Praia de Itaipuaçu is a long, sandy beach stretching approximately 15 kilometers along the coast of Maricá within the Rio de Janeiro metropolitan area. The beach is public, with a sandy shoreline and parking available. The sheer length of the beach suggests multiple potential launch sites, but paddlers should be prepared for a carry across the sand to reach the water. The coastline is exposed to the open Atlantic Ocean, making it susceptible to wind, waves, and ocean swells. The character of the surf and shore-break can vary significantly along such an extensive shoreline, requiring careful assessment of conditions at the chosen launch point. The beach is noted for having a long, open orla, or waterfront, lined with various quiosques and restaurants, providing amenities for food and drink. The overall vibe is that of a spacious, natural beachfront with infrastructure for visitors.

For paddlers, the primary destinations reachable from this beach are other nearby coastal features. The beach's western end is a location for motorized hang gliding tours, indicating a potential point of interest. Other notable beaches and lagoons in the region, such as Itacoatiara, Itaipu, Barra de Maricá, and Ponta Negra, as well as the lagoas of São José de Imbassaí, Guarapina, and Maricá, are places adventurers can explore, suggesting they are within paddling distance or represent logical destinations for a longer coastal journey. Seasonal climate data indicates the warmest and driest months, with lower rainfall, are from May through August, which could present more favorable paddling conditions. Water temperatures likely follow the regional pattern, being warmest during the Southern Hemisphere summer months from December to March.
