The book explores the theme of active sports tourism, which includes extreme sports, those in contact with nature, and the so-called ‘slow adventure’. It shows that it is a rapidly developing sector because it is less expensive than other tourism segments, produces more economic impact for the host territory and is more attentive to respect for the environment. The book provides a complete picture of the phenomenon at an international level, investigating its territorial development, the profile of sports tourists, the role of communication and host branding, the contamination between sports tourism and other forms of tourism, and the prospects for future development of this sector.
