Unlike most of its neighbours, Bulgaria is not particularly renowned for its islands - for a reason: it has but a handful of them, the largest being less than a square mile in size.
Some of those are just rocks off the Black Sea coast, others are in the Danube river. None of them are easily accessible unless you have your own boat. Still, some are at least interesting. For example, the St Anastasia island - formerly known as the Bolshevik, in the Bay of Burgas, was used as a place of pilgrimage, then a prison, then a weekend getaway spot; and now there are plans to convert it into a tourist attraction.
The island pictured here is south of the St Anastasiya. Under Communism, it was completely off limits as it was the only place in Bulgaria where wild cacti grew. Now the restriction is not very well kept, especially after the construction, just across the water from it, of one of those huge resort complexes typical of the southern Black Sea coast.
