I visited this tWHS as a pleasant detour after visiting the Madara Rider WHS. Although there is a parking lot hidden just behind the site proper, it didn't feel safe at all to leave my car there so I decided to park my car in the very wide shoulder of the main road (as did most other local cars). The main road passes right through the pretty natural landscape and there are very minor limestone formations also on the other side of the road although the beware of snakes sign and the overgrown grass made me just watch from a distance.
The natural monument landscape on the other side is really beautiful to explore. It is quite strange to explore what now looks like a desert landscape in the middle of never-ending sunflower fields (a very ugly looking industrial scale facility is the only eyesore around apart from the main road itself). It has been also dubbed as a "stone forest". The limestone formations are actually tubular stone pillars which formed around "rising methane-bearing fluid plumes". These desert rock formations are believed to represent an exceptional record of paleo-hydrocarbon seep system. The pathways of fluid circulation are recorded as columns set in sand, producing a desert-like landscape. Apart from the geological importance of the natural monument, Pobiti Kamani is also considered to emanate some sort of cosmic energy.
The Pobiti Kamani Natural Monument occupies an area 8 km long and 3 km wide, with seven groups of stone pillars. The main group which can be visited quite easily is known as "Dikilitash" and includes over 350 stones. Most of the stone pillars are five to seven metres high with a thickness that varies from about 30 centimetres to 3 metres across. The stone pillars are almost all hollow cylinders, mostly filled with sand, and some contain a number of fossils, including petrified remains of numulites, mussels and giant snails. A large number of the stone pillars are also considered to be simulacra, that is accidental natural formations which happen to resemble human faces or other other objects. These appear on a variety of rock surfaces and many have been accredited with names and personalities by the locals, for example the soldier, the lonely man, the small throne, the big throne, the camel, the poodle, the forked stone, the mushroom, the heart, the stone of fertility, the family and the stone of the divine love. The latter formation is made up of a stone pillar that eroded and tumbled down to the ground, but at its core it forms a silhouette of a heart.
The area around the Pobiti Kamani Natural Monument is also blessed with a vast range of flora and fauna. This barren scrubland is in fact home to 21 species of birds, 7 mammals (many rodents roaming around on a quiet day) and more than 240 varieties of plants, many of which are quite rare. That said, I'd be surprised if this ever becomes a WHS, mostly since natural formation hypothesis is still that ... a hypothesis and is still being studied at the Oceanographic Institute in Varna and worldwide. Still, it is a worthwhile detour while in Bulgaria if you have time to spare.
