The beach stretches for a long distance between São Vicente and Santos, with its sandy expanse. The beach is diligently cleaned every day, and sometimes even multiple times a day, so there's no need to pay attention to those who claim it's dirty (perhaps only during busy periods or extended weekends). It's a highly enjoyable spot to spend time without having to venture outside the city, and the numerous kiosks ensure you won't go hungry.
The beach is absolutely fantastic. It can become quite busy during summer weekends but never gets overcrowded towards the south, beyond the village.
