Cueva de los Tayos de Coangos, meaning Cave of the Oilbirds in Spanish, lies in high rainforest around 539m above sea level and includes over 4 km of passageways and shafts, including a chamber that is 90 meters by 240 meters.
The local Shaur Indians have used the caves as a source of fledgling tayos for many years, but it’s not these little birds that have drawn other adventurers.
Rumors of gold and other treasures have lured many people and expeditions to the cave complex. Erich von Däniken wrote in his 1973 book The Gold of the Gods that back in the 1960s János Juan Móricz had explored the cave and found gold. He also claimed to have found a strange metallic library with strange plates that some have claimed could not have been made by humans without help.
