96.9% Of beaches rated 'excellent': where to swim on the Bulgarian coast

Bulgaria has unexpectedly joined the EU leaders in bathing water quality. Almost all Bulgarian bathing areas received the top "excellent" rating.

For you, this means you can swim on the Black Sea coast without worry. Beaches stretch along the entire coast down to Sinemorets in the south. Many of them have a gentle entry into the sea, and the water is warm in summer.

We have gathered the key points from the latest report. Below you will find which resorts were tested, how Bulgaria compares with its EU neighbors, and when it is best to visit.

What the EEA report showed

💡 In short:

• Bulgaria is in the top three EU countries for bathing water quality.
• Only Cyprus and Greece are ahead, and the EU average is below Bulgaria's level.
• The rating is based on bacteria, not water clarity.
• The swimming season on the Black Sea runs from June to September.
• As of: report for the 2025 season, published in June 2026, checked in September 2026 on the official website.

The European Environment Agency (EEA) report came out this summer. It was prepared together with the European Commission and was based on samples taken over several consecutive bathing seasons.

The rating is based not on water clarity or color, but on bacteria. Laboratories test for E. coli and intestinal enterococci: these microbes indicate contamination from wastewater. A top score means the risk of catching a stomach upset or an ear infection is minimal.

For Bulgaria, the result is especially notable. Almost all of its bathing areas were rated "excellent," and the rest passed at least as "sufficient." There are no dirty beaches on the official list.

Which beaches and resorts were tested

The Bulgarian Black Sea coast is compact, and every major resort has bathing areas. From north to south, these are Kranevo, Golden Sands and Albena, then Varna with its suburbs, Sunny Beach, Nessebar, Pomorie, Burgas, and in the south Sozopol with its surroundings.

For you, what matters is not so much the rating of an individual beach as the overall picture: according to EEA data, all Bulgarian coastal bathing areas fell at least into the "sufficient" category.

Choosing a specific spot is easier based on your hotel's location. If you want a wide shore and calm sea, look at the northern resorts. If you want greenery and old towns, go south, from Nessebar to Sozopol.

How Bulgaria compares with the EU

Bulgaria's position stands out against its neighbors. Here is the top of the ranking by share of bathing areas rated "excellent" for the 2025 season (as of 09/2026, summary from the Bulgarian Ministry of Tourism).

The EU average is 84.8%, and Bulgaria is well ahead of it. Across the EU, about 22,000 bathing areas were surveyed: 85% received "excellent," 96% passed the minimum threshold, and 1.5% were rated poor (as of 09/2026, EEA report).

If you are traveling with children, clean water adds peace of mind.

When is the best time to go swimming

The swimming season on the Bulgarian coast usually opens in early June and closes in September. In July and August, the water is warmest, but there are also the most people, so you should book your hotel in advance.

If you want quiet and mild weather, choose the first half of June or early September. At that time, the sea is still or already comfortable, and the line for a sun lounger is shorter.

For a trip with children, the south is convenient: near Sozopol there are bays sheltered from the wind. In the north, in Albena and Golden Sands, the shore is wider and there are more hotels right by the water.

⁉️🤔 Frequently asked questions

Is it safe to swim on the Bulgarian coast?

Yes. According to the latest report, all Bulgarian bathing areas passed inspection: almost all received "excellent," and the rest at least "sufficient." In practice, you are swimming in water that was laboratory-tested for bacteria, not just visually inspected.

Which Black Sea resort is the cleanest?

The difference between resorts by official rating is minimal. So choose by format: Sunny Beach and Golden Sands suit those who like infrastructure, while Nessebar and Sozopol suit those who want to stroll through old streets by the sea.

What does the "excellent" rating mean?

It is the top score in the EEA report. It is given when bacteria concentrations in samples are consistently low for several seasons in a row.

When is the coast warmest?

The peak is in July and August. During these months, the sea is warmest, but there are also the most vacationers. The first half of June and September offer mild weather and fewer people, although the water may be cooler.

Should I book a hotel in advance?

In summer, especially in July and August, demand is high, so beachfront rooms go quickly. If you are traveling with family and want a specific hotel by the beach, book several months ahead. In June and September, there is more choice.

In short: where to swim on the Black Sea

For Bulgaria's Black Sea coast, the latest EEA report was good news. The beaches here stretch along the entire shore down to Sinemorets in the south.

If you want infrastructure and lively beaches: choose Sunny Beach or Golden Sands. If you want quiet and old towns: plan for Nessebar and Sozopol. And for a trip with children, choose the first half of June or early September. The water may be cooler then, but there are no crowds.
