Kotelnica is a rugged ridge section in the High Tatras that runs right along the Polish-Slovak border — a wild, serrated spine of rock stretching from Gładki Wierch (2065 m) down to Czarna Ławka (1968 m). Standing on any of its summits, you have two countries at your feet and spectacular views in every direction.

The Polish side drops steeply into the breathtaking Valley of Five Polish Lakes (Dolina Pięciu Stawów Polskich), while the Slovak side descends into the Koprová Valley and its branch, the Kobylá Valley. The ridge itself is not a single summit but a series of ten distinct humps and notches — including Gładka Kotelnica, Wielka Kotelnica, Pośrednia Kotelnica, Mała Kotelnica and Czarna Kotelnica, separated by narrow passes. In summer the terrain is a world of grey granite and dwarf pine; in winter it becomes a serious alpine challenge covered in ice and snow.

• Valley of Five Polish Lakes refuge (Polish side) — approach via the ridge from Gładki Wierch; difficulty: demanding, suitable for experienced scramblers only
• Koprová Valley (Slovak side) — approach through Kobylá Valley to the base of the ridge; difficulty: demanding

• The ridge follows the Polish-Slovak state border — carry a valid ID document.
• Below Gładka Kotelnica, above Czarny Staw Polski, lies the Czarny Piarg — a steep scree field requiring care.
• The Usypisty Żleb couloir drops from Wyżnia Kotelnicowa Ławka toward Czarny Staw — this gully is avalanche-prone in winter and spring.
• The first known winter traverse was completed on 8 April 1925 by Adam Karpiński and Wilhelm Smoluchowski, reflecting the serious nature of this terrain.

Interestingly, the name 'Kotelnica' originally referred to the basin at the foot of the ridge — it was only through a historical mix-up that the name migrated up onto the ridge itself, making it one of the Tatras' more curious naming quirks.
