Swimming at Playa de Martínez is generally not recommended due to variable water quality in the Río de la Plata. The river's brownish color comes from natural sediment, but urban runoff can also affect cleanliness. Water quality reports should be checked before entering, particularly after rainfall. Most visitors use this beach for relaxation, walking, and family outings rather than swimming. The area is considered safe from a security perspective during daytime, especially on weekends when families gather. Lifeguards are not typically present, so exercise caution if you decide to wade in the water.

Playa de Martínez is enjoyable year-round, though spring (September-November) and summer (December-February) offer the warmest weather for beach activities. Weekday visits provide a quieter experience compared to weekends when local families frequent the area. Late afternoons are particularly beautiful for sunset views over the Río de la Plata. The beach remains accessible in autumn and winter for scenic walks along the San Isidro coast. Since this is a family-friendly neighborhood beach, Saturday and Sunday mornings attract more visitors, while early weekday mornings offer peaceful solitude.

Playa de Martínez is accessible via the Mitre train line from Buenos Aires Retiro station to Martínez station, taking approximately 30 minutes. From the station, walk toward the river (about 10-15 minutes). Multiple bus routes serve Martínez including lines 60 and 168. If driving, take Avenida del Libertador north; street parking is available though it can be competitive on weekends. The beach is located between Acassuso and La Lucila along the coastal promenade, making it easy to explore neighboring waterfront areas on foot or by bicycle.

Martínez is a residential suburb with various restaurants, cafés, and bakeries within walking distance from the beach, particularly along Avenida Santa Fe and surrounding streets. You'll find traditional Argentine cuisine, pizzerias, and coffee shops popular with locals. Accommodation options are limited as Martínez isn't a tourist resort area; most visitors stay in central Buenos Aires or book short-term apartment rentals. The nearby San Isidro area offers additional upscale dining options. Small vendors occasionally operate near the waterfront selling snacks and ice cream during summer months.

Playa de Martínez serves as an important coastal reference point between Acassuso and La Lucila, forming part of San Isidro's scenic riverfront. This family-oriented beach maintains a strong neighborhood character, attracting local residents rather than international tourists. Its location along the Río de la Plata's tree-lined coast provides beautiful sunset views and a peaceful escape from central Buenos Aires. Unlike commercial beach clubs, this accessible public space reflects authentic suburban life in Buenos Aires' northern zone. The beach connects to a broader coastal walkway system ideal for cycling and walking.
