What lies at the basis of all travel and tourism activities is ensuring that the many different products and services required by the tourist during his / her travels are provided by different organisations and businesses. Value Chain Analysis is a useful technique for the purposes of gaining an understanding of the contents of these products and services, and establishing an associative understanding between the organisations and businesses which provide these. The purpose of this study is to evaluate the accessible tourism market, which is an important market throughout the whole world, under the elements of the travel value chain. In this context, the concepts of accessible tourism, the accessible tourism market and the characteristics of the sub-groups which constitute the market are explained first, followed by an explanation of the concept of the travel value chain and an assessment of the accessible tourism market under the elements of the travel value chain.
