The Cuevas de Waira (Waira Cave)

Lying in the top-list of the best caves in Argentina is the Cuevas de Waira, which are actually combined by two small caves named Cueva del Waira and Cueva del Aguirre. Waira is sometimes written Wayra. They are located high up on the mountainside above the town Tilcara. Tilcara lies in the Rio Grande Valley, on the Eastern side of the Andes range. It is accessible through Highway 9 from San Salvador de Jujuy. Because the Eastern slope of the Andes is under the rain shadow, it is quite dry and terrible weather is uncommon.

Quebrada de Humahuaca is the name of the mountain range to the west of the caverns. Tilcara is 2,460 meters above sea level, and the caves are about 2,900 meters. They are erosional caves created along a bedding plane in volcanic tufa. Approaching the cave would be a long hike uphill through arid hills and the ascent takes two to three hours, is often very exposed, even dangerous, and requires sure footedness. In fact, it requires physical fitness and stamina. On the other hand, you are rewarded with exceptional views
