The first part of this section of the Forest Trail winds along the magnificent Piusa River valley, then, at Härmä village, it turns towards Obinitsa, an important cultural centre of Setomaa, the Land of Setos. Here you can discover the traditions of the local Seto people. After Obinitsa, the Forest Trail leads through beautiful pine forests rich in heather, descends back into the depths of the Piusa River valley and turns east at Piusa caves. From there it follows the left slope of Piusa valley until it reaches the motorway and railway line by Koidula railway station.
