Galicia

Diving in Galicia offers a unique glimpse into the cool, nutrient-rich waters of Spain's Atlantic coast. Unlike the Mediterranean, this region is characterized by lush kelp forests, dramatic rocky reefs, and vibrant underwater life thriving in its sheltered 'rías' (estuaries). The cornerstone of Galician diving is the Atlantic Islands of Galicia National Park, particularly the Cíes Islands, which boast protected ecosystems and stunning submerged landscapes. This is a destination for adventurous divers seeking biodiversity over tropical temperatures, exploring a wilder, more temperate side of European diving.

Conditions in Galicia are challenging but rewarding. Water temperatures are cool year-round, typically ranging from 12-18°C (54-64°F), requiring a thick wetsuit or drysuit. Visibility can be variable, often between 5 to 15 meters, influenced by tides and plankton. Divers should visit to experience the incredible density of marine life, from octopus and lobsters to colourful nudibranchs. The unique combination of rugged coastal scenery, exceptional seafood, and an underwater world teeming with life makes Galicia a truly special and off-the-beaten-path dive destination.
