The Great Marsh (Japanese: だいしつげん Great Marsh) is an area located in Pastoria City. It is Sinnoh's Safari Zone and contains some Pokémon that cannot be found anywhere else in Sinnoh. It is filled with marshy areas, which, unlike normal marsh tiles, have tall grass which are inhabited by wild Pokémon.
Much like other Pokémon preserves in Kanto and Hoenn, the Great Marsh features a Safari Game in which Trainers pay 500 for 30 Safari Balls and a limited number of steps (500) to catch all the Pokémon they can. With a large area to cover, Trainers must plan out their destination so as to arrive in time to capture all the Pokémon they want. The mechanics are not too different from other Safari Zones.
The most important of their specific mechanics, however, is that trainers do not initiate Pokémon battles with the wild Pokémon, but instead must catch them without harming them. The wild Pokémon within Safari Zones are capable of fleeing at any given time, which can cause certain levels of frustration among players who encounter particularly rare species, or even shiny Pokémon. When a wild Pokémon appears, no Pokémon may be sent out to battle it: catching Pokémon here, as in all Safari Zones, requires sheer luck. There are four options in the battle screen:
- Throw a Safari Ball - Throws a Safari Ball in possibility of capture. It is much the same as throwing a Poké Ball in an average Pokémon battle.
- Throw mud - Throwing mud makes a Pokémon easier to catch, but makes it more likely to flee from battle
- Throw bait - Throwing bait does the reverse of throwing mud, making a Pokémon less likely to run but harder to catch.
- Run from battle - Like in an average Pokémon battle, running away from a Pokémon will cause the battle to end.
Similar to the issue in the Pal Park, if the player has an Arceus in the front of their party, holding a plate, and intiates a battle, the game will freeze.
The area was redesigned in Pokémon Platinum to feature slightly upgraded graphics that allow the player to distinguish between deep and shallow mud. The park is still divided into six areas, but the individual areas have slightly different layouts.
Some Pokémon will not always appear in the Marsh. Each day, the Pokémon will change, therefore, to get a new set, players must wait a day. These Pokémon will appear randomly in one of the six areas, some may not appear for a while, while others appear several days in a row or in multiple areas on the same day. Some may not appear until after getting the National Pokédex. The only way to tell which changing Pokémon is available in the areas for the day is to use the lookout upstairs from the entrance. Mixing records also changes the changing Pokémon of the day in the Great Marsh so all players mixing records have the same Pokémon on the same day.
In order to find out what Pokémon are going to be in each area daily, the player is able to walk up to the second floor in the lobby, and use the binoculars and look out onto the marsh. For 100 players can get a brief glimpse of the Great Marsh showing certain Pokémon in certain areas of the marsh. In each slide, a part of the park will appear with a Pokémon in the center of the slide that can be found in that area.
In all six areas, the Pokémon able to be caught are exactly the same.
In Platinum, more Pokémon are available before the National Pokédex. The new additions are:
| A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
In the anime
As a boy, James was exploring the Great Marsh, and found a Carnivine stuck in the mud, struggling to get free. James pulled it out, and they became friends. Carnivine has been James's friend ever since, and since he most recently arrived in Sinnoh, has been traveling with James.
In Cream of the Croagunk Crop!, Brock and his Croagunk participate in a Croagunk festival held in the Great Marsh.
