In an era of rapid urbanisation and globalisation, travel and tourism provide a vital escape, offering opportunities to engage with new cultures, landscapes, and wellness experiences. Travel, especially in nature-based settings, presents a holistic approach to health by facilitating connections with natural environments and traditional wellness practices, far removed from the pressures of modern urban life. In Nature, Wellness and Sustainability in Health Tourism, a team of international academics explore the dynamic relationship between nature, health, and tourism, shedding light on how natural resources can be integrated into sustainable health and wellness practices. Through a blend of case studies, theoretical insights, and evidence-based research, authors demonstrate how natural environments such as forests, mountains, and coastal areas are being rediscovered as spaces for physical and mental rejuvenation. Nature, Wellness and Sustainability in Health Tourism not only educates readers on the health benefits of these settings but also inspires a renewed commitment to preserving them, encouraging sustainable travel practices that harmonise with nature’s restorative power. By examining nature-based health tourism through the lenses of environmental science, healthcare, psychology, and tourism management, chapters provide a comprehensive resource suitable for academics, researchers, and students. Appealing to both scholars and practitioners, particularly in tourism, health sciences, environmental studies, and cultural heritage, chapters offer insights that encourage cross-disciplinary dialogue and innovation.
