Transportation
Although most beaches and the centre of Sosua are within walking distance, you can make use of several transport possibilities.
A ride on a "motoconcho" is really exciting. For just 10 pesos they bring you around Sosua at the back of a minimotor.
Ofcourse you can also take a taxi. Make an agreement for the price before you get in the car.
If you like the real adventure you can take the "carro publico" or the "guagua" (bus). This bus is never full, they can always take more and more passengers.
In Sosua there are several rent-a-car companies. Rent your car at a well-known company and read the (insurance)conditions very carefully.
