Does anybody know what direction to walk to the hole at the end of the Trou de David Road road?

Hope the screen capture below helps.

Yes the drawing helps very much thank you.
It's called a tourist attraction in the publications but we went there and it looks like you have to either be in a boat or climb the cliff to see the attraction. It's very close to the ruins of La Belle Creole. You turn left going towards Marigot immediately after the entrance to a Bay Rouge.
