By Jeep from La Paz towards the Milluni-Zonga dam until you reach the 'Casa Blanca' 4750m, 2h. Camping possible. 3km further there is a modern refugio.

The route is well marked with cairns and first crosses the glacier stream, then heads up a moraine later a scree slope to 'Las Piedras' camp at 5150m, 3h.

Usually the route is clearly visible from here from the constant stream of climbers. Head up the glacier to the left of a rock spur, then travers to the right. The trail steepens and turns left to the 'Campamento Argentino' at 5450m. Continue up the glacier, then a 50m 45° flank to reach La Pala. Continue to the foot of the summit east face and go staight up (150m, 45-50°) to the summit at 6088m.

The route is rated FR: AD; USA: AI 2.

As far as to the summit face , it's a technically easy walk on the glacier. Depending on the conditions (snow or ice), the summit face (45-50° at 150 vertical meters) is not an easy walk anymore.

But the main difficulty is acclimatisation. A couple of days in La Paz is certainly not sufficient! You also can't get acclimatised, by taking the 3 instead of the 2 day tour. If you are acclimatised, the climb can be done in 2 days without problems.

There are many agencies in La Paz, offering 2 or 3 day tours. They also provide you with the equipment. I booked my tour with 'Bolivian Journeys' (Calle Sagarmaya 363), which I can recommend. For the 2 days I paid 120US$ (with a maximum of 2 persons per guide) including equipment ( shoes, crampons, ice axe, harness, cloth if necessary), guide, food and transport.
