Accessibility problems often prevent people with special needs from enjoying facilities and services in tourist destinations. It is an institutional obligation, as well as a social necessity, to “open the doors” of tourism for everyone, within the concept of tourism-for-all concept. Moreover, accessible tourism is considered an important economic opportunity for touristic destinations, taking also into account the ageing of population over the last decades. In order to strengthen the touristic brand of the Pieria Region and promote the area as an “Accessible Tourist Destination”, an online platform has been developed under the responsibility of the Pieria Organization for Tourism Development and Promotion, with the scientific and technical support of the International Hellenic University. The platform provides complete information on accessibility infrastructure in respect to route accessibility (obstacles in pavements, ramps, etc.) accessibility issues for points of cultural and tourist interest (PoIs). In this paper, the key functionalities of the platform are presented through the case of Platamonas, Greece, where the platform has been tested and results have been validated.
