Andes Mountains

The basics

Mendoza—Argentina’s main wine growing region—doubles as a gateway to the Andes Mountains. As well as including plenty of wine tasting, day trips to Mendoza typically visit a lookout point with views of Mt. Aconcagua. The 22,841-foot (6,962-meter) mountain is a favorite among mountain climbers, but it’s an intensive trip that requires planning, training and high-mountain gear. Most visitors content themselves with admiring the mountains rather than climbing them.

Other day trip options include horseback riding in the foothills of the Andes, trekking to the summit of Lomas Blancas, or spending a day relaxing in some regional hot springs.

Things to know before you go

• Remember to dress in layers, as temperatures can vary greatly at different altitudes.
• Wear sturdy shoes suitable for walking over uneven surfaces, even if you don’t intend to trek.
• The sun can be intense at high altitude, so bring plenty of sunscreen, as well as sunglasses and a hat.

How to get there

The Andes Mountains lie to the west of Mendoza and are best visited as part of an organized tour with round-trip transportation. It’s also possible to drive across the Andes Mountains between Argentina and Chile via the Paso Internacional Los Libertadores.

When to get there

The best time to visit the Andes is between October and April. Climbing season runs from mid-November to the end of March, but the mountains are at their busiest in December and January.

Wildlife in the Andes

Though parts of the Andes may look barren, the mountains are home to abundant wildlife such as guanacos, slim-necked relatives of the llama whose wool is highly prized. It’s also fairly common to see Andean condors—whose wingspan measures up to 10 feet (3 meters)—coasting on thermal updrafts. As you’re hiking or horseback riding through the region, keep an eye out for chinchillas, alpaca, taruca and huemul deer, and South American foxes.
