Geosites are places of particular importance for understanding history of the Earth. An example of such a place may be the Łuków site with fossil Ferdynandovian flora. The development of vegetation covers over 140 000 years of Pleistocene in this reference profile. The Łuków profile is one of only a few European complete profiles, in which two Ferdynandovian interglacial climatic optima are recorded. The scientific uniqueness of the Łuków profile was evidenced by numerous papers. However, the site was not analysed in terms of its usefulness for tourism and educational purposes. In order to fill this gap, the method of geosite evaluation has been used to evaluate geotourism potential. The following features of the site were evaluated: scientific value, educational value, state of the object (including threats), and accessibility. The evaluation was qualitative in a scale 1–5. We propose to establish the geosite named “Unique Ferdynandovian flora”. As a result, it will be possible to improve the accessibility and protect this site, as well as promote it as an object of nature tourism.
