There should be no major changes with the road to El Rincon as this area was not significantly affected by Hurricane Georges. It is possible that the ferry connecting Sabana de la Mar with Samana will be operating, permitting the transport of vehicles. I would be wary of driving in the area of Los Haitises, even with a 4 wheel drive as these roads have never been good, with or without hurricane. I think you will get to see much more if you take an organized excursion to the Haitises area.
