Laguna Grande in Argentina is referenced in two distinct geographical contexts, both offering paddling opportunities. In the province of Entre Ríos, it forms part of the Paraná - Victoria vía Paraná River and Laguna Grande Paddling Route. This route is designated for paddle sports, including canoeing, kayaking, and stand-up paddleboarding. The water body is connected to the Paraná River system, suggesting a riverine or wetland character.

A separate Laguna Grande is located in the high-altitude region of northern Argentina, within the Antofagasta de la Sierra department of Catamarca province. This site is described as an important wetland. The primary paddling season here is understood to be between October and March. The area is part of a high-altitude route that includes Laguna Diamante, starting from a village at approximately 3,400 meters (11,155 feet) and reaching Laguna Diamante at around 4,200 meters (13,780 feet). The extreme elevation defines the experience, presenting significant physiological considerations for paddlers. The aesthetic is one of a stark, high-altitude landscape.
