Marshes (湿地, Shitchi?), also called Swamp, are a recurring type of terrain of the world map in the Final Fantasy series. Their location varies, but they are often inhabited by the Undead. They can always be traveled on foot.
There is one area of marshlands in the game, located in the Grasslands Area, by the Chocobo Farm. It is home to the Midgar Zolom, a species of gigantic snakes. A chocobo can be used to cross the marshes faster than the area's endemic snakes. The player does not engage in Random encounters in this area.
The player can enter a one-time field location after crossing the marsh where a Midgar Zolom slain by Sephiroth is seen.
Qu's Marshes are found throughout the world, there are four such marshes; one on the Mist Continent, one on the Outer Continent and two on the Forgotten Continent. They are home to the Qu species and are filled with frogs, a Qu delicacy.

Clearwater Marsh is an area in the western Archylte Steppe. To get there, the player will need to use a cactuar waystone that is found in a tornado during the windy weather. There is another cactuar waystone in Clearwater Marshes (northeast) behind a rock. It needs to be uncovered with Moogle Hunt in sunny weather. A third statue is found in Clearwater Marshes (Central) that needs to be uncovered with Moogle Hunt in rainy weather.
This area can be used for farming components.
In Clearwater Marsh (Sunny), the Microchu spawns in mass numbers, allowing the player to collect many Potent Crystals, as well as the rare item component Sunpetal, making this the best location for farming Grade 5 biological monster components. It is also reasonably frequent during the rainy season, allowing the player to collect a number of Potent Crystals at the same time as collecting Potent Essences.
