Getting to Senegal

Freighters World Cruises

If your in the United States you must fly or take a boat. From Europe it is possible to drive down, but not recommended. Well as for a boat there is no scheduled service. You can try what my father did years 
ago.. he took a freighter for the New York to  Nigeria.  The problem is  that the ship probably will make many stops along the way. It can take weeks and since its not a recreational cruise line you better pack a lot of books to read. The crew is not there to entertain you. If you insist click this link for Freighters World Cruises Inc. There are people who have the time and insist this the only way to travel.

South African Airways

So... from the United States that leaves flying.  You can fly via  Europe or Morocco and connect to Dakar. This  will make for a long trip anywhere from 16 to 25 hours with the layover.  45 flights per week fly out of New York, NY connecting to Dakar,. In a hurry then get a direct  flight on Delta Airlines out of JFK or on South African Airlways, from Washington, DC it is a non stop flight. Travel time is 7  1/2 hours outbound and 9 1/2 return. Not sure why the return takes and addition 2 hours. Maybe some pilot will let me know :-)
