The NYSC Permanent Orientation Camp in Katsina State is arranged along Mani Road. From any piece of Nigeria continue to Katsina City. From the transport stop enlist a taxi/bicycle straight to the camp. You may need to get to Kaduna or Kano in the first place, before continuing to Katsina.
Via Air: Board a plane to the Katsina Airport, from the terminal contract a taxicab to the NYSC Camp. The Kano Airport is another choice.
