Book excerpt: The Routledge Handbook of Religious and Spiritual Tourism provides a robust and comprehensive state-of-the-art review of the literature in this growing sub-field of tourism. This handbook is split into five distinct sections. The first section covers past and present debates regarding definitions, theories, and concepts related to religious and spiritual tourism. Subsequent sections focus on the supply and demand aspects of religious and spiritual tourism markets, and examine issues related to the management side of these markets around the world. Areas under examination include religious theme parks, the UNESCO branding of religious heritage, gender and performance, popular culture, pilgrimage, environmental impacts, and fear and terrorism, among many others. The final section explores emerging and future directions in religious and spiritual tourism, and proposes an agenda for further research. Interdisciplinary in coverage and international in scope through its authorship and content, this will be essential reading for all students, researchers, and academics interested in Tourism, Religion, Cultural Studies, and Heritage Studies.
