One natural wonder that locals are truly proud of, Mount Mayon sits in the Filipino province of Albay. Mayon is an active volcano (the most active in the country) that is famous for its seemingly perfect symmetry. Standing at nearly 2,500m (8,200ft), its flawless conical shape captivates anyone who sets eyes on it. And while viewing it from afar is a sensational sight, it is best experienced up close through a multi-day hike.
