The park was inaugurated as "Parque Interama" on September 21, 1982. Its sixty attractions included the Aconcagua roller coaster, the Scorpion double giant wheel, Vertigorama double roller coaster (which never opened as not all parts were delivered ), Aerogondolas (the longest Sky Ride in Latin America), the musical fountain, and a miniature railway circulating around the perimeter of the park. The observation tower reached 208 m (682 ft) upon topping out in 1981, and remained the tallest free-standing structure in Argentina until 2015.
