Formosa

Capital of Argentina's Formosa province, this riverside city sits on the right bank of the Paraguay River, facing the Paraguayan town of Alberdi, with a walkable centre offering cafés, restaurants, and a Central Square named after José de San Martín. Notable sights include the Nuestra Señora del Carmen Cathedral, the Torelli Botanic Forest Garden, the Provincial History Museum, and the Guaicole fauna reserve. Nearby, Laguna Oca — a former channel of the Paraguay River declared a biosphere reserve in 2001 — adds a natural draw to the surrounds.
