Independent, data-driven guides to every Blue Flag certified beach — water quality, facilities, season data and travel tips.
About the Programme
The Blue Flag is one of the world's most respected environmental awards, granted annually to beaches, marinas, and sustainable boating operators that meet strict standards set by the Foundation for Environmental Education (FEE). It has been running since 1985 — first in Europe, now covering more than 50 countries across every inhabited continent.
To earn a Blue Flag, a beach must satisfy 33 criteria across four categories: bathing water quality, environmental management, safety and services, and environmental education. Certification is not permanent — each beach is assessed and independently verified every year. A beach that fails any mandatory criterion loses its flag that season.
The water quality standard is the most important requirement. Certified beaches must meet the EU Bathing Water Directive's Excellent or Good classification, based on regular testing for intestinal enterococci and Escherichia coli. Results must be displayed publicly at the beach throughout the swimming season. This makes Blue Flag one of the most transparent beach quality programmes in the world.
Beyond water, certified beaches are required to have trained lifeguards on duty during bathing hours, provide first aid equipment, offer disabled access, manage waste responsibly, and run at least five environmental education activities per season. The criteria are not optional extras — they are pass/fail requirements.
For travellers, the blue flag flying above a beach entrance is a reliable shorthand: the water has been tested, the facilities are up to standard, and the beach is actively managed. It does not guarantee perfect conditions on any given day, but it does mean the beach has consistently met a high bar over multiple seasons.
