Leave Poladura along the road. At the first bend to the left, the camino leaves the road to cross a small field. A brown mojón is visible from the road and marks the start of the mountain route. The first 1.3 km go uphill due northwest to an opening between two rocky outcroppings.
Another 300 m of visible paths and the trail turns left, continuing around the hill in a clockwise direction — downhill on your left, uphill on your right. It reaches a low point and begins climbing the next hill to the west. The trail turns south at around 2.3 km and shortly after takes a right turn, followed by another right 300 m on.
Another 500 m on the well-worn path comes to an end, but the camino continues straight, climbing steeply. You'll reach the high point at approximately 1,580 m altitude, about 4 km from Poladura. Markers for the next section are often obscured by ground cover or snow — be extra attentive.
Descend from here due north-northwest for 300 m. The path turns right and then splits. Do not continue straight and downhill. Turn left and begin another climb to a ridge. Follow the natural curve of the ridge for 600 m and turn left toward the ridge to your west. It's that ridge you'll follow into Arbas.
