Kosowinowe Oczko is one of the Tatra Mountains' best-kept secrets — a tiny, hidden pond nestled in the heart of Pyszniańska Valley, swallowed up by dense dwarf pine scrub. Small in size but rich in wild atmosphere, it's the kind of place that reminds you just how untouched parts of the Tatras still are.

Sitting at 1,527 m above sea level, in a section of the valley known as Siwe Sady, this little pond formed naturally in a hollow between glacial ground moraines — a quiet legacy of the ice age. It measures just 6.5 × 2 metres and reaches only 0.6 m in depth. The dense dwarf pine thicket surrounding it gives the pond its name: 'kosowina' is a regional dialect word for dwarf pine. In summer, the air here is thick with resin and silence; in autumn, the scrub turns golden and the pond reflects a steel-grey sky.

The pond lies to the west of the path leading up to Pyszniańska Pass, within the strictly protected zone 'Pyszna, Tomanowa, Pisana' of the Tatra National Park.

• Kiry (Kościeliska Valley trailhead) — follow the trail through Pyszniańska Valley towards Pyszniańska Pass; the pond lies just west of the path in the Siwe Sady area.

• Kosowinowe Oczko lies within a strictly protected zone of Tatra National Park — leaving the trail is prohibited.
• The pond is not officially accessible to tourists and can only be glimpsed from the nearby path.

Its charming name is a lovely piece of living mountain dialect — proof that even the smallest puddle in the Tatras has its own story and its own identity.
