The Madre River estuary acts as a natural nursery for various local fish species.
The village was originally a small fishing community before gaining international attention as a surfing destination in the 1970s.
The sand dunes at the southern end are part of a protected ecosystem that limits pedestrian access to preserve vegetation.
The river crossing depth varies significantly depending on the tide and recent rainfall levels.
It is classified as one of the few places in Brazil where river and sea converge in a direct, swimmable sandbar formation.
The local municipality enforces strict height limitations on buildings to maintain the visual landscape.
Guarda do Embaú is defined by the intersection of the Madre River and the Atlantic Ocean, creating a narrow sandbar that separates the river water from the sea. Visitors must cross the shallow river mouth, typically by wading or paying for a small local boat transport, to access the main beach stretch known as Praia da Guarda. The beach is situated within the Serra do Tabuleiro State Park, a protected environmental area. The unique geography creates a calm, freshwater lagoon environment alongside powerful Atlantic surf breaks. The village maintains a bohemian atmosphere with unpaved streets and restrictive development codes. The area is globally recognized for consistent surf conditions, frequently hosting professional surfing championships. The main beach is backed by rocky cliffs and dunes, providing a natural barrier against large-scale urbanization. Coastal currents in the river mouth can be strong, necessitating caution for swimmers.

Bring a waterproof bag for your electronics if you plan to wade across the river mouth.
Check the tide charts before visiting, as high tide can make the river crossing significantly deeper.
Bring your own shade equipment, as there is no natural shade directly on the sandbar.
Do not attempt to swim across the river mouth during heavy rain or strong tidal currents as the pull toward the ocean is dangerous.
Casual beachwear is standard; however, remain mindful of quiet zones in the residential village areas.
