A forest nature reserve established in 1959 on the land of the village of Mała Wieś in the commune of Belsk Duży. The forest area in which the reserve is located is associated with the nearby estate of Mała Wieś. Historical sources indicate that the local larches were admired by King Stanisław August Poniatowski on July 21, 1787. The reserve, still on private land, was established in 1927 with the consent of the owners on an area of 7.44 ha in sections: 15a, b, c. During World War II, the complex was saved from devastation and cutting down, and even later the protected area was increased to 67 hectares (the Germans considered the local larches to be important for the Third Reich). After the war, a nature reserve was established on an area of 336.15 ha (Order No. 157 of the Minister of Forestry and Timber Industry of 5 May 1959), and eventually protected on an area of 332.15 ha.

The Modrzewina forest nature reserve was established in 1959 to protect a very valuable site of European larch (hence the name of the reserve). There is an approximately 5-kilometer nature trail running through here.

There used to be a path here, but as you can see, it is already in an advanced stage of liquidation. The lack of this path cost me an additional 5 km of detours :)
