In my article I woud like to find answers for the question how frequently and effectively the region’s business leaders in Northern Hungary participated in various development programs, as regards investments in health tourism, what developments have been made mainly in the area, what the positive effects of these developments were in the life of businesses, whether the businesses (leaders) feel successful, and how their success was manifested. I carried out a questionnaire survey among enterprises. From the data I calculated mean, SD and spectrum and examined the crosstab correlations as well, and the Cramer’s V associate coefficient and Contingency coefficient. The results of the correlation tests could be summarised as the following: According to the survey, the number of the medium-sized enterprises being involved utilised a significant proportion of their development funds, compared to the micro and small enterprises. Although the idea of spas winterizing their pools was not considered an important development, both the adventure and wellness elements were important for the construction of thermal baths. In the case of hotels, the expansion of wellness elements and other additional services together with the development of marketing activities played an important role. Besides the positive business publicity, enterprises see the positive effects of the investment in the increase of their income; the success can be the result of the adequate supply of components, the professional management and that of positive image.
