At 4750m, the mountain pass of Portachuelo de Huayhuash is one of the easiest passes on the entire circuit as it's ascent is so gradual.
The view here is taken from a hillock right above the pass - the pyramidal Trapecio(5644m) is right in front. To the left is the Puscanturpa(5442m). Behind to the right is the broad-peak of León Huacanan(5427m), Quesilojanca(5357m) and Yarupac(5685m).
It' s almost downhill all the way from here along the shore of Laguna Viconga before the next stop at a toll gate.
