Probably the most visited and most typical gorge of the Slovak Paradise is Kyseľ. The upper part is divided into Vyšný, Malý and Veľký Kyseľ. The Kyseľ Gorge together with the Sokol Valley and a part of the White Stream Valley form the Kyseľ National Nature Reserve.

One of the branches of this gorge, Veľký Kyseľ, is one of the wildest straits of the Slovak Paradise and is probably the most attractive for tourists. The unrestrained flow of the same brook flows through the ravine, which flows into the Little Kyseľ at the mouth and together they form the Kyseľ brook.

Gorge full of beautiful gates, caves and waterfalls. Pawlas Waterfall, Waterfall of Nature Conservationists, and Waterfall at Barrier are among the tourist-friendly waterfalls that will take your breath away and create a smile on your face.

The sad side of this gorge is the fact that the Veľký Kyseľ gorge was closed after one of the most dramatic fires in the history of the Slovak Paradise. Nature has recovered from this disaster for 40 years. Only a substitute route leading through the fire-free section was accessible to the public. Since 2016, however, the fire-affected part in the form of ferrata - Ferrata HZS Kyseľ is also accessible.

The starting point of the hikes to the gorge of Kyseľ and its individual branches is mostly Kláštorisko. The Kyseľa valley is also accessible by footpaths along the marked paths from Spišská Nová Ves and Dedinky.
