Climbing and skiing near Poland's famous Morskie Oko lake is also forbidden to protect the nests of a rare falcon species in the area.
Meanwhile, rescuers have issued avalanche and weather warnings for the entire Tatra mountains range.
The Tatra Volunteer Rescue Service (TOPR) and the Tatra National Park at the weekend warned hikers that trails in the mountain range were covered with a thick layer of fresh snow, with deep drifts forming in places.
The avalanche risk level was defined as significant, with six avalanches reported across the mountain range only on Friday.
Brown bears are the largest mammals inhabiting the Tatra mountains. They usually hibernate from November to March. Adults weigh around 300 kg and live up to 50 years.
