Walking can be an enjoyable way to explore San Juan, particularly in the historic Old San Juan district. This area is compact, with narrow cobblestone streets, colorful colonial architecture, and numerous attractions within close proximity. Sidewalks and pedestrian paths are generally well-maintained in this part of the city, making it accessible for walking. However, the tropical climate can be hot and humid, especially during midday, so staying hydrated and wearing comfortable clothing is essential. Outside of Old San Juan, distances between destinations may be greater, and pedestrian infrastructure can vary, which may make walking less practical in some areas.

For those interested in cycling, San Juan offers some bike-friendly infrastructure, particularly in areas like Old San Juan, where protected bike lanes are available. These lanes make it easier to navigate the historic district by bicycle. However, the city’s layout and traffic patterns may present challenges in other areas, as not all neighborhoods are equally accessible by bike. The tropical climate can also make biking less comfortable during hot or rainy periods. For those looking to explore by bike, focusing on areas with dedicated bike paths can provide a more enjoyable experience.

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.
