and maximum depth of 12 meters, it is highly suitable for both scuba divers of all levels and freedivers. Freedivers can particularly enjoy the accessible entrance and the ability to explore the initial cavern sections and air pockets on breath-hold. Always maintain buoyancy and avoid contact with the hazardous marine life mentioned.
