Lago Chungará is one of the most spectacular natural wonders of northern Chile—a high-altitude lake surrounded by snow-capped volcanoes, protected wildlife, and ancient Andean culture. Located at over 4,500 meters above sea level, this pristine lake sits within the Lauca National Park in the Arica y Parinacota region, making it not only one of the highest lakes in the world but also one of the most biologically diverse high-Andean ecosystems. This comprehensive guide explores everything travelers, researchers, and nature enthusiasts need to know about Lago Chungará, including its formation, wildlife, cultural heritage, travel advice, and scientific significance.
Situated along the Chile–Bolivia border, Lago Chungará is an extraordinary example of a high-altitude volcanic basin. Formed by geological processes related to the nearby Parinacota Volcano, the lake covers approximately 21 square kilometers and is fed by glacial melt, underground springs, and seasonal rains. Because of its extreme altitude, the climate around Lago Chungará is characterized by cold temperatures, strong UV radiation, and dramatic day-night thermal swings. Despite this, the region supports a rich array of life—from flamingos and vicuñas to rare aquatic plants adapted to oxygen-poor waters.

The lake’s calm waters reflect the towering Volcán Parinacota, creating some of the most iconic landscapes in the Chilean Altiplano. The harmony between lake, volcano, and high-Andean plains forms a hotspot for ecological research, photography, and eco-tourism.
Despite harsh conditions, the environment around Lago Chungará is a thriving sanctuary for dozens of high-altitude species. The lake and its surrounding wetlands (bofedales) are designated as protected areas under the UNESCO Biosphere Reserve program. The high mineral content of the lake supports algae and microorganisms that form the foundation of the food chain, attracting flocks of flamingos, Andean gulls, and various migratory birds.
Researchers studying climate change frequently visit the Lago Chungará ecosystem because it serves as a natural laboratory. At this elevation, even small temperature variations significantly affect water chemistry, migratory patterns, and plant growth. Recent studies have shown that warmer seasonal temperatures are shortening the ice-cover duration on the lake, potentially altering habitats for endemic species. These findings make Lago Chungará an important site for long-term environmental monitoring.
Long before it became a travel destination, Lago Chungará was a sacred Andean site cherished by the Aymara people. The region around the lake is dotted with archaeological remains, petroglyphs, and ancient trade routes used for thousands of years. For the indigenous communities, the volcanoes and lakes of the Altiplano represent living spirits or “apus,” guardians of the land.
The modern Aymara communities of Putre and Parinacota maintain many of these ancestral customs. Their festivals, dances, and agricultural rituals remain deeply connected to the natural cycles of the high Andes. This cultural depth enriches any visit to the Lago Chungará area, offering travelers not just natural beauty but also meaningful human stories.
Reaching Lago Chungará requires careful planning due to its high elevation and remote location, but the journey is one of the most scenic drives in Chile. Most travelers depart from Arica, the coastal city located roughly 160 km from the lake, following the Ruta 11-Ch (International Highway to Bolivia).
The road is fully paved, but due to steep inclines and fluctuating weather conditions, travelers should ensure that their vehicle is well maintained. The dramatic climb from sea level in Arica to 4,500 meters means that altitude sickness is a serious concern. It is highly recommended to spend at least one night in Putre (3,500 meters) for acclimatization before continuing to Lago Chungará.
While Lago Chungará itself is a peaceful destination, the surrounding region within Lauca National Park offers rich opportunities for exploration. From wildlife observation to trekking routes, visitors can enjoy a combination of relaxation and adventure.
Though swimming is not permitted due to environmental protections and freezing temperatures, the surrounding viewpoints offer breathtaking vistas perfect for slow, contemplative travel. Lago Chungará is not a place for adrenaline sports—it is a haven for nature lovers seeking isolation, quiet, and extraordinary landscapes.
One notable study conducted in the past decade analyzed how extreme altitude affects water oxygen levels and aquatic microorganisms. Researchers installed floating monitoring stations on Lago Chungará to measure seasonal variations. Their observations revealed that:
These findings are crucial because they help scientists understand how high-altitude ecosystems may respond to global warming. The case of Lago Chungará demonstrates that even remote, seemingly untouched environments are sensitive to subtle climatic shifts. This makes the lake a long-term reference point for Andean environmental studies.
Due to its extreme environment, the best time to visit Lago Chungará is during the dry season, from April to November. Winter months offer clear skies but colder temperatures, while summer can bring heavy rains and thunderstorms.

Visitors who follow these guidelines typically enjoy a more comfortable and rewarding experience. Local guides often remind travelers that the key to enjoying the high Andes is patience: walk slowly, hydrate frequently, and take time to appreciate the silence and vast beauty of the plateau.
There are no hotels directly on the lake’s shore due to environmental conservation policies. Most accommodations are located in Putre or Arica. Putre is the ideal base for travelers seeking shorter commuting times and a more immersive Andean atmosphere.
| Location | Type | Distance to Lago Chungará |
|---|---|---|
| Putre | Hostels, lodges, eco-lodges | ~44 km |
| Parinacota Village | Rural guesthouses | ~12 km |
| Arica | Hotels, resorts | ~160 km |
For travelers seeking cultural immersion, rural guesthouses in Parinacota offer authentic Aymara hospitality. However, amenities may be limited, so those preferring comfort and full services usually stay in Arica or Putre.
Lago Chungará stands as one of the most extraordinary places on Earth—a lake where high elevation, volcanic landscapes, ancient culture, and rare wildlife converge in breathtaking harmony. Whether you are an adventurer, a photographer, a birder, or simply a traveler seeking remote beauty, the experience of visiting Lago Chungará is unforgettable. Its calm waters, towering volcanoes, and deep cultural history create a destination unlike anywhere else in the world.
For those planning a trip to northern Chile, a journey to Lago Chungará is not merely a scenic stop—it is a profound encounter with the heart of the Andes.
