This chapter examines the topic of overtourism to propose management solutions for destination degrowth and resilience-building. The authors use a Delphi survey, having as a sample 104 tourism experts who have explored the issue of overtourism either conceptually or empirically. These tourism experts include academics, managers of tourism associations, journalists and German ministries' representatives. By exploring their different views the study aims to understand overtourism conceptually and to develop adequate strategies to tackle this phenomenon and its negative outcomes as well as to ensure successful (de)growth.
