After crossing the Andes a first time during my way from Santiago to Mendoza, I decided to come back to the Andes. At an altitude of 3000 meters, a trek starts to the first base camp on the way to the Aconcagua. Aconcagua is the highest mountain in South America with 6 962 meters high.

A tour around the lake

After entering the park, you arrive in a small area with a beautiful lake. TheĀ unforgettable blue-greenĀ color reminded me the beauty of Patagonia nature. The loop, around it, is about 40 minutes.

The Trek to Confluencia

If you are looking for more adventure, you probably have to continue to the first base camp. The base camp located 8 kms further on and surrounded by gorgeous landscapes.

For going further the bridge on this trek, you need to pay a more expensive entrance. Control are done at the entrance and at the base camp.

I spent the day with an American I met in my hostel. With a good condition, he was pushing us forward. We did the 8kms in 2 hours. During the steepest part of the trek, I remembered suddenly that I was at an altitude of 3kms. Oxygen was missing and I was breathing like if I was running.

Fortunately, the weather was especially gorgeous a blue sky and a splendid sun. During all the morning, the Aconcagua peak was completely clear.

Once we arrived at the base camp, we went to the guard office to register. At the base camp, you have a toilet and a point of water. Next, we continued on a small hill close the camp. The top of this hill is the perfect point for enjoying the landscapes around you. Meanwhile, we ate our sandwiches there.

The final view surrounded you on the top of a small hill close to the camp is worth doing the trip. However, you haven’t a good view on the Aconcagua from the base camp. So, I recommend you to enjoy the view before!

After 1 hour at the camp, we went back with new friends met during lunch. As we were speaking more, we surprisingly did the return in a longer time: 2h20.

At the beginning, we planned to go back to the city close to the park Entrance. It is possible to follow train tracks that lead to the town while crossing the Inca bridge. A natural bridge that is a classical tourist attraction. From the town, the bus leaves a bit later 16h55.
