Many protected areas worldwide are mandated to provide visitor enjoyment and sustainable heritage conservation but face growing challenges and competition. To satisfy modern aspirational markets, parks must design meaningful experiences delivering long-lasting participant benefits that cultivate visitation rates and a conservation constituency. Transformative travel can deliver such benefits through participants’ psycho-physiological transformation but market insights critical for experience development in parks are lacking. Our systematic quantitative review of 126 transformative travel articles provides those insights, linking experiential characteristics, participant traits and motivations to experience outcomes according to five transformative travel typologies pertinent to parks: health and wellness, nature-based physical activity, spiritual, cultural and volunteering travel. We identified 35 travel motivations, 14 participant traits and 23 experience characteristics linked to transformation and 28 purposefully or incidentally realised benefits. Transformative travel improved participants’ psychological, physiological, social, economic and environmental conditions, as well as satisfaction with and destination loyalty towards parks. Socio-demographic characteristics and propensity for independent versus social travel shaped choice of travel experience. Our results are uniquely conceptualised in a transformative travel framework and transformative market niche model which we apply to sustainable experience development and marketing in parks. We identify implementation possibilities and areas for future research and monitoring.

Throughout the world, areas have been reserved for their exceptional environmental values, such as high biodiversity. Financial, political and community support for these protected areas is often dependent on visitation by nature-based tourists. This visitation inevitably creates environmental impacts, such as the construction and maintenance of roads, tracks and trails; trampling of vegetation and erosion of soils; and propagation of disturbance of resilient species, such as weeds. This creates tension between the conservation of environmental values and visitation. This review examines some of the main features of environmental impacts by nature-based tourists through a discussion of observational and manipulative studies. It explores the disturbance context and unravels the management implications of detecting impacts and understanding their causes. Regulation of access to visitor areas is a typical management response, qualified by the mode of access (e.g., vehicular, ambulatory). Managing access and associated impacts are reviewed in relation to roads, tracks and trails; wildlife viewing; and accommodations. Responses to visitor impacts, such as environmental education and sustainable tour experiences are explored. The review concludes with ten recommendations for further research in order to better resolve the tension between nature conservation and nature-based tourism.

Understanding visitor experiences is essential if park managers are to facilitate beneficial outcomes for both individuals and society. We investigated visitor experiences in a special model of thematically connected guided walking, biking, and 4WD tours in Australian national parks. Outcomes attained by first-time and repeat participants were assessed by questionnaires with more detailed insights from semi-structured interviews with repeat participants. Participants developed strong social ties with community members and experienced significant improvements in health, well-being, and competence, gaining a sense of achievement from mastering a challenge with positive implications for their lives beyond the tours. The tour series performed well in achieving visitor satisfaction, repeat participation, and word-of-mouth recommendation. The experience increased participants’ attachment to national parks, reinforcing their sense of environmental stewardship. The findings are especially relevant to efforts in parks and elsewhere to better integrate senior citizens into the community and provide opportunities to increase their physical, mental, and social well-being. Such opportunities become limited, for example, when people retire from work or suffer health impairment. The tour series proved an effective tool for outcome-focused park management, providing significant personal benefits to participants with positive implications for larger societal benefits, plus political and financial advantages for park managements.
