We will set out from the parish of Odèn, where we can leave the car. We will go down along the forest road, after the steep slope and at the first bend we will look for the white and red paint marks of the GR1 that comes from Canalda and goes to Cambrils. Before us opens the head of the riuet de la Plana with views of the farmhouses of el Torrent and l’Oriola. We will follow the marks along a path and go down along the costa del Rosselló passing above the house of el Boix. We will continue going down diagonally along a wider path until we reach an asphalted forest road. We will cross the road and continue going down, along the old neighbour path, changing direction and leaving the GR1 marks.

The slope is steep and gradually becomes gentler; on the left-hand side, under a large outcrop above the farmhouse of la Plana, we will see the Balma de cal Rito.

We will continue going down, passing below the house of la Plana, zigzagging and approaching the head of the riuet de la Plana, normally dry in this spot. About five hundred metres further down, on the left, under a large rock, we will find the Espluga Cirer. Continuing downstream we will find the cova gran de l’Alzinera, the cova petita de l’Alzinera and the cova del Teixó.
