The spot lies 30 km north of Oualidia, and just before Sidi Abed, if you can't find it: ask the local people for Sidi Moussa. You have to turn left from the national road into a sandy and bushy road. Make sure you turn left before the salt fields en lakes.
If you're lucky you will also spot somes exceptional guls, ibis or even flamingos. Local kids will guard your car, for a smaal tip. It is really an excellent surf.
