Its development was preceded by the Tren de la Costa, a 16 km (9.9 mi) tourist light rail line inaugurated in 1995, and connecting Vicente López (just north of Buenos Aires) with the northern suburbs.

[3] A series of investments in the late 1990s, including the installation of two, larger rollercoasters (Boomerang and El Vigia), the addition of more live performances, and its reorganization into a theme park, as well as cost-cutting measures, reduced the unit's losses.

Debts at SCP of over US$750 million continued to jeopardize its operations, however,[1] particularly following incidents in 1999, in which two rollercoaster passengers entered into a coma, or lost their lives, allegedly due to the ride's excessive speed.

[4] A two-thirds share in the park, which netted around US$30 million in annual sales, was transferred to SCP's creditors after the company entered into an bankruptcy proceedings in 2000; a major project, the Rapidos del Delta water ride, was cancelled as a result, though other rollercoasters, built by the Dutch firm Vekoma, were opened in subsequent years.

[5] The park and Tren de la Costa (which remained in SCP ownership) helped revitalize the mainly upscale real estate market in the northern suburbs of Buenos Aires.
