Quebrada de los Cuervos
A forested gorge carved by the río Yerbal Chico in eastern Uruguay, Quebrada de los Cuervos is a protected nature reserve offering hiking, birdwatching, and rare rocky landscapes in a country known for its flat terrain.
Quebrada de los Cuervos is a forested gorge carved by the río Yerbal Chico in Treinta y Tres Department, in eastern Uruguay. This miniature canyon — rare in a country of generally flat terrain — harbors a dense gallery forest, rocky cliffs, and remarkable biodiversity. It is one of the few places in the country where subtropical vegetation and cliff-dwelling birds coexist in an almost untouched wild setting.
Quick Facts at a Glance
- Access: managed as a nature reserve; accessible via dirt track from Route 8, approximately 25 km from the town of Treinta y Tres.
- Recommended duration: half-day (2 to 4 hours of hiking depending on the trail chosen).
- What to wear: hiking boots essential; terrain is wet and slippery after rain.
- Accessibility: not wheelchair-accessible — trails are natural and unimproved.
What You'll See
The gorge descends gradually toward the río Yerbal Chico, revealing sandstone and basalt walls covered with moss and ferns. The gallery forest forms a dense canopy above the waterway. You'll find modest waterfalls, natural pools, and, looking upward, the black vultures (Coragyps atratus) that gave the place its name — cuervos referring here to these local scavengers.
History and Context
Quebrada de los Cuervos is classified as a protected nature reserve by Uruguay's National System of Protected Areas (SNAP). Its protection aims to preserve a subtropical riparian forest ecosystem, rare at this latitude. The site sees little international tourism, which preserves its authentic wild character.
Highlights of Your Visit
The Gorge Trail
The main path follows the río Yerbal Chico at the bottom of the gorge. The rocky walls narrow in places, creating an enclosed and cool atmosphere even in summer. Passages over wet rocks require careful footing.
Birdwatching
The quebrada is a prime spot for amateur ornithologists. Beyond the vultures, you may encounter kingfishers, herons, and various forest species typical of the Uruguayan Atlantic Forest.
Pools and Waterfalls
Several small falls feed rocky pools. In the dry season, water flow decreases but rock formations remain photogenic. After rains, the spectacle is considerably more impressive.
Photography Tips
Light filtered through the canopy is most beautiful mid-morning. Waterfalls photograph well with slow shutter speeds — bring a lightweight tripod. Avoid peak sunlight: the enclosed gorge creates harsh contrasts. Vultures soar mainly late morning, when thermals form.
