This cascade of the river coming up from the trees is an example of yet another one of the spectacular corners one can find in the area.
Many routes cross this way and it is perfectly fenced off, so it can be visited without difficulties although it is well worth it to approach the closer boulders to perceive its power and roar.
It can´t be said that this area has waterfalls but rather cascades and it is not in Viella but rather in Val d´Arán, in the direction of France, I don´t know which village it belongs to.
In winter I suppose it is not possible to reach this place, but it must be beautiful to see it covered in snow. If you can, I recommend you to visit these valleys.
