This could be a typical trek itinerary for the Santa Cruz trail. It may vary dependent on the tour operator.

Day 1:

Santa Cruz Trail

Most tour operator will start from Huaraz and go by bus to the small village of Cashapampa, the start of the trek. The first portion of the trek is at the bottom of a narrow, deep valley which soon opens up offering views of a mountain lake. After 6 hours you will reach Taullipampa, the camp site at 4400m, which is surrounded by a fantastic mountain scenery where you can see the peaks of Santa Cruz, Quitaraju, Artesonaju and Alpamayo.

Day 2:

Santa Cruz Trail

The trail ascends towards Punta Union, a pass at 4700m - not really fun for the mules here because the trail is rocky and sometimes slippery. From the pass you can enjoy panoramic views down the Santa Cruz Valley to the west and to the Huaripampa Valley to the east. From here it is a long and steady way down to about 3800m, the location of the camp.

Day 3:

Santa Cruz Trail

After descending a little further it is time to head skywards again. From here on the trek isn't all that great anymore because it follows the pass road. Most groups will camp just prior of the pass with good vistas of the surrounding mountain.

Day 4:

Santa Cruz Trail

Time for the next pass crossing today at 4750m. From the pass you have you have excellent views of the numerous road serpentines and Mt. Huascarán (6768m), Huandoy, Pisco and Chacraraju. You descent to the surreal blue mountain lakes ("Lake 69") into the valley below which is where you are picked up for your transportation back to Huaraz.
