The Krkonoše is our highest mountain range. As the height changes, so does the climate, meaning that the local flora is amazingly diverse. This is why the Krkonoše have always attracted collectors, botanists and all lovers of plants and flowers. This trail takes us through Obří důl – the deepest valley in the Czech Republic, which is a kind of microcosm of Krkonoše flora – and as we ascend from the spruces in the valley to the alpine tundra we learn about some of the prominent figures in botanical history whose names are inseparably linked to these mountains. The time needed to walk the trail is around 3 hours (although this does not include the return journey, for which there are a number of options).to cover longer distances).
