Peru – The Lost City Of Gold’: For 500 years, the “Holy Grail” of the Incan Empire has remained hidden. While Spanish Invaders stripped Peru of its gold, one sacred object vanished before they could grasp it: The Great Golden Disc of the Sun. We follow explorer David Adams and archaeologist Gary Ziegler deep into the “Forbidden Zone” of the Vilcabamba cloud forest. This isn’t just a trek—it’s a high-stakes hunt for the rebel fortresses and secret temples that stayed invisible to the Conquistadors.
