I am traveling with a group of conservation professionals to the DR in January and we will be staying at the Punta Cana Resort. We would really like to travel to Samana Bay and visit Los Haitises National Park as well as the mouth of the Yuna River. Is it possible to do this trip in a day? Is the road passible? I have heard it is in bad shape. Is there any other way to get there? What about boat or plane? Because the group will be in country for such a short amount of time, anyway to make this happen would be a really great aspect of this trip for everyone involved!!! Thanks for the feedback everyone.
