The site is located in the cadastral area of the village of Andělka in the Liberec Region. Part of the relatively large Meandry Smědá Nature Reserve, it occupies a small section of this protected landscape.
The land managed by Refugium is in the shape of a triangle, bordered on one side by a railway line and on the other by the banks of the Smědá River, whose flow is gradually carving them. Its waters slowly enter the site, creating a rich aquatic environment. For the most part, however, the location consists of a floodplain with intermittent lush vegetation, which, amounting to about a third of the land, transitions into woody areas of mostly shrubs and willow trees. The Saňský Brook, which flows into the Smědá River within the site, is also an important feature.
