45 kilometres (28 miles) away from Colón by national route 14, it is one of the latest national parks in Argentina since it was created by law on January 28, 1966. From its front access a main way crosses the entire park in direction to the River Uruguay. This route has deflections leading to lovely viewpoints.

Near the river bank there is a Visitors Centre, the Intendancy and a small museum with pictures and other elements of the park’s flora and fauna. The land is smoothly waved, furrowed by streams and populated by Yatay Palm. This palm grows only in a few places in Brazil, Uruguay and Paraguay, but in no one does it proliferate as much as in this national park. Many of them are up to 800 years old and 25 to 30 metres (82 to 98 feet) high.

Not only there is a palm forest into the park, but also a forest gallery that reaches the Uruguay banks, and the low lands with aquatic vegetation.

Among the fauna of the park, birds such as the hooded siskins, vermilion flycatchers, common potoos, cardinals, chalk-browed mockingbird, hummingbirds, ducks, storks and several types of eagles stand out. It is possible to see as well some running rheas, species extinguished elsewhere.

Within the park a pedestrian path is to be visited, el Mollar, which ends up in La Glorieta square, a viewpoint on a 50 metre (164 foot) ravine.
