The contribution responds to the current legal regulations especially related with regard to the recent amendment of the Act on the Protection of Nature and Landscape in the Czech Republic. It focuses on some outdoor activities that may, in certain cases, come into conflict with the interests of protecting the most valuable natural areas. From this point of view, it may sometimes be problematic to run such activities. In this context, attention will be focused on organizational aspects, procedural point of view and also on the coming responsibilities of wildlife protection, respectively on term "Wilderness". The term "wilderness" is frequently discussed and used in widely varying discussions today among the professional and lay public alike, particularly in relation to the latest amendment of Act No. 114/1992 Coll., on nature and landscape conservation (the "Nature and Landscape Conservation Act" or "NLCA") by Act No. 123/2017 Coll. (the "amendment to the NLCA"). This usually occurs with reference to protection (and on the contrary also providing access) to core nature zones in national parks. One may encounter, inter alia, the commercial offer relating to wilderness guides. In the given context, the issue of quiet territories is also discussed. A key question remaining meanwhile is whether in our country, it is possible to truly designate any territories as wilderness. We encounter the term wilderness when we need to express something naturally formed (in forest management for example, under this term we imagine unmanaged forest growths left to their own fate).
