Sunny Beach was established in 1958 as a state-run socialist tourism project.
The resort area is home to the Action Aquapark, which covers over 36,000 square meters.
The local coastline is bordered by natural sand dunes, several of which are designated as protected nature reserves.
It is geographically positioned between the UNESCO World Heritage site of Old Nessebar and the modern marina of Sveti Vlas.
The resort experiences approximately 1,700 hours of sunshine between May and October.
Sunny Beach is Bulgaria's largest seaside resort, located on an 8-kilometer stretch of coastline along the Black Sea. The beach features fine, natural golden sand and a shallow, sloping seafloor suitable for swimming. It functions as a purpose-built tourism hub rather than a traditional town, featuring high-density hotel clusters, outdoor entertainment zones, and water parks. The area is defined by a high concentration of bars, clubs, and discotheques centered around the central promenade. It holds Blue Flag certification, indicating high standards for water quality and environmental management. The resort is situated in a crescent-shaped bay between the historic town of Nessebar and the resort of Sveti Vlas.
The sand dunes located at the southern end of the beach provide the best contrast between the desert-like landscape and the sea.
Use the 'Breeze' water taxis that shuttle passengers between Sunny Beach and the neighboring Old Nessebar peninsula.
Sun loungers and umbrellas are concentrated in paid zones, but free-access sand stretches are designated by signage.
Carry small denominations of Bulgarian Lev, as some smaller beachside kiosks may not accept cards.
Avoid currency exchange kiosks located directly on the main promenade, which often offer significantly poorer rates than bank-affiliated offices.
The resort is highly seasonal; most infrastructure, beach services, and clubs operate only from May through September.
Beachwear is acceptable within resort grounds, but shirts and footwear are required in indoor shops and restaurants.
