Situated at an altitude of 3,860 m, Puno is a town of 145,000 inhabitants at the western end of the renowned body of water.

This high-altitude body of water, straddling the border between two South American nations, is the largest freshwater lake in the continent. Known for its deep azure waters and the snow-capped Andean peaks that surround it, it is a sight to behold. The lake's surface area spans over 8,300 square kilometers, making it an impressive spectacle of nature's grandeur.

The lake is not just a natural wonder, but also a cradle of ancient civilizations. It was once the center of the Tiwanaku empire, a pre-Incan civilization that thrived around 500 to 1000 AD. The remnants of this civilization can still be seen today in the form of submerged archaeological sites and ancient ruins on the lake's islands.

One of the lake's most unique features is its floating islands, made entirely of totora reeds. These islands are home to the Uros people, who have lived on and around the lake for centuries. The Uros people's way of life is deeply intertwined with the lake; they use the totora reeds not just to build their islands, but also their homes, boats, and crafts.

The lake is also a haven for wildlife. It is home to several species of fish and birds, some of which are endemic to the area. The lake's biodiversity makes it a popular spot for birdwatching and fishing.

The lake's beauty and cultural significance have made it a popular tourist destination. Visitors can explore the lake by boat, visit the Uros people's floating islands, or hike in the surrounding Andean peaks. The lake's islands also offer unique accommodation options, allowing visitors to immerse themselves in the local culture.

Despite its popularity, the lake faces several environmental challenges. Pollution and overfishing threaten its biodiversity, while climate change threatens its very existence. Efforts are being made to protect and preserve this unique ecosystem for future generations.
