Overview
Asturias is not a resort-style tropical dive destination. It is a cold-water Cantabrian coast trip where local boats leave from Gijon, Candas, San Esteban de Pravia and Cudillero for rocky reefs, walls, gullies, caverns and macro life. The upside is a rare mix: urban beach life at San Lorenzo, dramatic coves like Playa del Silencio and Concha de Artedo, cider houses, fishing ports and easy access to inland mountains. Diving is best treated as weather-window dependent, with July to September offering the warmest water and easiest operator schedules. Non-divers will have plenty to do, from Cudillero viewpoints to Cabo Penas, Gijon promenades and Picos de Europa day trips.
Rocky walls, gullies, caverns, kelp-like algae, sponges and macro life create a very different profile from Mediterranean or tropical diving.
Gijon, Cudillero, Cabo Penas, Cabo Vidio, cider houses, Oviedo and Picos de Europa make the destination strong for mixed groups.
Most diving is guided by small local centres that know which coves, capes and estuary-adjacent sites are workable on the day.
Sheltered sites such as Deva Sur support courses and try dives, while Cudillero and Cabo-area sites can deliver deeper walls and cave-like topography for experienced divers.
Best time to go
June to September for easiest coastal planning
Warmest water near 20°C, lower rain frequency, easiest beach days and most predictable operator activity.
Main caution: Wetter, windier and colder, with water often near 13°C to 15°C and more exposedcoast disruptions.
