Andean Crossing 10 ´days

The horseback riding "Crossing the Andes Mountain Range", starts and finishes in Mendoza - Argentina. The expedition arrives until the international border between Argentina and Chile and comes back on horses for the argentinian side. We will ride through the Aconcagua region up to the Chilean border. Here stands the most massive and immense mountains in America, including its tallest peak, the Aconcagua (23,000 ft). Riding at heights over 4000 meters. (13,100 ft). It is in these uninhabited places, which you can only reach on horseback, where huge herds of guanacos roam freely and the Andean condor nests. Only in unique places like this can you enjoy watching them in plenitude.

This is also a place where history was written. In 1817, the Los Andes Army, led by San Martin (Gral. Liberator) crossed through this exact same spot on their way to liberate Argentina, Chile and later Peru from the Spanish Conquistadors. The setting offers a glimpse of the efforts our Fathers of Independence had to overcome. As the sun sets, the spectacular stars of the southern hemisphere will cover the sky. Relax at the camp with its peaceful atmosphere. The campfire lightens up the darkness as you share a cup of coffee or tea. All this creates the ideal ambiance to feel the timeless spirit of nature and make new friends.

You don't need to be a superb athlete, but you do need to be in a good health condition, so that you can enjoy a 10-days expedition in direct contact with nature, far away from daily comfort or commodities (For example: It is necessary to mount and get off a horse many times a day, sleep in tents etc.). The land we will cross has varied terrain such as crossing of rivers, ascents and descents on narrow and steep paths. This is not difficult for the horses, as theses mountain horses are used to the climbs.
