ENG:Glaciar Nieves Negras
This trek is found in the heart of the Andes. After a steep incline towards a spectacular glacier, one can basque in hot springs on the way down (or one the way too if you’re an enthusiast).
Best time to visit
- Hiking: Between February and the start of May, when the vehicular road closes for the first snowfalls. Between October and January, the River Azufre has a heavy flow and is nearly impossible to cross. For those more cautious, the best time to go is March or April, when the river is calmer.
- Randonnée: End of May or early June to September.
Access to Baños Colina
From the intersection at las Vizcachas (Avenida Camilo Enríquez and Avenida Eyzaguirre, km 0), take the road G-25 towards Cajón del Maipo, and follow it until km 65.1 (asphalt ends in the km 66.3 just before Lo Valdés) where there is a bifurcation. To the left, it leads to Baños Morales along a dirt road, located on the other side of the El Volcán river. Between June and September this road might be closed if there have been recent snowstorms. You can check the road status with Carabineros at San Gabriel (+56228611008 y +56228612290) although their answers tend to be on the conservative side. This will be the last place to stock up. Continue along the main road passing the sign for Baños Morales, then 1.5 km after the fork you will pass by the mining town Lo Valdés. Six kilometres after this, passing Cuesta de los Afligidos, you will go over a bridge crossing the River Colina. 5.5 km further, by dirt road, you’ll arive at the entrance gate to the hot springs (Las Termas de Colina)- 77.1 km.

Outline of the route
From the station located 660m to the East of Baños Colina (km 0, 2540m), follow the path that goes up the River Colina towards the hill Puntiagudo, along the North Eastern bank of the river. After 15-20 minutes from Baños Colina, you reach a bridge crossing the River Colina towards its South Eastern bank (km 0,7 - 2520m). Then, you must follow the South Eastern bank, in an area in which the valley is narrow. You will cross various little slopes, until reaching a wider zone with the ravine Estero los Caballos (km 2,1 - 2590m, ½h till this point). Immediately after this estuary, you find a meadow, often home to animals. Here, you are at the base of the hill Puntiagudo. To the side, it is possible to see a mining road. Continue towards the East through a bushy flatland. The track goes close to the cliff’s edge but remains rather clear in this part of the trek.
3.7km in (2650m), you go down a little to reach another meadow, located at the edge of the river; a pleasant place to quench your thirst. After this, finding the path is harder. The important thing is to get close: look for the closest area to the River Colina. If you get lost, simply continue going up the valley.
Note the large fossil 4.45km in in the middle of the hill.
4.8km in (2680m), the path goes down to cross the River Azufre, a little further up at its joining with the river that comes from the glacier Nieves Negras, you find Estero Blanco (the meeting of these two estuaries forms the River Colina). Crossing the River Río Azufre shouldn’t be too difficult but for safety reasons you will need to take off your shoes and get your feet cold. After crossing the river there is an open field, which you must cross carefully (it is quite muddy). Once the field is behind you, the track curves to the North towards the Southern face of the volcano, San José.
The path continues in a clear direction to the North, with the glacier Nieves Negras in the background. To the right, you will be able to see the outline of the hills Amarillo, Panamericano and Manu Tara. 7.6km in (2945m), you arrive at the estuary Blanco, that is quite fast-flowing and steep. Considering the estuary come from the valley Paso Nieves Negras.
There are many fields in the surrounding area that can get your feet damp if you’re not wearing appropriate footwear. Keep going northwards through a sloped area. In the area surrounding the glacier, the footpath disappears. It is highly recommended to continue to get a good view from what is marked as a viewpoint on the map; a pyramid shaped hill of dark rock.
The area right before the front of the ice is very steep, loose and very exposed. Hence, ascend the east slope about 100 meters before the beginning of the ice. Then head north along higher ground, far from the steep cliff. This section is quite uncomfortable and exposed anyway.
Then go down to the actual glacier and keep walking over it. There is no risk of falling into a crevasse or of dangerous slips as it is completely covered by debris. After about 20 minutes hiking over the dirty section of the glacier you will reach the aforementioned pyramid shaped hill of dark rock. At last, you will get a totally clear view of the massif. At 3220m, you will have 2500 vertical meters of ice in front of you.
- Trekking: Consider 3,5 hours to the base of the glacier and an extra half an hour to reach the viewpoint at the dark pyramid.
- Randonnée: Two days and a half, as you will have to ski the stretch Lo Valdés - Termas de Colina.
