Olga Maria takes us on a day trip to the unique and ancient Stone Forest in Varna, Bulgaria
A little further on from the battlefield is a strange natural phenomenon at what is the only desert in Bulgaria.
The Stone Forest is a field of stone columns, some seven metres high covering an area of about 13 square kilometres.
These columns are hollow and have been formed by a process known as methane oxidation caused by tiny organisms, but it’s difficult to believe they’re not man-made.
The columns well worth a few snaps, but you can also have a look around the only desert on the European continent apart from Tabernas in Spain.
