Public transportation is available throughout the San Juan metro area. The Department of Transportation and Public Works (DTOP) has designed a network of 30 bus routes throughout the whole metro area, including Toa Baja, Cataño, Bayamón, Guaynabo, San Juan, and Carolina. A light rail line (Tren Urbano) connects three municipalities (San Juan, Guaynabo, and Bayamón).
The two Routes servicing the Isla Verde area are Route 5 (Iturregi) and Route 53 (Airport).
Bus fare is 75¢, while one Tren Urbano trip costs $1.50. In order to use either buses or the train, passengers need to purchase a transit pass at any Tren Urbano station. Exact fare, day-, weekly-, and monthly-unlimited passes are available. Transfers from train to bus and vice versa within two hours are free.
Regular buses operate from 5 a.m. to 9 p.m. on weekdays, and from 6 a.m. to 8 p.m. on Saturdays and holidays. Metrobus buses (routes I and II, and Express) operate daily from 4:30 a.m. to 10 p.m.
