An impressive outcrop was formed near Pūčkoriai by the waters of the Vilnia which slowly eroded the steep slope of the valley. At 65.2 m in height and 260 m in width, the Pūčkoriai Rocky Outcrop is the highest outcrop in Lithuania and is protected as natural heritage. The rocks seen in the outcrop are 18 to 20 thousand years old, and the strata of moraine and sand seem to be jumbled together and overturned one atop the other by the glaciers that passed through the soil layers like a bulldozer. Visitors of the outcrop get mesmerized by both its size and the beautiful views. From atop the Pūčkoriai Rocky Outcrop and its observation deck, one can admire the captivating vistas of the Vilnia River Valley, the twists and turns of the river bed, the buildings of Pūčkoriai Folwark, Pūčkoriai apple tree garden and the vistas of the Upper Pavilnys.
