Nesebar

Nesebar is the next best place to visit in Bulgaria during the summer. This charming town on the Black Sea coast is known for its ancient ruins, edifices, and beautiful beaches. The old part of Nessebar is on an island with Byzantine-era fortifications and Roman baths that is connected to the mainland by a man-made walkway.

There's also the famous 11th century St. Stephen church nearby, which has an ornate altarpiece and numerous mural paintings. Aside from that, one can sunbathe on the beaches, participate in water sports, eat seafood, or have some crazy fun at the beachfront water park.
