Common questions about swimming in Bulgaria

Is it safe to swim in Bulgaria?
Mostly yes. 97% of Bulgaria's 96 officially monitored bathing sites hold the top "Excellent" class in the 2025 assessment, and not a single one is rated Poor.
Which beaches in Bulgaria should I avoid?
None. No bathing site in Bulgaria carries a Poor classification in the 2025 assessment.
Where is the water cleanest in Bulgaria?
58 sites have held the top rating five seasons running — a far better signal than a single good year. Around Sunny Beach, Varna, Burgas you will find the densest clusters.
How often is water quality tested in Bulgaria?
Through the whole bathing season. National sanitary authorities sample each official site for E. coli and intestinal enterococci, report to the European Environment Agency, and the published class reflects the last four seasons combined.

Ratings are the official season-long classification, computed from the last four seasons of sampling — not a live reading. After a storm any site can be temporarily worse; local advisories win.
