Exploring the Inca Trail is not only about reaching Machu Picchu, but also about experiencing one of the most diverse and beautiful natural corridors in the Andes, where every landscape tells a story of life, adaptation, and ancient heritage.

Fauna of the Inca Trail: Discover Andean Wildlife and Iconic Species While Hiking the Inca Trail to Machu Picchu
Spectacled Bear
The Spectacled Bear (Tremarctos ornatus), known locally as “Ukumari” in Quechua, is one of the most emblematic and fascinating species inhabiting the Machu Picchu Historical Sanctuary. It is the only bear native to South America, and its presence serves as a key indicator of the health of Andean ecosystems.

1. Distinctive Characteristics
This mammal is easily recognizable by the whitish or yellowish markings around its eyes; however, these markings are not always located there and often extend down to the neck and chest. These patterns are unique to each individual, functioning like a “fingerprint” that allows biologists to identify them. It is a medium-sized bear; males can weigh between 100 and 175 kg, while females are significantly smaller.
2. Habitat and Diet in Machu Picchu
The spectacled bear primarily inhabits cloud forests and puna zones (high-altitude grasslands). Although it belongs to the order of carnivores, its diet is 95% vegetarian.
- Behavior: They are excellent climbers thanks to their powerful claws, and it is common for them to build “platforms” in the treetops to rest or feed safely.
- Diet: It feeds on orchid bulbs, wild fruits, berries, and especially the tender parts of bromeliads (achupallas), which it often climbs to reach.



Andean Puma
The Andean Puma (Puma concolor), also known as the mountain lion or cougar, is the fiercest feline of the Andes and one of the top apex predators in South America. As a symbol of power and strength, this feline plays a crucial role in maintaining the ecological balance of the high-altitude ecosystems surrounding the Machu Picchu Historical Sanctuary.
1. Physical Adaptations and Characteristics
The Andean puma is a master of camouflage. Its thick coat ranges in color from silvery-grey to tawny gold and deep reddish-brown, allowing it to blend seamlessly into the rocky outcrops and golden grasslands of the Andes.
- Size and Agility: These muscular felines can weigh up to 75 kg and are famous for their jumping ability, capable of leaping up to 5 meters vertically.
- Solitary Nature: They are highly territorial and solitary animals, patrolling vast areas that can span hundreds of kilometers.

2. Habitat and Diet in the Machu Picchu Region
Pumas typically inhabit rocky slopes, high-altitude grasslands (puna), and the dense fringes of the cloud forest. In the remote mountain valleys of the Inca Trail, they find the perfect environment to hunt and rear their young.
- The Hunt: As opportunistic carnivores, they primarily feed on white-tailed deer and camelids (like wild vicuñas or domestic alpacas). In the lower forested regions, they may also hunt smaller mammals such as raccoons, coatis, and various rodents.
- Elusive Behavior: Although they live in the areas surrounding the famous ruins, encounters with humans are extremely rare. Pumas are “ghosts of the forest”; they are mostly nocturnal or crepuscular (active at dawn and dusk) and instinctively avoid human contact.
3. Symbolic Importance: The Trilogy of the Andes
In the Inca Cosmovision, the Puma held a position of immense spiritual importance. It represented the Kay Pacha (the world of the living, the Earth).
Spirit of the Warrior: The Puma symbolized the courage, freedom, and intelligence of the Inca people. Seeing signs of a puma near a sacred site was often interpreted as a powerful omen of protection
The Shape of Cusco: Ancient chronicles and archaeological studies suggest that the city of Cusco was originally designed and built in the shape of a Puma, with the fortress of Sacsayhuaman representing its head.
