The protected area is home to a rich variety of wildlife, including over 130 bird species, making it a premier birdwatching destination. Notable species include the black-and-white hawk-eagle, the buff-fronted owl, and various hummingbirds. Mammals found in the area include capybaras, margays, and several bat species. The ravine also harbors numerous reptile species, including the rare Darwin's snake, and various amphibians adapted to the unique microclimate.
The area hosts a remarkable diversity of plant life, with over 400 documented species. The vegetation varies from native forest in the ravine bottom to grasslands on the upper plains. Notable species include the rare Butia palm, numerous ferns, and endemic orchids. The canyon's sheltered environment creates perfect conditions for several species of moss and lichens. The native forest includes prominent species such as the Coronilla, Guayabo, and Arrayán trees.
The canyon was formed over millions of years through erosion by the Yerbal Chico stream cutting through ancient crystalline basement rocks dating back to the Precambrian period. The ravine reaches depths of up to 100 meters and extends for several kilometers, featuring dramatic vertical walls and exposed rock formations. The geological composition includes metamorphic rocks, primarily gneisses and granites, which create the distinctive reddish-brown coloring of the cliff faces.
This dramatic landscape has been a significant site since pre-Columbian times, when indigenous peoples used the area for hunting and gathering. The ravine got its name ('Ravine of the Ravens') from the black vultures that historically nested in its cliffs. In 2008, it became Uruguay's first officially protected area under the National Protected Areas System, marking a milestone in the country's conservation efforts. The area has traditionally been used for cattle ranching, which continues in designated zones today.
The main attraction is the dramatic canyon itself, with its impressive viewpoints offering panoramic vistas of the landscape. The Yerbal Chico stream creates several small waterfalls and natural pools perfect for swimming during summer months. The area features well-marked hiking trails of varying difficulty, including the popular 'Sendero de la Cascada' leading to a scenic waterfall. The visitor center provides educational exhibits about the area's ecology and offers guided tours. The site also includes designated camping areas and picnic facilities for day visitors.
Quebrada de los Cuervos experiences a temperate climate with four distinct seasons. Summers (December-February) are warm with average temperatures around 25°C (77°F), while winters (June-August) are mild with temperatures ranging from 5-15°C (41-59°F). Rainfall occurs year-round but is slightly higher in spring and autumn. The deep canyon creates unique microclimates that can differ significantly from surrounding areas, with higher humidity levels and more moderate temperatures within the ravine itself.
