4. Seven Rila Lakes
Located in the Rila Mountains, these glacial lakes sing in the sunlight. They are each surrounded by mountainous hills down to the valley where the lakes sit, and are beautiful to walk through during the summer months (or the winter months, if you are more adventurous!).

3. Ledenika
Ledenika is a cave in the Balkan mountains, and contains ten separate halls. This cave was once full of water but only the Lake of Wishes remains – legend says if you plunge your hand into the ice-cold water and make a wish, it will come true.
