Due to the vastness of the capital, it is advisable for visitors to hire taxis whenever possible (this applies to those who are not renting their own vehicle). You can hail a taxi in the street, or you can call one to come pick you up. Taxis are generally available at the airport, hotels, and major tourist attractions.
For trips anywhere in San Juan, except to/from the SJU International Airport and the tourism piers in Old San Juan, you will pay the rate indicated on the meter. Within the “tourist zones”, taxi rates are fixed and posted. A tip of 10-15% is customary, and there is an additional charge for luggage.
Taxis are invariably lined up outside the entrance to most of the island’s hotels, but if they’re not, a staff member can almost always call one for you. If you want to arrange a taxi on your own, some reliable operators in San Juan are Metro Taxis (tel. 787/725-2870 or 725-3280), the Rochdale Cab Company (tel. 787/721-1900), and the Major Cab Company (tel. 787/723-2460 or 723-1300).
You no longer have to negotiate a fare with the driver, usually at a flat rate, for trips to far-flung destinations within Puerto Rico. There are also now established fees for taxi rides from San Juan to island destinations. Some examples, from San Juan: Fajardo, $80; Ponce, $125; and Mayagüez, $160. The complete list is available at the Puerto Rico Tourism Company website (www.gotopuertorico.com/puerto-rico-taxis.php).
