Tourism has become one of the most dynamic sectors of modern economies, contributing significantly to regional development. However,
the rapid growth of tourist flows has led to the emergence of overtourism, which negatively affects local communities, natural environments, and the quality of tourist experiences. This paper examines legal and administrative instruments used to manage tourist
flows in the context of sustainable regional development. Particular attention is paid to the relationship between environmental law and tourism management, including the concept of “use exceeding common use” under environmental law. The study also analyses practical governance tools such as zoning, pricing policies, capacity limits, and stakeholder involvement. Using examples from Lithuania and Poland, the paper demonstrates that effective management of overtourism requires an integrated approach combining legal regulation, administrative measures, and innovative management strategies.
Changes caused by globalization changed consumer behaviour. It is passed from the era of items to the era of services causingemotions. On the other hand, it’s still a speculation, whether globalization affects the behaviour of Lithuanian people in choosingtourism. The research found that the Lithuanian residents still live in the era of items. For them is most important material safetyand image through items. To meet these needs Lithuanian residents prefer traveling abroad. Outbound tourism is attractive for thepopulation of Lithuania, but they frequently travel in Lithuanian territory. Lithuanian tourists are planning travel usually by themselves;this process is combined with rational. Economic, demographic and cultural factors have the greatest influence on the choiceof Lithuanians to make trips. Social, psychological and situational factors in the marketing mix have less impact.
