Dry spa as a factor of rural destination development

If we look at the energy as something that is all around us, then it is clear that energy as such can be used even for the purpose of tourism. Sofia's springs is the dry spa which is located in the national park and the fields with the strongest positive radiation in the world are the phenomenon. Whether this is a placebo effect or a real effect of bio energy circles, this location has the potential to attract "health tourists" from all over the world. The research took the whole 7 years, during which we analyzed motives and views of 687 foreign visitors of these springs who came to the springs by bicycles from 6 European countries. The analysis showed that the visitors believe that the dry spa helps them in solving health problems, including Covid-19, which invites medical science to examine it in detail and confirm or reject it. Anyways, that represents a backbone of health tourism development and can directly influence the rural destination development.
