You have several options. Rental car, chartered flight, taxi or bus. Depends on your financial resources, among other things.
The cheapest way to get there in comfort is to take the Caribe Tour bus from Puerto Plata or Sosua. It leaves Caribe Tours' Puerto Plata terminal at 7am, leaves Sosua at 7:30 am, and arrives in Samana about 11:45 am.
In Samana, you can take public transportation to get to Las Galeras, the beautiful beach area at east end of Samana Peninsula. You should also visit Las Terrenas on the Atlantic side of the peninsula. I believe you can now get there from Samana by public transportation, also.
Muchos Gracias, for your help!!! I look forward to visiting Samana I hear it is beautiful!
Do you know what a cab ride would cost? curious?
I am on a budget the Caribe tour bus would probably be a good idea for me.
Music, I don't know what taxi is from Puerto Plata to Samana, but I would estimate about RD$1,500. Caribe Tour will be around RD$100. I say "arround" because there have been fare hikes recently and I haven't bought a ticket since then.
