Noir Forest (Japanese: サマヨイのもり Samayoi Forest) is a location in Pokémon Ranger: Guardian Signs.
It is located south of the Old Mansion and northeast of Mitonga Road on Mitonga Island. Players must avoid the light released by the Dusclops because having the light shined on the player will return them back to the entrance. The Dusclops act as bodyguards. They can be captured by running into them from behind. There are many Fallen Logs in Noir Forest. Once all Dusclops are captured, Dusknoir will appear.
