The Pokljuka plateau is a threshold of many natural pearls, the most well-known being the Pokljuka Gorge. This nearly 2-km-long ravine is a remnant of a stream which, at the end of the last Ice Age, cut up to 50 metres deep into the limestone slopes above the Radovna. The waters gradually flowed away and the stream withdrew into the undergroun, leaving behind the largest fossil gorge in Slovenia.
In the Pokljuka Gorge we can encounter some kartic formations such as natural bridges, overhanging rock faces and caves. Along the preciptous slopes of the gorge, in some places only several metres apart, overhanging rocks alternate with widenings called "vrtci" (garden-plots). Across the narrowest part of the gorge, wooden bridges, called the Galleries of Prince Andrew, were built by the inhabitants of Gorje in 1930. Another attraction of the area is the Pokljuka Hole - a short shaft-like traversable cave which boasts three natural windows and two cave entrances. People have long used it as an easy passage to the more level terrain of Stara Pokljuka above.
The Pokljuka Hole is not visited by crowds of tourists but it undoubtedly deserves utmost attention and admiration.
