Course

The Nara has its origin in the lake Polezkoje (Russian Полецкое озеро ) in the southwest of Moscow ridge, approximately 50 km west of Moscow in the west of Moscow Oblast. A few kilometers south it flows through the Nara ponds (Russian Нарские пруды ) before it continues to flow in a southerly direction through the densely populated Moscow region. A little later they reached Naro- Fominsk.

About 15 kilometers east of Balabanovo the river crossed the border to Kaluga Oblast. He now continues to flow mainly in the south to the northeast of Kaluga oblast, where he receives numerous small tributaries, before he turns to the confluence of the Istja to the east. The Nara again reached the boundary between the oblasts Kaluga and Moscow. Here it bends back into southern directions from, and marked now for a few kilometers of the border oblasts.

Shortly thereafter, she turns back to the east and then flows back to the area of ​​Moscow Oblast. In Stankowo she turns again to the south, and shortly afterwards they reached Serpukhov, where it flows into the Oka.
