Day 3

Pisaq Exploration

Your journey continues on a mountaintop in the Sacred Valley with a visit to the village of Viacha, followed by a downhill hike to the Pisaq archaeological site. Comprised of fascinating ceremonial, agricultural, and residential architectural components as well as evidence of the Inca’s scientific research practices, it is one of the most comprehensive sites in the region and will give you true insight into their ‘cycle of life’ philosophies, especially those that connect man with nature. / Morning visit to the village of Viacha / Downhill hike from Viacha to explore the Pisaq archaeological site / Optional drive and visit to the town of Pisaq / Scenic drive to Lamay Lodge / Traditional Pachamanca late lunch at the lodge and afternoon at leisure / Early evening lecture before dinner: Ancient Cusco and the Bohic Ruz Explorations—the Symbology and Intentions Behind the Design of Ancient Cusco and Alignment of the Sacred Temples on the Planetary Axisread more

Day 4

The Qapaq Nan and the entrance to the Paititi - the City of Gold

Begin your day exploring Ancasmarca in the Calca region, once the most important grainery and storage site for food and other goods on the Antisuyu Trail from Cusco to the jungle, followed by a scenic drive to the Lares town of Choquecancha for lunch alongside members of this remote Andean community. Afterwards, embark on a thrilling hike that follows the footsteps of the Incas along part of the original ‘Qapaq Ñan’ (Inca trail network), also known as the ‘Road to Paititi’, or ‘El Dorado’, the legendary lost ‘city of gold’. / Morning drive to Ancasmarca / Guided exploration of the Ancasmarca archaeological site / Lunch in Choquecancha / Optional afternoon hike from the trailhead in Choquecancha to Jaukaniread more

Day 5

Connecting with the Apus

As significant as the stars were to Inca culture and mythology, so too was their connection to the ‘apus’, or earth gods, especially Pachamama (Mother Earth). Revered for her role in providing life and abundance, the Incas often dedicated ceremonies to Pachamama in gratitude and hope for her continued grace. Today you will have the opportunity to participate in a traditional Pachamama ceremony alongside members of the remote Marcacocha community, followed by visits to two significant archaeological sites during your journey back to the Sacred Valley. In preparation for Day 6, enjoy an evening lecture on the architectural design of Ollantaytambo and its importance as a ‘cog in the Inca constellation wheel’. / Scenic morning drive to Marcacocha through the highland lagoon region surrounded by breathtaking mountain peaks / Pachamama ceremony in Marcacocha / Drive to the pre-Inca Pumamarka archaeological site for lunch and guided exploration / Continue on to Ollantaytambo in the Sacred Valley for an optional visit to Quellorakay, an original royal Inca residence / Evening lecture at hotel: The Archaeoastronomical Design of Ollantaytambo and Pakaritampu / Dinner at hotelread more

Day 6

The Equinox - Pakaritampu Pyramid & Ollantaytambo

The pyramid of Pakaritampu is arguably the most significant Inca structure related to the equinoxes and solstices. In Cusco, it is believed that the ancient sundial precedes Inca culture by thousands of years, which would confirm the theory that the Incas were the final link in the archaeoastronomical heritage of the region. Today you will witness the effect of the equinox sunrise over the pyramid, followed by an exploration of the fascinating and enigmatic structures of the Ollantaytambo archaeological compound. / Uphill hike at dawn to explore the Pakaritampu Pyramid, followed by a comprehensive tour of the Ollantaytambo fortress / Lunch in the town of Ollantaytambo, the oldest ‘living city’ in South America / Afternoon train to Aguas Calientes at the base of Machu Picchu / Early evening lecture: Machu Picchu—Unravel the Secrets of this Mysterious Citadel / Dinner at hotelread more

Day 7

Machu Picchu

Your archaeoastronomy journey culminates today with an exploration of Machu Picchu. Similar to Pisaq, the citadel is divided into multiple ceremonial, residential, and agricultural areas. Scientifically, however, this mysterious site was much like an institute of higher learning, dedicated to the study of astronomy, architecture, engineering, hydraulics, and more. During your visit you will delve further into its history, purpose, and subsequent discovery after hundreds of years, hidden high above the Urubamba River and covered by the lush foliage of the cloud forest that borders the Amazon Jungle. More importantly, though, you will discover why this ‘jewel of the Inca Empire’ is the basis for the Andean people’s profound connection to the cosmos. / Early morning shuttle bus to Machu Picchu (approximately 20 minutes) / Hike to the Sun Gate and visit to the Inca Bridge / Lunch at Sanctuary Lodge / Guided exploration of the citadel / Afternoon train ride to Ollantaytambo followed by a scenic sunset drive back to Cusco.read more
