Sangay National Park, a UNESCO World Heritage Site in Ecuador, is renowned for its diverse ecosystems, ranging from tropical rainforests to glaciers, and its active volcanoes. Accessibility is challenging due to the park's remote location and rugged terrain, making guided tours almost essential and independent exploration difficult. The park is best visited during the drier months (June to September) to avoid heavy rains and landslides. Costs can vary significantly depending on the tour operator and duration, but expect to pay a substantial amount for transportation, permits, and guides. A typical visit can range from a few days to a week or more, depending on the areas explored. Be prepared for altitude sickness and varying weather conditions.
