Quebrada de los Cuervos, Protected ravine in Treinta y Tres, Uruguay
Quebrada de los Cuervos is a protected ravine carved by the Yerbal Chico stream through the Sierra del Yerbal mountains, with some sections descending over 100 meters. The steep walls create a dramatic geological landscape that changes as you move deeper into the valley.
The area became Uruguay's first protected natural reserve in 1986 through a municipal decree, starting with approximately 365 hectares. This decision marked a turning point for conservation in the country and set a precedent for how natural areas could be safeguarded.
The name comes from the red-headed vultures that nest and soar above the ravine. Local residents view these birds as integral to the character of the landscape and have adapted their lives around their presence.
Access is via National Route 8 at kilometer 306, from which it is about 24 kilometers west to the protected area. Plan your visit outside the rainy season when the trails are drier and easier to navigate.
The area hosts roughly 70 percent of Uruguay's native plant species, making it a botanical treasure. This remarkable diversity often goes unnoticed by visitors, even though it makes the reserve one of the country's most valuable ecosystems.
