I posted about it on another link SXM WITH 12 yr old. If you search

I wrote directions from Philipsburg

Go to end of Front Street turn left (right goes to cruise ship dock). Follow signs Captain Oliver's and Oyster Pond. At Oyster Pond (marina at right, Pizza place on left) go down hill bear right. at this turn in road is L'Oasis restaurant (formally Le Frigaate). Follow road BZH crepeire on left (great food) A little further about 2 miles is an area overlooking shales, Le Galion beach, St Barts, parasailers. Pull anywhere off road. Can wade out in shallow water to little sand bars.

There used to be a platform to climb up for better view but I'm not sure it survived hurricane. Bring a camera!
