Barranco is a rocky reef dive in Caleta de Fuste, Fuerteventura built around gorges, breakthroughs, and grottos in a rugged volcanic rock face. A sunken buoy in the southern section pulls in shoals of fish, while the sandy bottom and rock shelters hold rays, morays, trumpetfish, scorpionfish, octopus, and nudibranchs. It is a compact, terrain-rich site for divers who want structure and fish life rather than a long drift or a coral-first profile.
