Finding a taxi in Puerto Rico is usually no trouble. Cabs and shuttles are often located outside the main exits of tourist attractions or hotels' front doors.
Taxis can be hailed around town on the street, or you can call one to come to pick you up. Trips around San Juan are metered fares. Within areas designated as “tourist zones,” the rates are fixed and posted. The fares are paid — cash only — to the drivers. Tolls and tips are not included. An additional fee for luggage, late-night, and airport drop-offs may be charged.
Upon arriving at the airport, taxis are waiting outside Terminal B and C exits or Terminal A on the Arrivals Level. The airport has taxi dispatchers that advise passengers about the costs of their trips before they get into a cab.
There are other fixed rates for travel between towns and points of interest outside the San Juan District if you want to take a day trip but would prefer not to rent a car of your own.
