The park is situated on a high cliffside known as the 'barranca', providing significant elevation changes overlooking the Paraná River.
It is part of a continuous riverside corridor that links the city's urban grid to the natural waterfront.
The area is prone to fluctuations in river height, which sometimes impacts the lower-level access points during high-water seasons.
Parque San Martín is a primary urban waterfront green space located along the Paraná River in San Nicolás de los Arroyos. The park features expansive grass fields, mature trees, and direct riverbank access which serves as a central recreational hub for the city. It includes paved walking paths and specific zones for outdoor sports and family leisure activities. The terrain transitions from high-ground garden areas down to the river level. It is frequently used for local community gatherings and public events throughout the year. The park acts as a buffer between the densely built city center and the natural river ecosystem.

Bring insect repellent, as the proximity to the Paraná River often results in high mosquito activity during dusk.
Visit on a weekday to avoid peak crowds, as the park is a primary destination for local residents on weekends.
Do not attempt to swim in the Paraná River from the park banks due to unpredictable currents and muddy terrain.
Maintain noise levels during evenings; respect local 'mate' drinking culture by keeping pathways clear for pedestrians.
