WD, there is no longer a Caribe Tours bus. There is a private bus that comes through Sosua about 7 am and gets to Samana about 10:15. There is no terminal, you have to wait along side the highway and flag it down. The bus is maroon in color and has a sign on the front Puerto Plata-Sosua. It is one of those Japanese type buses, but a big bus like Caribe Tours.
