There are four international airports in the Dominican Republic. It's a big island so make sure you choose your flight correctly. We strongly recommend that you fly into is Puerto Plata (POP) as it's only 20 minutes away from Cabarete.
Avoid flying into Punta Cana at all costs unless you're going to catch a connection to Puerto Plata - driving from the East side of the island to the North Coast takes 11 hours!
You may be able to find better airfares to Santiago (1.5 hours driving distance, $60 taxi) or Santo Domingo (3.5 hours driving distance, $110 taxi).
