Jurkiškis stream is also called Melnyčėlė. It is one of the most interesting and impressive natural objects in Asveja Regional Park. The length of the stream is only 1.2 km, but during this short distance it "falls down" about 12 m. With its flow and meandering, it reminds a mountain stream, and the height of the slopes reaches 18 m. Its bottom is covered with boulders. In the riverbed lies a state-protected natural heritage object - the Jurkiškis stone, also called the "Child of Puntukas". Its girth reaches 5 m.

In the valley of Jurkiškis stream, next to it there is a 1.5 km long cognitive trail with information stands and arrows.
