Sabaody Archipelago is an area close to the Red Line. Though it is called an archipelago, it is actually a massive mangrove forest growing out from the middle of the ocean with each tree of the forest serving as an "island" for which people live on. Since it is just a group of trees and not an island like those found in the Grand Line, it has no magnetic pull for which to affect a Log Pose.
The Sabaody Archipelago is, in actuality, a massive mangrove forest in the middle of the ocean made up of 79 separate trees known as Hustle Muscle Mangrove. The seventy nine trees are divided into several different areas, with each one dependent on the number of the area:
- 1-29: A lawless area where pirates and bounty hunters run amok
- 30-39: Sabaody Park, an amusement park with bubble-based attractions
- 40-49: A tourist area, filled with shops and souvenir stands
- 50-59: A shipping area
- 60-69: Local headquarters for the Marines
- 70-79: A hotel town
