Parque provincial Aconquija, Provincial park in Yerba Buena Department, Argentina.

Parque Provincial Aconquija is a protected mountain forest covering hundreds of hectares with dense vegetation and diverse tree species including laurels and horco molle. The park features multiple trails for walking and cycling that wind through the forest, allowing visitors to explore the local plant and animal life.

The area became a protected reserve in 1936, marking an important early step in environmental conservation for the Tucumán region. This designation showed that local authorities recognized the need to safeguard the mountain forests from development.

The park's name comes from the Aconquija range, and its 1936 creation under provincial law 1672 made Tucumán a pioneer in Argentine heritage protection. The original law set aside at least 500 of some 2000 hectares as a forest reserve; later cadastral surveys fixed the protected area at 226 hectares. Nearby Parque Sierra San Javier and Reserva Horco Molle complement it.

Wear sturdy footwear since the trails traverse mountain forest terrain with varying levels of difficulty. It helps to visit in the morning hours when lighting is best for walking and wildlife observation is most productive.

The source lists the Tucuman Amazon, Great Dusky Swift, Grey Elaenia and Yellow-striped Brushfinch as endemic, but this is a claim about the region rather than the park alone. Around 200 bird species have been recorded in and around the park, alongside cats such as the puma, jaguarundi and ocelot.
