Lasek Bielański

Lasek Bielański is a nature reserve in Warsaw's Bielany district, spanning 130 hectares with different forest types and gentle slopes descending toward the river. The area contains ancient oak trees and a wide range of plants and animals found nowhere else in the city.

King Władysław IV brought Camaldolese monks to Polkowa Mountain within the forest in 1639, which led to the area's name. Later, a Russian fort stood here as a remnant of military control during the period of Russian rule over the city.

The forest's name comes from the white-robed Camaldolese monks who settled here in the 17th century and shaped the area for centuries. Visitors can still sense this monastic heritage in the quiet woodland landscape today.

The area has well-marked trails that make it easy to explore different parts of the forest on foot. Visitors should be prepared for wet ground and uneven paths, especially in the steeper sections toward the riverbank.

The forest is home to rare beetle species including the hermit beetle and great capricorn beetle, living in oak trees between 300 and 400 years old. These insects are specialized on old, thick trees and cannot be found anywhere else in Warsaw.
