Morskie Oko

Morskie Oko is a mountain lake in Tatra National Park in southern Poland (Lesser Poland Voivodeship). It lies in the Rybi Potok valley of the High Tatras at the foot of the Mięguszowiecki peaks and is the largest lake in the Tatras: about 860 m long, roughly 570 m wide and up to 50.8 m deep. The surface lies at 1,395 m, and the surrounding peaks rise around 1,000 m above it.

From the nearest road open to motor vehicles it is about a two-hour walk; many visitors take the horse-drawn carts run by local Górale. According to the national park, electric buses also run, for example from Zakopane to Włosienica, followed by a 1.7 km asphalt walk to the lake (as of April 2026; check timetables and tickets in advance). The PTTK hut at the lake is named after Stanisław Staszic and is the starting point for tours to Rysy (2,499 m), the highest peak in the Polish Tatras.

Practical notes: it can be cold and rainy even in summer, and in winter a short section of the route lies in an avalanche danger zone. Swimming in the lake and feeding the trout are forbidden.
