Słowacki Raj · Letanovce, Košický Region
The longest ferrata on this list and the most famous gorge in the Slovak Paradise. Kyseľ stayed closed from the 1976 fire until 2016, when the mountain rescue service reopened it as a secured route: 1,470 metres of ladders, rungs and cables past four waterfalls — Barikádový, Kaplnkový, Karolíniho and Obrovský, where the ladders run right beside the cascade. The crossing itself is two hours and 180 metres of gain at grade C, but the approach from Čingov or Podlesok takes another four — budget six to eight hours in total and start in the morning. Above the gorge stand the ruins of the Kláštorisko charterhouse.

Free access, but only in season. Season: June – October.
The gorge is open only from 15 June to 31 October — outside those dates entry is forbidden for nature protection. The route is one-way, uphill only.
A ferrata set is mandatory and the helmet must be fastened. The gorge is wet by definition — the ladders beside the waterfalls stay slippery all season.
Ferrata sets can be rented at both park gateways — Čingov and Podlesok. There is nobody at the gorge itself.
Tickets: Slovak Paradise National Park entry ticket: €5 standard, €2.50 regional discount, €6 by SMS, €10 bought on the spot. A ferrata set costs an extra €10–20 to rent.
