The narrowest point of the Strait of Gibraltar is known as the Pillars of Hercules, which are the rock formations located at either end of the strait: the Rock of Gibraltar on the European side and Monte Hacho on the African side. This narrow point measures approximately 13 kilometers (about 8 miles) across. The strait serves as a vital waterway connecting the Atlantic Ocean to the Mediterranean Sea.

The Panama Canal cuts across the isthmus in Central America, providing a shortcut for ships traveling between the Atlantic and Pacific Oceans.
The Northwest Passage is the name that European explorers gave to a theoretical waterway that would pass through the Americas and connect the Atlantic to the Pacific Oceans. However, there is no "Northwest Passage." However, the Pacific is directly connected to the Atlantic between South America and Antarctica, as well as through the Strait of Magellan. Today, however, ships often travel between the Atlantic and Pacific Oceans via the Panama Canal, a man-made waterway across the nation of Panama in Central America.
