Tatra Mountains and Morskie Oko

Morskie Oko is the largest and most famous lake in the Polish Tatra Mountains, the only alpine range in Poland and one of the last intact mountain ecosystems in Central Europe, with endemic species found nowhere else on Earth. The lake sits at 1395 meters above sea level in a glacial cirque at the foot of high granite walls, with a surface area of approximately 8.7 hectares and a maximum depth of 52.7 meters, making it the fourth deepest lake in Poland. The peaks surrounding Morskie Oko on three sides rise steeply to over 2000 meters, the tallest being Mnich at 2068 meters, and the fourth side is dammed by a terminal moraine deposited by a glacier that carved this basin during the last ice age. The lake is fed primarily by underground springs and a small stream from a side valley, and the outflow forms the Białka River, which flows north into the Dunajec and eventually the Vistula, connecting this high mountain lake to Poland's major river system. The name Morskie Oko, meaning Eye of the Sea in old Polish, reflects a belief in the medieval period that this lake was connected to the sea underground, and a legend of the knightry connected to the lake has been recounted in various versions over the centuries. The lake's extraordinary clarity and the depth of its blue-green colour are due to the low mineral content of its water and the lack of any significant organic disturbance.

The water of Morskie Oko is exceptionally clear, and on calm mornings the surface becomes a near-perfect mirror reflecting the surrounding peaks and the wooden cabin of Szczyty Miętusi below in complete stillness, one of the most photographed scenes in Polish nature. The trail to Morskie Oko begins near a parking area at Wsi Tatrzańska and follows a marked mountain path through a glacial valley for approximately 8 kilometers one way, a hike that takes two to three hours at a moderate pace, gaining roughly 900 meters of elevation as the path winds through forest and then alpine meadows before arriving at the lake. No motor vehicles are permitted in the Tatra National Park beyond the parking area, and the trail can become crowded during the summer high season, with visitors arriving throughout the day. The lakeside area itself has a small area where hikers rest and take in the view, with the surrounding cliffs and peaks forming a dramatic amphitheatre that is particularly striking in morning light when the first sun hits the granite faces above the water. The Tatra mountains are the most visited protected area in Poland, and Morskie Oko has been attracting visitors who hike to see this extraordinary mountain lake for well over a century.

The Tatra Mountains are the only alpine range in Poland and one of the last intact mountain ecosystems in Central Europe.

Morskie Oko is one of the most scenically dramatic glacial lakes in Europe, with exceptional water clarity and a near-perfect mirror surface on calm days.

The hike to the lake passes through a complete altitudinal sequence from forest to alpine meadow to high mountain environment.
