Bulgaria in one day: Veliko Tarnovo, Bacho Kiro Cave and Dryanovo Monastery

Only one hour from Bucharest, Bulgaria is waiting to be revealed. The medieval fortress of Tsarevets in Veliko Tarnovo included in the UNESCO heritage with the cobbled streets and a unique view.
The Dryanovo Monastery is a step back in time; if Orthodoxy, it's an unknown religion for you, here you can feel the spirit of ancient times.
The highlight of the day is the Bacho Kiro Cave. The cave is a labyrinth of galleries and corridors where you feel like a fairy-tale underground world. With an approximate age of 46,000 years, human fossils found here are the oldest known in Europe. The entire area with the canyons of the Andaka and Dryanovo River it's one of the unspoiled nature corners of Europe.
