The Inca Trail in Peru stands as one of the world's most spectacular archaeological treasures, featuring ancient stone-paved pathways that wind through the breathtaking Andes mountains. This 15th-century network of roads, built by the mighty Inca Empire, served as the backdrop for Josh Gates' thrilling search for the legendary City of Gold on Expedition Unknown. Today, adventurous travelers can follow in the footsteps of both ancient civilizations and modern explorers along these sacred routes.
The Inca Trail is a network of ancient stone pathways built by the Inca Empire in the 15th century, winding through the Andes mountains of Peru and terminating at the iconic citadel of Machu Picchu. The trail consists of three overlapping routes—Mollepata, Classic, and One Day—with Mollepata being the longest and reaching the highest mountain pass before intersecting with the Classic route at Warmiwañusqa. The two longer routes require hikers to ascend beyond 4,200 metres (13,800 ft) above sea level, presenting risks of altitude sickness. Gates trekked this ancient stone-paved route through cloud forests and alpine tundra, passing Incan settlements, tunnels, and ruins, as part of his search for the legendary City of Gold—often identified with Paititi or other lost Incan refuges deep in the Peruvian Amazon.

Gates treks the Inca Trail in search of the City of Gold for Expedition Unknown
The Inca Trail is recognized by archaeologists as one of the most sophisticated examples of pre-Columbian road engineering in the Americas. Built primarily during the reign of Pachacuti in the mid-15th century, the trail network connected the far-flung territories of the Inca Empire, serving both logistical and ceremonial functions. The route to Machu Picchu specifically was likely used for royal pilgrimages and administrative travel, with the Sun Gate serving as a dramatic ceremonial entrance to the citadel. Mainstream scholarship holds that the trail was part of the much larger Qhapaq Ñan system—a road network stretching over 40,000 kilometers across the Andes.
The "City of Gold" that Gates investigated in the episode is more properly associated with legends of Paititi, a lost Incan refuge supposedly established deep in the Amazon after the Spanish conquest. While some explorers and fringe theorists have suggested that the Inca Trail could lead to undiscovered settlements in the cloud forests, no credible archaeological evidence has confirmed the existence of a major lost city along these routes. Archaeologists have documented numerous smaller Incan sites along the trail—including Wiñay Wayna and Phuyupatamarca—but nothing matching the scale of the mythical El Dorado or Paititi.
Gates' episode explored the tantalizing possibility that remote branches of the trail network could point toward undiscovered sites, consulting with experts familiar with Incan expansion into the Amazon fringe. However, the episode ultimately reflects the reality that much of the "City of Gold" legend is a blend of Incan oral tradition, Spanish colonial embellishment, and modern speculation. The Inca Trail itself remains an extraordinary archaeological achievement and a window into the logistical sophistication of the empire, even if it does not lead to a hidden metropolis filled with treasure.
For visitors today, the trail offers a remarkable journey through Incan history, passing stone staircases, agricultural terraces, and ceremonial structures that have survived five centuries. The experience Gates documented on camera—trekking through multiple ecological zones, from alpine passes to cloud forests—remains largely unchanged, though modern trekkers face permit restrictions and altitude challenges that Gates himself encountered during filming.
The trail passes through several distinct ecological zones, including cloud forest and alpine tundra, showcasing the environmental diversity of the Andes.
The highest point on the Classic Inca Trail is Warmiwañusqa ("Dead Woman's Pass"), reaching 4,215 meters (13,828 feet) above sea level.
The trail terminates at Inti Punku, the Sun Gate, which offers the first dramatic view of Machu Picchu for trekkers approaching from the trail.
The Inca Trail is part of the much larger Qhapaq Ñan road system, which stretched over 40,000 kilometers across the Inca Empire at its height.
The Inca Trail is accessible only through licensed tour operators, with permits required well in advance due to strict daily limits (approximately 500 permits per day, including guides and porters). The Classic route takes four days and three nights, while shorter options are available for those with limited time. Trekkers should be prepared for high-altitude conditions, with the highest pass exceeding 4,200 meters, and should allow time for acclimatization in Cusco before beginning the trek.

The dry season from May through September offers the best trekking conditions, with clearer skies and less rain, though this is also the busiest period. The trail closes each February for maintenance and restoration work.

Ecuador Cloud Forests
Ecuador's cloud forests share similar high-altitude ecosystems and pre-Columbian archaeological sites explored by Gates in his investigations of lost civilizations.
Mexico Mayan Sites
The Mayan sites of Mexico represent another sophisticated pre-Columbian civilization that built extensive stone cities and road networks, often investigated alongside Incan sites in Gates' episodes.
Colombian Jungle
The Colombian jungle has been the focus of multiple City of Gold investigations, as legends of El Dorado and Paititi often blur together in the search for lost South American treasure cities.
Best time to visit: The dry season from May to September offers the best weather conditions with clear skies and minimal rainfall for trekking the Inca Trail.
Travel tip: Book your Inca Trail permit well in advance as only 500 people per day are allowed on the classic trail, and permits often sell out months ahead of time.
