The Subterranean Masterpiece Carved into the Granite Abyss. On the sheer northern face of Huayna Picchu mountain, 400 meters below the summit, lies the Temple of the Moon (Templo de la Luna) — also known as the Great Cavern. Unlike the exposed ruins on the ridge, this temple is nestled within a massive natural granite cave with stone masonry so refined it matches the finest imperial stonework of Cusco.
Historical Significance & Archaeological Clues
The cave features double-jamb trapezoidal doorways, carved niches for sacred mummies, and a ceremonial stone throne. It is believed to have been a sacred cave dedicated to Pachamama (Mother Earth) and ancestral veneration, deliberately hidden from plain view.

Lesser-Known Secrets & What Most Travelers Miss
While standard travel guidebooks focus on superficial highlights, seasoned Andean trekkers and resident specialists know that the true magic lies in the details:
-
The masonry features millimeter-tight joints without any mortar. -
A natural aperture in the rock admits moonlight during specific lunar cycles. -
The path descends the 'Stairs of Death', an exposed flight of cantilevered granite steps. -
Rare native orchids (Epidendrum secundum) cling to the cave entrance walls.
Practical Tips & Recommended Gear
Sturdy trekking shoes with ankle support are essential. Keep your hands free by packing your gear into a small daypack. Use the steel safety cables installed along the sheer cliff edges.
Essential Traveler Advice
Always carry small-denomination Peruvian Soles notes (10, 20 and 50 bills). Remote community checkpoints, pack-mule handlers, and artisanal weavers cannot make change for large 100 Soles bills or accept foreign credit cards.
