Hi - The best thing to do is depending on how many people will be travelling, to charter a plane. If you have more then 4 - it makes sense. You can PM me with details and I will get a rate for you for a charter flight from Punta Cana to Puerta Plata Airport. If that is the route you want to go - there are other ways, via ground transport thru Santo Domingo -but basically its a day trip however you look at it from one side to the North Coast via ground.
