The Puerto Rico Tourism Company has instituted a well-organized taxi program. Taxis painted white and displaying the taxi turistico logo charge set rates depending on the destination; they run from the airport or the cruise-ship piers to Isla Verde, Condado/Ocean Park, and Old San Juan, with fixed "zone" rates ranging from $10 to $19. If you take a cab going somewhere outside the fixed zones, insist on setting the meter. City tours start at $30 per hour. Metered cabs authorized by the Public Service Commission start at $1 and charge 10¢ for every additional 1/3 mi. In other Puerto Rican towns, you can flag down cabs on the street, but it's easier to have your hotel call one for you. Either way, make sure the driver is clear on whether he or she will charge a flat rate or use a meter to determine the fare. In most places, the cabs are metered.
