If you don't want to go into Marigot take the back way from OBBR past L'Oasis restaurant towards Orient. After the school take a left and that puts you on the middle road and toward Pinel Ferry road and on to Grand Case past the GC airport.

But don't go all the way to GC instead at the round about instead of right to Pinel Ferry go around and on left is Hope Estate where there is another Super U.
