Peru's lakes range from tiny pools found deep in the jungle, to great expanses of water at the base of high mountains. The largest of all is the magnificent Lake Titicaca. This big, blue, and beautiful body of water in southern Peru is one of the countries greatest natural treasures and one of the largest, deepest lakes found at altitude anywhere in the world.
Puno is the gateway to Peru's largest lake and one of the biggest high altitude lakes on Earth. Lake Titicaca straddles the Peru-Bolivia border at an incredible 12,467 feet above sea level. Surrounded by mountains, it is one of the most enchanting places in all of Peru.
Puno itself sits at an elevation of 12,556 ft and the altitude can really take some getting used to. Thankfully, there are plenty of comfortable hotels, cafes, bars, and restaurants to relax in, before taking an adventure onto the lake.
One of the joys of a trip to Puno is meeting the people who call the lake home, on various islands spread across the water. As well as day trips, you can organize a homestay with a local family.
Some people hike for enjoyment alone, while others like to walk with the goal of reaching somewhere special. In the Sacred Valley, that destination is Machu Picchu. In the Amazon, your goal is searching for critters. In Huaraz, there are lakes — astoundingly blue glacial lakes surrounded by white-capped mountains.
The most famous of the Huaraz lake treks is Laguna 69, but there are so many more options for shorter, longer, easier, and more difficult walks. Laguna Churup is a good day hike and the many azure lakes of the Santa Cruz trek can be seen over 3-4 days. The Pastoruri Glacier is another must-see; go before it starts to shrink too much!
