Mapping the Distance: An Analysis of Visitor Travel Distance to German National Parks and Biosphere Reserves

The ecologically valuable and unique natural and cultural landscapes of protected areas are popular nature tourism destinations. From a spatial perspective, travellers visit protected areas by moving from their place of origin to the destination for a temporary stay. This paper analyses the travel distances of day visitors and overnight guests to German national parks and biosphere reserves. National parks position themselves as both regional and national destinations. In contrast, biosphere reserve tourism is more regionally concentrated due to the proximity of biosphere reserves to urban centres, which are the primary places of origin for visitors. On average, visitors travel 278.6 km by car to visit a national park, taking 172.1 minutes (02:52 hours). Opting for public transport increases the average travel distance to 312.5 km, with a travel time of 284.5 minutes (04:43 hours). Visitors to German biosphere reserves travel 208.7 km by car, requiring 134.7 minutes (02:15 hours). When using public transport to visit biosphere reserves, the average distance increases to 234.0 km, with a travel time of 239.1 minutes (03:59 hours). The automated, GIS-supported distance analyses offer an innovative approach for assessing nature tourism catchment areas and the accessibility of protected areas, serving as a basis for effective spatial planning, development, and regional marketing.
