The Parco delle Pietre Lanciate is one of the most unique places found in the Bolsena district. A unique place characterized by the bizarre geological formation deriving from the sudden cooling that is generated when a lava flow meets the water. The Parco delle Pietre Lanciate is the living embodiment of the singularity of nature, a place so sui generis so fascinating and gloomy that it is one of the main tourist attractions in the whole area of Lake Bolsena. Even the name of this park has an equally unique history, according to folk tales these peculiar stones are the petrifaction of lightning thrown by the ancient gods on the lake to punish the populations who had not respected some rites. Flying over the picturesque popular theories, what we know for sure is that the site of the Launched Stones represents one of the most particular geothermal manifestations in the whole region. An area that extends for hundreds of meters along the ridge invaded by dense native vegetation, which is part of the larger volcanic district and precisely by virtue of its beauty and originality is part of the geological heritage recognized by Unesco.
