5 min drive from downtown Dakar. Really easy to access. Taxi, bus, even by foot. in front of the Chiekh Anta Diop University and right next to the Terrou-Bi hotel.
Corniche ouest is a rather fun spot. Though pollution and sharks make it bad. If the swell is heavy, try to surf it, since only a few persons have, and you might be alone in the water. If the swell is small, try the suf spots of the Almadies peninsula.

The access is rather easy, though you have to walk on rocks and risk to meet urchins on your way.
