Zmarzły Staw Staroleśny — known in Slovak as Ľadové pleso, or 'Ice Lake' — is one of the wildest and most remote mountain lakes in the High Tatras, sitting at 2061 m above sea level in a raw glacial cirque far from any marked trail. Its name says it all: this lake often stays frozen well into summer.

The lake fills the floor of a deep glacial bowl, surrounded by the steep walls of Graniasta Turnia, Świstowy Szczyt and Mały Jaworowy Szczyt. Scree slopes tumble directly into the water, and almost no vegetation survives here — the landscape is elemental and untouched, as if the Ice Age never quite let go. The lake covers 1.722 hectares, reaches a depth of around 17.8 m, and is the largest of the 27 Stará Lesná Lakes. In early summer, ice still covers the surface; in autumn, the deep-blue water mirrors the grey rock faces above in breathtaking silence.

• Stará Lesná / Tatranská Lomnica (Slovakia) — yellow trail through Stará Lesná Valley; the yellow trail descending from Červená Lavka passes near the lake. Demanding, for experienced hikers only.

• No official hiking trail leads directly to the lake — reaching it requires off-trail mountain experience.
• The lake lies within TANAP (Tatra National Park, Slovak side) — nature protection rules apply at all times.

If you're looking for a place in the Tatras that feels truly untouched and wild, Zmarzły Staw Staroleśny is as close as it gets — a hidden glacial gem that rewards only the most determined visitors.
