If u have never been to imbert, u might consider driving to POP. Its not the campo but not far off if u see what I mean.
I would NOT consider the cabana on ure left when u drive towards POP
I don't think there is one. Some friends of mine tried to stay there last year (after cycling back from Cap Haitienne) and failed. They wouldn't even let them take a room for a night in the cabana…only 'por un rato'
