The Black Sea coast remains the most-preferred summer holiday destination for the Bulgarian citizens in 2017, a quick survey of Gallup International sociological agency shows. Over 1.3 million adult Bulgarians have spent their summer holiday at the Bulgarian Black Sea coast this year and another 500,000 are expected to do the same until the end of the summer season. It turns out that the Bulgarian Black Sea coast would be visited by nearly half of the Bulgarian population, if sociological surveys include children in their statistics. Nearly 350,000 Bulgarians have spent their holidays abroad this summer. As a whole, over 60% of the Bulgarian nationals have spent their holidays or will go on vacation away from their place of residence.
