This book discusses how tourism between neighboring countries like Poland and Germany is hindered despite the Schengen Treaty. Taking protected areas in north-eastern Germany and north-western Poland as exemplary cases, it analyses the phenomenon of socio-economic and cultural barriers for cross-border tourism. It also presents the results of a representative online survey in both countries, and discusses socio-economic and geographical research on border areas, nature tourism in protected areas, national stereotypes and prejudices. As one of the very few source market studies on protected area tourism, it is relevant for scholars and practitioners (protected area managers, tourism professionals) alike providing them with insights into the implications for future research and tourism practice.
