By car
It is possible but a little bit difficult to get into Senegal by car. Senegal prohibits the import of cars that are more than five years old, but if you are only staying for a short while, and agree to take your car out of the country, you should eventually be allowed through, but this cannot be guaranteed.
According to the customs of Senegel is it since 2008 again allowed to import cars also older than five years.
