Spain offers exceptional scuba diving in both the Atlantic and Mediterranean seas. Explore diverse sites from the shark-rich northern coast to the warm, transparent waters of the Mediterranean. Top dive spots include marine reserves like Cabo de Palos, Cabo de Gata, and the Columbretes Islands, as well as the Canary Islands’ La Palma, La Restinga, and Isla Graciosa. Discover vibrant coral reefs, colourful gorgonians, and thriving marine life—giant groupers, barracudas, seahorses, nudibranchs, octopus, and more—especially along the biodiverse Costa Brava.
Diving in Spain is possible year-round, but the best time depends on the region. Summer (June–September) offers the warmest waters (19–29°C) and peak marine life, ideal for spots like Mallorca and the southern coast. Areas near the Strait of Gibraltar—like Málaga, Granada, and Cádiz—enjoy diving almost all year thanks to mild conditions and marine mammals. In northern regions such as Galicia, Cantabria, and the Basque Country, waters are colder (14–18°C) with lower visibility but rich biodiversity. Spring and autumn are great for Costa Brava with thicker wetsuits or dry suits.
