Trekking in the Sierra de los Comechingones - Pueblo Escondido


An oasis in the Central Hills ...

Walk around Merlo, San Luis, always an invitation to the pleasure of trekking. Ascend the abrupt slopes of the Sierra de los Comechingones, which divides San Luis and Cordoba provinces and the same as, a little further north, home to the mythical Cerro Champaquí. Reaching the small and imperceptible summit of Cerro de las Ovejas, the highest in the Puntana province. Transit through the plains of the mountains, at 2000 meters above sea level and it gets lost to the old town of "Pueblo Escondido".

Schedule (trekking): 3 days of adventure, with backpack and camping in the middle of the mountains, invite illusion.

Day 1: Meeting in Merlo, San Luis. We move by charter vehicle to the top of the mountains, after having made the last purchases. Preparation of equipment and we go for a walk in the first stage. We move north along a large track and then off the trail to climb to the highest peak in  San Luis province, the Cerro de las Ovejas, at more than 2200 meters above sea level. Lunch on the way. We will continue with the trekking to reach a mountain post, where we`ll make the first camp. Dinner and overnight.

Day 2: Breakfast. This day, the trekking will take us to Pueblo Escondido, a group of buildings that housed miners from the 20th century when the work with Tungsten (for the lamps) was relevant. Lunch on the way. Upon arrival, we`ll look for an appropriate place to set up the camp (dormis option). Snack and free to enjoy the place. Dinner and overnight.

Day 3: Breakfast. Disarmed the camp. The path now, ascending, will take us to the summit of Cerro Aspero, a great viewpoint of the place and from there we`ll go to the great Salto del Tigre, a waterfall of more than 50 meters. We`ll stay there to enjoy the place. Lunch. We continue with the walk to the upper path of the mountains, where a vehicle will look for us to be able to descend to Merlo and to the bus station. End of the program.

Is it a program for beginners in trekking and camping?

Yes, because it has hikes without much unevenness. In any case, it must be understood that these are camping tours in isolated places.

You can only sleep in a tent?

There is the possibility of hiring dorms on the second night (bunk beds, in a shared room), extra cost.

Difficulty graduation

Mochila: Peso / Duración de la Jornada.

Exigencia Física

Técnico: Dificultad en el Terreno / Equipo.

Fortaleza Psicológica

Exposición a la Altura

Backpack (M)

This point has to do with the weight that we must carry in our backpacks. Trekkings or crossings where we have pack animals allow us to bear less weight on our backs. And the multi-day journeys in Patagonia (without the option of having pack mules) generally make us carry more weight, especially in the early days.

20% Up to 5 Kilos: Short excursion walks / Trekking Talampaya

40% Up to 8/10 Kilos: Round-trip trekking / Vallecitos 3 and 4-day programs

60% Up to 12/15 kilos: Crossing trekking with porting / Crossing of the Andes Paso Portillo

80% More than 15/18 kilos: Cross-country trekkings with little or no portage / Trekkings in Patagonia (Paso Vuriloche, PN Lanin or Nahuel Huapi, etc)

100% More than 25 Kilos: With a lot of equipment on top and little or no porting / Continental Ice

Physical (F)

We consider physical demands to the wear that we can suffer both aerobic (climbs = possible shortness of breath) and muscle (resistance = many hours walking) and of legs and joints (descents = knees / ankles).

20% half a day or less with little unevenness.

40% more sustained slopes and longer days in the activity. 2-3 days / more than 6 hours per day.

60% Long ascents and descents with a longer duration. Ascents to more than 4000 meters in the central mountain range / intense 4-day trekking (Uruguayan plane)

80% Important work of legs in resistance. Very long days. Very long day ascents (Lanin - Domuyo) or more than 5000 meters. Ice courses.

100% Maximum demand. Aerobic work and constant effort on legs. Continental Ice, Aconcagua, mountains of more than 6000 meters.

Technical (T)

The technical difficulty is mainly based on the terrain. How much can it cost us to climb a slope, if it is very steep or if we have to use our hands in some section (simple climbing), both in rock and snow-ice, or materials such as crampons and pegs in other ascents.

20% flat land

40% trails with moderate ups and downs. General crossing trekkings . Sierra de la Ventana, Córdoba, Patagonia, Cuyo, north, others. Classic ascents

60% Steeper slopes and trails. Possible use of crampons. Domuyo, Cordón del Plata, Cordillera Central.

80% Mixed terrain, with snow or ice. Alvear, Lanin, Tronador. Bolivia, Peru.

100% Highly technical terrain. Glacial transit and climbing in sections. Hill climbing with sections on slopes of more than 60 ° inclination

Psycho (P)

We maintain that this point, the psychological factor, represents a relevant factor. Each one needs a factor of conviction, confidence, self-control and will power to achieve a goal. And depending on the attitude with which we face distances, slopes, terrain and many other objective factors, we can achieve performance with very different results.

20% We will not be much affected.

40% This is a normal level of attention.

60% We require more motivation, enthusiasm and concentration.

80% The activity will require us to be very connected and convinced.

100% Maximum control and emotional-psychological performance.

Adventures (A)

It is the factor that, the height above sea level, influences us depending on the activity we carry out. Managing and overcoming symptoms caused by altitude is the key to this point

0% + sea level.

20% Up to 2000 masl.

40% + 2000 masl.

60% + 4000 masl.

80% + 5000 masl.

100% + 6000 masl.
