Laguna Blanca is an elusive peak in the Catamarca region of Argentina. Until GPS mapping showed that Laguna Blanca was a 6,000er, albeit only just – at 6,012m it is the second lowest 6,000er in the Andes - this peak was largely ignored by hikers and mountaineers. It is easy to understand why, as this is little more than a big lump of scree hidden behind lesser peaks in a remote and little visited corner of NW Argentina. Cerro Laguna Blanca is named after the lake Laguna Blanca which sits at its foot to the southeast.

The lake and mountain are part of the Reserva Laguna Blanca, a regional park with one of the highest population densities of vicuñas in the world. Despite its remoteness it is possible to reach the trailhead by public transport and climb the peak supported in 1-2 days or unsupported in 2-3 days. According to the mountaineering museum in Fiambala, the first ascent of Cerro Laguna Blanca was in late 2006, and it has probably received fewer than 10 subsequent ascents.

Getting There

Catamarca is the nearest major city and has regular connections by plane and bus from Buenos Aires. From Catamarca there are 2 or 3 buses per week to Antofagasta de la Sierra that stop at El Peñon on the way. El Peñon (altitude 3,400m) is the village closest to the trailhead. El Peñon has 2 accommodation options (a relatively pricey hosteria and a pension with a very helpful owner), a few shops and a police station. It is possible to buy basic supplies such as tinned food and crackers in El Peñon. From El Peñon to the base of the mountain there are three options:

Cycling towards Laguna BlancaThe green oasis on the left of this picture is El Penon. Laguna Blanca is behind the ridge and directly above the rider's head.
1) A jeep can be hired in El Peñon to drive you to about 4300m on the western side of the mountain, where the river starts to flow in a quebrada. You could then arrange to be collected in a day or two from the same place. You may wish to arrange this jeep in advance from Catamarca. It would be possible to summit in one day if you left El Peñon very early and you were very strong, acclimatised and fit. Most people should aim to reach high camp in a short day from the drop off point and then summit and return to the drop off point in a further (long) day.

Quebrada on the approach to Laguna BlancaThis Quebrada leads all the way from 4,300m to 5,600m and the final climb to the summit.
2) Hitch (there isn’t much traffic) or walk back south from El Peñon along the main road for 10km to a tiny concrete bridge crossing a dry river bed (at 3,550m). Or jump off the bus at this point on your way from Catamarca to El Peñon. Follow this dry river across an open and shelterless plain until it becomes a quebrada in which (when we were there in December 2010) the stream began to flow at about 4,300m. This is near the drop off/pick up point mentioned in 1) above. This part of the walk takes at least 3 hours so make sure you are carrying enough water.

3) Walk straight from El Peñon to the drop off point where the quebrada emerges from the mountains at 4,300m near the drop off point. This would be an exceedingly boring, and in summer hot, first day crossing a flat plain with no water.

The Route

The summit Laguna BlancaWhich one is the summit?
From the drop off point stay in the main quebrada following the bubbling stream as it initially heads south east before turning east. The water stops flowing at about 5,000m where you can set up your high camp in an open basin. Keep following the valley as it heads north all the way to 5,600m from where you can scramble up the scree to the summit plateau.

Summit of Laguna BlancaMaybe this one?
Once on the summit plateau, it is slightly confusing as to where the highest point on Laguna Blanca is. There are three tops of near equal height, but as they are quite close together we visited all three and the central summit showed the highest altitude on our GPS. The northern of the summits in the table below may well be slightly higher however.

Alternative Route

It is also possible to climb Laguna Blanca from the village of Laguna Blanca in 2 to 3 days. If anyone has any information on this route please contact me so I can add the information to this post.

Red Tape

There are no permits needed for this peak, however it is wise to inform the local authorities in El Peñon of where you are going and when you expect to be back.

When to Climb

The warmest period is between December and March however this climb can be carried out at anytime of year. Crampons and ice axes will probably be necessary during the winter months and a bit of snow on the mountain would make the climb more interesting and worthwhile, as without snow this becomes a trudge up a big rocky mound of a mountain which is at times rather dull.


There are many places to camp along the route and we found water flowing in the quebrada between 4,300m and 5,000m. Above this there are a few penitentes fields from which it is possible to collect ice. Make sure you have a strong tent because there are sometimes crazily strong winds in this area.
