Megalithic Basalt Tombs Overlooking a Tranquil Andean Lagoon. Perched on a windy peninsula jutting into the sapphire waters of Lake Umayo, Sillustani features dozens of colossal stone funerary towers called chullpas. Built by the fierce pre-Inca Colla kingdom and later perfected by Inca stonemasons, these tombs reach up to 12 meters (39 feet) in height and held the mummies of entire royal families.
Historical Significance & Archaeological Clues
The architecture of Sillustani represents some of the most sophisticated stonework in pre-Columbian America. Colla nobles were mummified in the fetal position and placed inside with gold offerings, dried food, and pottery, oriented eastward toward the rising sun to symbolize rebirth.

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:
-
Towers are wider at the top than at the base, creating a distinct inverted cylinder profile. -
Inca builders used massive curved basalt blocks joined with millimeter precision. -
The island in Lake Umayo is a protected reserve for wild vicuñas. -
Burial openings face strictly east toward sunrise and the underworld.
Practical Tips & Recommended Gear
If you are flying out of Juliaca (JUL) airport back to Lima, book a private transfer from Puno that includes a 2-hour stopover at Sillustani. It breaks up the drive perfectly and avoids a separate excursion.
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.
