This paper explores the concept of accessible tourism and its links with triple bottom line sustainability. Accessible tourism is reviewed through some of its central features including dimensions of access; universal design; and the nexus between ageing and disability. The triple-bottom-line (TBL) is then examined to better understand the financial, environmental and social considerations that arise from accessible tourism. The research design used in this explorative research incorporated a case study approach where a business case study instrument was developed. Methods included a review of management information systems, in-depth interviews with key informants, observation and participant observation. The study results revealed that rather than accessible tourism being a single construct, it forms one critical dimension of a series of interrelated, overlapping and interdependent business arrangements that extend beyond the business entity through a series of social networks within the destination region. It is argued that to properly satisfy the accessible tourism market, a more sophisticated understanding of accessible destination experiences is needed by tourism operators. The case study illustrates the considerable size and multi-niche markets served by accessible tourism destinations, the good fit between accessible tourism and TBL sustainable tourism, and the need for further research.
