The Great Marsh is the safari zone of Pokémon Brilliant Diamond & Shining Pearl, and it is filled with rare Pokémon to catch and items to find. Safari zones in every Pokémon game are essentially mini-games in which players are presented with a limited number of Safari Balls to catch as many Pokémon as possible. Additionally, players are also presented with the challenge of being able to only walk a certain number of steps.

One of the defining features of the Great Marsh in Pokémon Brilliant Diamond and Shining Pearl is the trolley system. The trolley system is a free means of transportation that takes players to various areas of the Great Marsh without costing them any of their limited 500 steps. It's also the easiest way to access Pokémon in certain areas. Once the National Dex is unlocked in Pokémon BDSP, trainers will want to make sure they take full advantage of the trolley system to access more rare Pokémon.

The Great Marsh is located in Pastoria City in Pokémon Brilliant Diamond and Shining Pearl, and it's available at any time. To explore the Great Marsh, players will have to pay 500 Poké Dollars at the entrance counter. Additionally, players can pay another 100 Poké Dollars at the binoculars on the second floor of the same building to see which Pokémon are available in which area. New Pokémon are in the Great Marsh every day, and knowing which ones are located in which area is imperative to catch them all. The Defog HM in Pokémon BDSP is also located in the Great Marsh and is given out by an NPC with green hair to the right of the entrance.

Although the majority of encounters in the Great Marsh in Pokémon Brilliant Diamond and Shining Pearl are for common Pokémon like Starly, Bibarel, and Wooper, players can find the rarer encounters rotating daily. Additionally, having fishing rods grants more access to purely aqua-based Pokémon like Magikarp and Barboach. The better the fishing rod players bring with them and use, the better the Pokémon they can catch. With a Super Rod, players can even catch Whiscash, Carvanha, and Gyarados in the Great Marsh. The Super Rod in Pokémon BDSP can be found by speaking with an NPC fisherman on Route 225.
