El Dorado is a themed park designed to raise awareness among the citizens of Rosario — especially the youngest ones — about caring for local flora and fauna. The proposal takes the dorado as its central figure, an iconic species of the littoral, known for its strength, large size, and powerful leap out of the water, and declared of national interest by Congress. This identity translates into a play installation that combines sculptural aesthetics and functionality, inviting kids to experience and understand the ecosystem through play.

The park's design represents the dorado emerging from the water. The wake is realized through interlaced light-blue pipes holding up a steel rope net that forms a large pyramid climber. The fish's body is built with a linear outline of golden pipes that create the illusion of movement, as if suspended mid-leap. Inside, the main structure incorporates climbers located in the "belly," connected to two slides symbolizing the front fins and two climbing walls representing the rear fins, expanding the possibilities for climbing, moving through, and sliding.

The area is rounded out with light-blue safety flooring simulating water, gray paths guiding circulation, and small green circles evoking water hyacinths. This combination of form, meaning, and experience turns El Dorado into an experimental playground where design inspires curiosity, movement builds knowledge, and local nature finds a new way to be explored.
