Panama is located on the Isthmus of Panama, the narrow bridge of land that connects North and South America. It is bordered by Costa Rica to the west and Colombia to the southeast. Its capital, Panama City, is a modern metropolis known for its skyline and proximity to the rainforest. The country's most significant geographical and economic feature is the Panama Canal, which allows ships to pass between the Atlantic and Pacific Oceans without sailing around the southern tip of South America. Interestingly, because of the S-shape of the isthmus, the sun rises over the Pacific and sets over the Atlantic in certain parts of the country. Panama's terrain is mostly steep, rugged mountains and upland plains, with coastal lowlands. It possesses a tropical climate and is home to a vast array of biodiversity, particularly birds and trees. It is the only place in the world where you can see the sun rise on the Pacific and set on the Atlantic from the same spot.
