步行是探索聖胡安的愉快方式, 特別是在歷史悠久的舊聖胡安區。這個地區地廣人知, 以鵝卵石鋪就的狹窄街道、色彩繽紛的殖民時期建築和近在咫尺的眾多旅遊景點而聞名。市區這個地區的行人路和行人路一般保養良好, 適合步行。然而, 當地氣候炎熱潮濕, 特別是在正午時分, 因此要保持身體健康, 並穿著舒適的衣物。在舊聖胡安以外, 目的地之間的距離可能較遠, 行人的基礎設施亦各有不同, 因此部分地區可能不適合步行。

對於那些對單車感興趣的人, 聖胡安提供一些適合單車行駛的基礎設施, 特別是在像舊聖胡安這樣設有受保護的單車徑的地區。這些行車線方便單車穿梭於歷史文化區。然而, 由於並非所有地區都可同樣騎乘單車到達, 並因應城市的佈局和交通模式, 對其他地區構成挑戰。氣候炎熱, 或雨季天氣炎熱, 亦可能會影響單車的舒適度。對於希望使用單車探索的乘客來說, 選擇設有專用單車徑的地區, 定能帶來更愉快的體驗。

San Juan’s public transit system includes buses and the Tren Urbano, a rapid transit system connecting parts of the metropolitan area. While these options are affordable, they may not always be the most convenient due to irregular schedules and limited coverage outside central areas. The Tren Urbano is useful for traveling between urban and suburban zones, but buses can have long wait times. San Juan’s infrastructure supports these systems primarily within the metro area, making them suitable for short distances, though longer trips or reaching less central locations may require alternative transportation.

Ferries in San Juan provide a convenient way to travel, particularly between Old San Juan and Cataño. These ferries are pedestrian-friendly and operate frequently, with crossings typically taking about 10 minutes. While they do not accommodate cars, they are a practical option for foot travelers and may allow bikes, though capacity can vary. The short travel time and ease of access make ferries a good choice for reaching nearby destinations. However, their utility depends on proximity to ferry terminals and the availability of other transportation for longer distances.
