The Głębokie Lake has an elongated shape and is surrounded by hills covered with a deciduous forest. The Reknica River flows through this lake as well. However, this one is much deeper than the neighboring reservoirs, as it is 22 m deep is the deepest point.

The lake is surrounded by mixed forest, but with a predominance of deciduous trees. It is amazing that Kashubia is so different from other parts of Poland in this respect. While pine forests dominate in other parts of the country, in the area of Przywidz tourists will come across an extraordinary diversity of deciduous forests with alders, hornbeams, beech trees, oaks, maples, and rich undergrowth.
