The gorge is characterized by some of the most interesting geological and geomorphological structures and area-specific natural ecosystems with little anthropogenic influence.

Wooden raft trips have been organized daily by Pieniny Gorals since the early 19th century — when their customers consisted mostly of guests of nearby Niedzica and Czorsztyn castles.

The landscape distinguishes it from surrounding mountains due to interaction of natural factors such as geological ground, relief, water, soil, climate, flora and fauna, and their evolutionary relationships.

From a botanical standpoint the Dunajec River Gorge serves as an example of area-specific vegetation dating back to the glacial age, even though the Pieniny Mountains were not glaciated.

From a zoological standpoint the valleys cut in Mesozoic rocks have an extraordinary importance for preservation of many species and fauna of the Carpathians.
