Channel that is between the Echo of Nubiola and the Miranda of the Echoes.
Mandatory step to ascend to Miranda dels Ecos on its western side.
It consists of two distinct parts:
the upper part where the terrain is quite steep and the ground quite flat and with a good amount of loose stone between tree branches and bushes. Three sections of rope help a lot, whether you're going up or down. You have to be very careful because it is difficult not to drop a stone.
In the lower part we find a wall lock of about 12 meters equipped with a chain and depending on the time the occasional rope added. It is necessary to assess the ability of each person to overcome this section with strength of arms, both uphill and downhill.
Almost mandatory to wear a helmet if you go in a group, not to drop a stone is really difficult. It is recommended to bring a rope to secure those who have doubts or simply to rappel quietly.
