By Bus — The Metropolitan Bus Authority (tel. 787/767-7979 for route information) operates buses in the greater San Juan area. Bus stops are marked by upright metal signs or yellow posts that say PARADA. The bus terminal is the dock area in the same building as the Covadanga parking lot next to the Treasury Department. Fares are 75¢. Three routes are particularly useful for tourists, those that carry San Juan passengers from Old San Juan to other San Juan tourism districts: The A5 goes to downtown Santurce, Ocean Park and Isla Verde; the B21 down Condado’s Ashford Avenue and then on to downtown San Juan, the city’s financial district Hato Rey and the Plaza Las Americas mall; and the C53, which heads to the Convention Center District, then down Condado’s oceanfront drive and on into Isla Verde. Call for more information about routes and schedules. The private MetroBus operates a few key express routes from Old San Juan to Río Piedras for 50¢.
One useful route is the A5, which hits downtown Santurce, Avenida de Diego near Condado, then goes along Loíza Street and down Isla Verde’s oceanfront drive where all the hotels are located. You can switch to the B21 at De Diego Street, if you want to go down Condado’s main drive, Avenida Ashford.
The B21 runs from Old San Juan to Condado, while also servicing Plaza Las Americas. The privately run MetroBus runs express buses between Old San Juan and Río Piedras, with stops in Hato Rey and Santurce.
Any bus marked ATI hooks up with the Tren Urbano, probably at its Sagrado Corazón Station, which is its last stop into the city. The ticket has been slashed in half to 75¢ to encourage ridership and put it on par with bus rates.
