The park hosts a rich diversity of wildlife, particularly birds, with over 200 species recorded. Notable avian species include the rufescent tiger-heron, black-crowned night-heron, and various types of ducks and kingfishers. Mammals found in the park include capybaras (the world's largest rodent), river otters, and marsh deer. The waters support numerous fish species, including sábalo, dorado, and surubí. Reptiles such as the yellow anaconda and various species of turtles are also present in the park's aquatic environments.
The vegetation in Predelta National Park is typical of subtropical riverside forests and wetlands. The park features several distinct plant communities, including gallery forests dominated by ceibo trees (Erythrina crista-galli), willow forests (Salix humboldtiana), and extensive reed beds (Scirpus giganteus). Aquatic plants such as water hyacinth (Eichhornia crassipes) and water lilies are abundant in the wetland areas. The park also contains significant stands of native grasses and sedges that are adapted to periodic flooding.
The park is situated within the Paraná Delta system, characterized by alluvial islands and wetlands formed by sediment deposits from the Paraná River. The landscape consists of low-lying islands, marshes, and channels created through continuous fluvial processes. The soil is primarily composed of fine sediments carried downstream by the river, creating a dynamic environment that constantly evolves through natural erosion and deposition cycles. The elevation rarely exceeds 5 meters above sea level, and the terrain is characterized by its flat, wetland topography.
Established in 1992, Predelta National Park was created to protect a representative sample of the Paraná Delta ecosystem and its islands. The area has historically been used by local communities for fishing and small-scale agriculture. Before becoming a national park, the region served as an important navigation route during colonial times, connecting the interior provinces with Buenos Aires. The park's establishment marked a significant step in preserving one of Argentina's unique river delta ecosystems, which had faced increasing pressure from development and agricultural expansion.
Key attractions include the network of waterways perfect for kayaking and boat tours, observation towers providing panoramic views of the delta landscape, and interpretive trails through the gallery forests. The park's location near the city of Diamante makes it easily accessible for visitors. The constant interaction between land and water creates a unique ecosystem that changes dramatically with water levels, offering visitors different experiences throughout the year. The park is also an important site for bird watching, scientific research, and environmental education programs.
Predelta National Park experiences a humid subtropical climate typical of the Entre Ríos region. Summers (December to February) are hot and humid with temperatures reaching 30-35°C (86-95°F), while winters (June to August) are mild with temperatures ranging from 10-20°C (50-68°F). The park receives significant rainfall throughout the year, with an annual average of 1,000mm, though spring and autumn tend to be the wettest seasons. Flooding is common during heavy rain periods, particularly when the Paraná River levels rise.
