Great Marsh

34 Pokémon can be caught at Great Marsh in Sinnoh — highlighted on the map below.

Serving as Sinnoh's answer to the Safari Zone, the Great Marsh occupies part of Pastoria City and shelters Pokémon found nowhere else in the region. Boggy terrain spreads throughout the area, and unlike ordinary marsh tiles, its swampy patches contain tall grass where wild Pokémon dwell.
