The Rio da Barra in Bahia, Brazil is a coastal river that flows into the Atlantic Ocean, creating a beach of the same name near Trancoso and Arraial d'Ajuda. The river meets the sea at a wide, sandy beach characterized by very clean sand and water. The overall character is one of natural beauty with fewer people compared to other local beaches. For paddlers, the river's mouth and the adjacent mangrove areas are the primary features of interest. The area is noted for ecological tourism, with opportunities for boat tours through the mangroves, which are ideal for bird watching and observing the local ecosystem. The river current itself is noted as a beautiful feature where it flows from the mangroves onto the beach. A significant safety consideration is the tide. At low tide, it is possible to cross the river mouth on foot, but at high tide, the crossing becomes difficult or impossible, which is a critical factor for planning access or a return trip. The waves on the beach are reported to be strong. The beach is accessible via a scenic 40-minute walk from Trancoso or by a 9km drive along the Old Trancoso's Road. Commercial boat tours in the mangroves suggest that paddling, such as kayaking, is a viable activity in the calmer river and estuary sections, away from the strong ocean surf. Wildlife sightings can include whales offshore from the beach.
