Through August 9, 2026, San Nicolás de los Arroyos transforms into an interactive Ecopark with free admission. Games, fun, giant animals, and everything free await you just one hour from Buenos Aires at San Nicoland, the mega interactive park for this winter break.
Free Mega Amusement Park: Inflatables and Giant Animals
Every day through August 9, the San Nicolás Ecopark transforms into a mega amusement park for the whole family, where you can climb and jump on giant inflatables, run and scale massive structures, and enjoy the great outdoors this winter break.
Admission is free, and as if that weren’t enough, even the little ones will be able to enjoy the giant animal installations—like a jaguar—so you can explore them from top to bottom.
In fact, there are six giant, interactive animals inspired by the region’s native wildlife. Each of these giant animals is designed as an adventure park where kids can climb,slide down slides, jump, and explore secret passages.

Take the opportunity to explore San Nicolás as well, because in different parts of the city you’ll find animal sculptures that you can walk around and explore with your family.
