Albena (Bulgarian: ) is a major Black Sea resort in northeastern Bulgaria, situated 12 km from Balchik and 30 km from Varna. Albena is served by the international airport of Varna. Albena is one of the purpose-built resorts on the Bulgarian Black Sea coast and has a uniform and unique architectural style. Many of the hotels are situated on the beach itself, exposed to maximum sunlight and providing direct access to the beach and sea. Albena is located close to other tourist, cultural and commercial centres and in the same time remains within well-preserved natural surroundings. Although it was built on an empty ground in the 1960s, now this is in fact a small resort town with its own downtown, streets, squares and even internal public transport dedicated little "trains" circulate on schedule along their routes within the resort.
