Located high in the Andes Mountains, the lake sits at more than 3,800 meters above sea level and offers spectacular landscapes, traditional island communities and unique cultural experiences.

Because of its altitude, the weather around the lake can vary significantly throughout the year. Understanding the climate and seasonal patterns can help travelers choose the best time for their visit.

Most travelers explore the region through Lake Titicaca tours from Puno, which allow visitors to discover famous destinations such as the Uros Floating Islands and Taquile Island.
