If you are interested in peaceful hiking in nature, away from the noise of the city, this tour is for you. We’ll walk in the remains of an ancient sea, where mollusks and sea creatures dominated. Feel a part of the way in the natural history and touch a piece of it. When the empire of the dinosaurs was rising, most of the Bulgarian lands were below the sea. 150 million years later, this sea is Ponor mountain. Now that carst mountain has limestones from the Triassic and Jurassic period.
