Lake Pehoé, located in Torres del Paine National Park, is a stunning glacial lake renowned for its vibrant turquoise waters and breathtaking views of the Paine Massif and surrounding mountains. Access to the lake is generally good via park transportation or private vehicles, though some viewpoints may involve short hikes. While solo exploration is possible for experienced hikers and trekkers, guided tours are highly recommended for navigating the park's trails and understanding the local flora and fauna. The peak season is during the austral summer (November to March) when the weather is more favorable, but this is also when the park is most crowded and expensive. The shoulder seasons (October and April) offer a balance of good weather and fewer crowds. Expect to spend at least a full day, or ideally several days, exploring the lake and its surrounding trails. The cost can vary greatly depending on accommodation choices, transportation, and tour options, but budget accordingly for park entrance fees, transportation within the park, and potentially expensive lodging.
