Paso de Aguas Negras, San Juan

#3 of 6 in Scenic Drive in Cuyo
The Agua Negra Pass is a pass over the Andes mountains which connects Argentina and Chile. The highest point of this pass is at 4780m AMSL.Agua Negra TunnelTo improve trade between Chile and Argentina, a 14 km, three-bore vehicular tunnel below the pass is planned, which will allow year-round traffic. In March 2015, Argentina officially approved the project. It is awaiting ratification from Chile.Also planned for the deepest part of the tunnel is the Agua Negra Deep Experiment Site : an underground laboratory. Because all currently operating deep underground laboratories are located in the Northern Hemisphere, a Southern Hemisphere site would have some unique benefits: Combined with existing neutrino detectors, a longer baseline would allow more accurate localization of sources in neutrino astronomy, and When searching for dark matter, there is expected to be a seasonal variation due to the Earth's motion around the Sun. But such a signal could also be an error, caused by some subtle seasonal effect. Confirmation from a location with opposite seasons would rule out such an error.

  • We crossed the day 21 January 2018, in a van, nafta partner. from Argentina to chile. We left flowers at 7 am, the road was very well and almost didn't traffic in all of the cruze, the gps set it in flowers and I put the phone in airplane mode, the gps system continues to operate without a problem, with the partner did not have any problem with c amino, after arriving in the 4700 meter descent toward chile was wonderful, you should go slowly and playing Horn in curves that many large trucks bend as if they were in the dakar. Once we arrived in chile, we slept in vicuña, beautiful people to rest after the cruze. CLOSE ATTENTION TO LAWS OF TRANSIT CHILEAN, MUST STOP AT THE POSTERS THAT SAYS STOP EVEN IF THEY DO NOT COME CARS OF THE SIDES AND ATTENTION TO THE PEDESTRIAN PATHS THAT ARE A HALF BLOCK, PEDESTRIANS CAN CROSS WHEN THE DESIRED, MUST BE VIGILANT TO THESE RULES. SUPER RECOMMENDED AND WONDERFUL EXPERIENCE WITH MY FRIEND PAQUITO. Recommendations: - bring water and fruit - ensure the naphtha in flowers ypf station, then there is no more. -do not use air conditioning - if lower the auto in the high mountains make it all slow because the apune is strong - when they arrive at the chile border post make you throw all the food not embazados (yerba mate step and also cookies)-caution with the C AMIONETAS COMING FRONT IS PREFERABLE TO WAITING FOR IT TO PASS, DO NOT RESPECT SPEED OR PRIORITY

  • Very cute and quaint way. There are 80 km of gravel with cornice road. Take it easy and enjoy the scenery. It is passed without problem, even cars. Pay attention with the cars coming from front, since not all drivers dominate driving in this type of roads, and can last entering the curves and make you have a bad moment. There are 2850 meters above sea level. Drink water and avoid stirring. If you're Argentinian, tomato with calm the Transact customs, says everything you bring, since past few cars that way, take all time to check and see if you bring something non-declared. Enjoy it! Few roads in the Argentina are so like this.

  • Its a must for motorbike pass....
  • Sensational cross that Paso, but consider the following:-never spend the night, because the customs are not 24:00; -Reserve at least 5 hours to cross 250 km with caution and enjoying the journey; -Before starting check the spare (4 wheels) or has means to fix your wheel (motorcycles), because we saw several vehicles with penis stuck or pieces of abandoned tires on the side of the road; -Have a hand wrap (4 wheels) so I could get out and take some pictures, or use extreme cold clothing (2 wheels) to cross the Paso. Other than that, enjoy the crossing which will provide you with a unique experience. 🔝🔝🔝👌🏻

  • The landscape is cute but it's hard for a car... and despite having van have to tread carefully... Because wheels are broken and crash.

  • 100 points. The weather had prevented us from making the crossing several times, but persistence had his prize: worth every metre that is made. Some people may be affected by the height, since you can reach almost 4800 metres
