Prielom Hornádu, Canyon and national nature reserve in Spišská Nová Ves District, Slovakia

Prielom Hornádu is a canyon with steep limestone walls that cuts through roughly 16 kilometers of mountains in Slovakia, forming a narrow river valley. The Hornád River flows through the bottom of this rock formation, shaping the landscape over many centuries.

In 1906, Béla Hajts of the Hungarian Carpathian Association crossed the gorge by raft and gave the area the name 'Paradise of Upper Hungary'. Chains and metal footbridges were fixed from that same year, rope bridges were added in the Kláštorská roklina from 1960, and the Mountain Service trail was completed in 1974. The gorge has been a national nature reserve since 1964.

The path passes near the ruins of a medieval monastery that monks once built in a forest clearing high in the mountains. The site shows how people chose to live in this remote and difficult landscape, far from towns and cities.

The route runs between Čingov in the east and Podlesok in the west, both reached on the blue trail; a green branch midway leads to Kláštorská roklina in about an hour. The full gorge was not passable until the Mountain Service path was finished in 1974, and fixed chains and metal footbridges remain part of the walk. Sturdy boots and a head for heights are needed.

The canyon was first traversed in 1906 by Hajts Béla, head of the Igló branch of the Hungarian Carpathian Association, who crossed it by raft from Káposztafalva to Szepessümeg. He coined the name "Paradise of Upper Hungary" for the area, now the Slovak Paradise. A memorial cross on the trail commemorates four people who died in a helicopter accident during a rescue on 17 July 2015.
