This is the shortest route to the summit but it's possible to climb also Rallón in the same day parking the car between both peaks.
Getting ThereSee the main page to approach to Arguedas and Bardenas.
For the access to Cabaña de Piskerra you have two forest track. The best option is the dirt track of Los Cambrones but you have another good option in the track to Carcastillo (Pista del Caldero) after 200m.
We begin in the track near of small hut of Piskerra (it’s very advisable the use of a map to identificate the place). We walk to the hut following the track. In the hut we walk to left (N.W.) to reach the entry of the labyrinth. You have two options from this point:
A)-We follow to left bordering the small hills of sand to reach the back of the peak following a confuse area with small ravines (it's very important to follow cairns). You must climb the N.W. face among small plants searching a little path that reach the col between both summits. The left summit is the highest.
B)-We can search a route of adventure entering in right side to the labyrinth of Piskerra climbing small ravines under a small hut in the top of the hill in right side. We reach the exit in a col at S.E. of the peak. We walk in direction to the space between both summits climbing across a path to the upper plain.
