Description

Puente del Diablo (Devils Bridge) is a river cave with many speleothems and several karstfenster which is visited on cave trekking tours. They are not as demanding as canyoning tours, there is almost no climbing, but they are done wading in knee high water most of the time. The cave is located about 3 km south of La Poma at the Rio Calchaquí. The valley is located in the Andes and La Poma is more than 3,000 m above sea level. As far as we understand there are differen guides/operators, so check the tourist office at La Poma for a guide. Most likely the trip from town to the cave is included.

The formation of the karst caves is a result of volcanism, which is quite unique. Nearby twin volcanoes Los Gemelos erupted and a lava flow covered the valley of Rio Calchaquí. The water was dammed, but is formed its own escape route under the basaltic lava flow in the soluble limestone. The result is a karst cave with erosional history covered by basalt.

The exceptional cave, though not far from the town, is located in the gorge and hard to reach. It was known to the native people since ancient times, they used it as a natural bridge to cross cattle. But they never entered the cave, as the beliefs and legends tell that the Devil lives inside. So it was first explored only 20 years ago, in 1999, by Luis Carabelli, from Argentine Federation of Speleology (FADE). In 2000 he presented the discovery on the Argentine Congress of Speleology. Further research in the area revealed many other caves and finally the Argentine Federation of Speleology (FADE) organized a course on water cave exploration in 2009. Several locals were participants and are now very competent cave guides offering cave trekking tours.
