Turvo State Park, State park in Derrubadas, Rio Grande do Sul, Brazil

Turvo State Park covers 17,491.40 hectares in Derrubadas, northwestern Rio Grande do Sul, bounded by the Turvo and Parizinho rivers and the Uruguay River, which separates it from Argentina and Santa Catarina. It protects the state's last large area of Upper Uruguay forest, with a 20-metre canopy and emergents reaching 30 metres. The Yucumã Falls, a linear waterfall up to 20 metres high and 1,800 metres long, lies on the Argentina border.

Decree 2.312 of 11 March 1947 created the Turvo State Forest Reserve, the first conservation unit of its kind in Rio Grande do Sul, to protect untouched native forest between the mouths of the Turvo and Pari rivers. Law 2440 of 2 October 1954 turned state-owned forests over 250 hectares into state parks, making it the Turvo State Forest Park. Decree 17.432 of 11 August 1965 adjusted its limits, removing 146.1 hectares.

The falls are known in Spanish as Saltos del Moconá and have been called one of the seven wonders of Rio Grande do Sul. From 1954 visitors could reach Porto Garcia, a beach on the Uruguay River. The visitor centre holds a biodiversity exhibition and an environmental education space.

The park is accessible only on certain days with strict visitor guidelines to protect the land. Camping, fishing, and pets are not permitted, so it is best to check opening days before planning a visit.

The Yucumã Falls run lengthwise along the Uruguay River for about 1,800 metres, with drops of up to 20 metres, which is why they are called the world's longest longitudinal waterfall. On the Argentine side they are known as Saltos del Moconá. A 2015 court ruling suspended licensing of the Panambí Dam, whose reservoir would have flooded 60 hectares of the park.
