About Islas Cíes
Islas Cíes is a protected Atlantic island dive in the Vigo estuary with rocky reef faces, cliff-lined shoreline, and rich temperate marine life. Access is usually boat-based and permit-led, so the plan depends on park rules, weather windows, and whether you stay in sheltered water or work the more exposed outer faces.

Key Hazards
Boat trafficCold waterRestricted accessSurgeWaves
Safety Notes
Use an authorised operator, keep the weather window flexible, and treat exposed rock faces as surge-sensitive. Do not collect, disturb, or remove marine life.
Access Restrictions
Scuba diving in the national park requires authorization. Weighted freediving also requires permission, while surface snorkelling without weights is treated differently. Fishing, collecting, and seabed disturbance are prohibited.
Legal Notes
Cíes is a regulated national-park environment with protected habitats and visitor controls. Plan around park permissions, authorised transport, and condition checks.
Local Intel For Islas Cíes
Community notes to help plan your visit.
Scuba
Operator-led boat dives are the normal format, with scheduling based on conditions and park permissions. The site suits guided planning more than independent casual access.
Freedive
Weighted freediving is regulated like scuba inside the park; unweighted surface snorkelling is the lighter-access option.
Snorkel
Snorkelling works best in sheltered shallows and surface-only areas when the sea is calm. The outer faces are more exposed and less forgiving.
