The Red Line (literally translated as "Continent of Red Earth") is a long continent that stretches across the entire world, from North to South, along the equivalent of Earth's Prime Meridian.

The Red Line is like a group of islands connected together. The Red Line that crosses the Grand Line has its own Summer, Winter, Spring and Fall "islands".[1]

The Red Line is said to be 10,000 meters deep from ocean level to Fishman Island.[2] At the same time, it is high enough above sea level to be considered impassable, and it is indestructible,[3] meaning that it is almost impossible to pass over it or under it without using either of the entrances. Fisher Tiger, however, managed to climb up the entire Red Line with his bare hands to attack Mariejois.[4] The whole of Germa 66 was also able to climb over the Red Line, from North Blue into East Blue, using its amphibious ships.[5]

While the continent appears impossible for any boat wishing to cross between the seas or to certain sections of the Grand Line, there are certain pass points at which a ship can cross between the Blues: going up the waterways of Reverse Mountain (typically used by pirates to enter the Grand Line), gaining government permission from the holy government land of Mariejois, or submerging into an underwater passageway leading to Fishman Island, which is placed around a hole that links directly between Paradise and the New World.
