Lake Titicaca, the largest lake in South America, is a high-altitude natural wonder straddling the border of Peru and Bolivia. Visits usually involve exploring the Uros Floating Islands, Taquile Island, and Isla del Sol. Accessibility can be challenging due to the altitude (over 12,500 feet), so acclimatization is essential. Both solo and guided tours are available, with guided tours offering deeper cultural insights and easier logistics. The dry season (May to September) is generally recommended for optimal weather. Costs can vary widely depending on tour type, accommodation, and transportation choices, but a multi-day trip can range from budget-friendly to moderately expensive. A typical visit lasts 2-4 days, allowing sufficient time to experience the diverse attractions. Be prepared for strong sun and bring appropriate sun protection, and consider coca tea or medications to help with altitude sickness.
