The trail Trek into the world of Meshchera swamps begins near the village of Erlex and stretches through the pine forest to the swampy bank of the Pol River. On this trail you can see the typical landscape of the Meshchera pine forest, as well as the Sergievo swamp, which is located south of the auto road connecting the town of Gus-Khrustalny with the village of Urshelsky.
To the north of this auto road there is a huge Gusev swamp. It occupies a significant part of the Meshchera lowland. For many years there has been industrial development of peat and there are no hiking trails there. South of the road Gus-Khrustalny – village Urshelsky is a forest, and among the Pol and Buzha rivers there is a small Sergievo swamp, which can be seen on the Trek to the world of Meshchera swamps trail. The length of the trail is 5 kilometers.
The beginning of the trail is near the bus stop near the village of Erlex. The trail "Along the ancient Ryazan road" begins to the north of this place. There is a dirt road to the south of the auto road, where you need to walk 2 kilometers before starting the Trek to the world of Meshchera swamps. It is quite possible to drive this distance by car. Then the hiking trail begins, which stretches along the southern bank of the Pol River, but the river itself is not visible from the trail. The trail goes towards the village of Yagodnoye, but there is no access to it from the village, since Sergievo swamp is located there.

The trail stretches through a pine forest and only at the very end comes to the viewing point near Sergievo swamp, which is located between the beds of the Pol and Buzha rivers.
