From Puerto Plata to Santo Domingo

What would be the best way of travelling from Puerto Plata (La Union International) to Santo Domingo? Bus or taxi ? How much do they cost?

Thanks already for the answer !

Easy.

Normal taxi fare from Sosua to Santo Domingo airport RD$1900.00. Your best bet, if you can, is to take the bus to Santo Dimingo and then a taxi to the airport. Appox. RD$400.00 Total.

We use the bus lines fast and safe. The cost is very cheep. The ride can be cool so be prepaird for that. As for a taxi that will cost a lot. Enjoy your trip and the bus lines are on the net just can't recall the place.
Have a great trip.
