San Juan on a budget

Best free attractions

San Juan's best free hours are spent outside, and the city knows it. The old walled quarter is stitched together by plazas, each with its own temperament and its own hour when it comes alive; the modern city answers with parks that stretch from the shoreline out into Bayamón and the botanical acreage on the edge of Río Piedras. This list covers seven such addresses: four historic squares in Old San Juan, two municipal parks, and a working botanical garden, none of them charging you a peso to walk in. They are for the traveller who has budgeted for the forts and the ferries and would rather spend an unhurried afternoon reading the city the way locals do: on a bench under a laurel, with a paper cone of shaved ice, watching the light shift on the paving stones. Coordinates and Wikidata identifiers ground every entry so you can plot a walking morning through the old town or a longer bus ride south to the greener acreage; the editorial pass is a local's read of which square rewards which hour, and which park is worth the cab.
