Yasuní National Park is a remote, highly biodiverse Amazon rainforest destination in Ecuador, best accessed via flights to Coca followed by motorized canoe. Due to its challenging terrain and pristine nature, guided visits are essential and highly recommended over solo exploration, typically through multi-day eco-lodge stays or river cruises. The park is generally open year-round, though the wet season (March-August) offers higher water levels for canoe travel, while the dry season (September-February) facilitates land treks. Costs are significant, usually ranging from $800 - $2000+ per person for 3-5 day all-inclusive tours from Coca, excluding international flights. A typical visit duration of 3 to 5 days allows for a comprehensive wildlife viewing experience. Visitors should prepare for high humidity, insects, and require yellow fever vaccination and malaria prophylaxis; respecting local indigenous communities is paramount.
