Why not visit Lake Hancza, Poland deepest lake? Hancza has a steep-sloping bed that is punctuated by small caverns, is almost 110 metres deep and contains crystal-clear, well-oxidized water that is inhabited by rare species of fish. In a word, the ideal place for underwater exploration.

Visitors are amazed by the Table Mountains (Gory Stolowe) and their fabulous rock formations. These are the only mountains in Poland with a plate structure that is made up of horizontal layers that has been carved by the wind and water into formations which have inspired names like the Eye of the Needle, Horse's Head or Mammoth.

There is one area of Poland that can be said is truly exotic. This is the Bledow Desert which can be found to the north-west of Krakow and is a desert area that is probably the largest in Central Europe. It is only 10km long and 4km wide but it is large enough to create desert mirages if climatic conditions are correct. However, the most unusual sand formations can be found in the Slowinski National Park on the Baltic coast. These are the monumental shifting dunes which move at speeds up to 10 metres per year and have already engulfed several villages.

It is always worth visiting the Biebrza Marshes, the most extensive marshlands in Central Europe, where visitors may get an opportunity to catch sight of bird species like short-eared owls, snipes, curlews, cranes, grouse, terns and many more. Almost 300 different species of marsh-dwelling birds live here, including some of the rarest kinds, which have chosen Poland's largest national park, as their breeding ground.

Visiting the Bialowieza Forest, the last remaining primeval forest on the European plain, is a must for every nature lover. In the forest, apart from the 400 or so wild bison, tourists can follow the Oak Trail, which winds between centuries-old oak trees that have been named after former Polish and Lithuanian kings and dukes who once used to hunt in this forest.
