||The park managers should be aware of the needs of their visitors so that they are satisfied with their experience during the visit. The park managers should balance the needs of nature preservation and interests of visitors in order to ensure preservation of nature values for the next generations because every visit leaves some kind of impact on the visited territory (Eagles 2009, Beardmore 2015). The European Charter for Sustainable Tourism in Protected Areas (ECSTPA) is of good assistance in retaining this concept in practical management. The goal of the present article is to show needs of local and foreign visitors and assessment of their visits in two national parks (NP) in Latvia. One of them, the Kemeri National Park (KNP), has earned (2012) the certificate of ECSTPA (Livina&Atstaja, 2015).
