**Preface**

In the tourism literature over the past two years, overtourism has been the most discussed topic in both the media and the scientific community. The excessive presence of tourists leads to congestion in attractive locations, excessive advertising, aggressive commercialization, and consequently a decrease in the level of aesthetic experience of tourists and the degradation of both natural and cultural resources. The effect of excessive visits by tourists is an increase in the prices of services, rents, and real estate, as well as the depopulation of districts exploited by tourism. In cities with a long history, it causes the gentrification of historical areas.

Excessive tourism, as shown earlier, results in exceeding the limits of socio-psychological possibilities, which results in the dissatisfaction of the inhabitants and protests against the development of tourism. Exceeding the capacity limits results in the dissatisfaction of the locals, which in turn affects the "local atmosphere" experienced by tourists.

The aim of this Special Issue is to showcase advances in current research and literature on overtourism and sustainable tourism as a way to eliminate or reduce the negative effects of overtourism. The authors of the articles presented scientific research on the phenomenon of overtourism from various points of view, challenges, and models, presenting its significance for tourism in regions, cities, as well as cultural and natural attractions. The 13 articles contain research on the attitudes of city dwellers towards overtourism, e.g., Krakow and Wrocław, the effects of tourism development in the Tatra National Park, and on the areas adjacent to tourist routes. It looked at night-time tourism and the sharing economy, as well as the possibilities of using business models to manage sustainable tourism. The articles published online are already very popular. They have been viewed by several thousand researchers and have been cited 300 times by other authors.

I would like to thank the authors for their participation in this Special Issue.
