The Cebollatí River is one of the longest rivers in Uruguay, with a length of approximately 235 kilometers. It originates in the Cuchilla Grande in the Lavalleja Department and flows northeast, forming the border between the departments of Rocha and Treinta y Tres, before emptying into the Laguna Merín. Its basin of 14,085 square kilometers is one of the largest in the country and is critically important for rice cultivation, a mainstay of the regional economy. The river is navigable by small boats and plays a significant role in irrigation. The river's ecosystem is part of the larger Bañados del Este wetland system, which has been designated as a Wetland of International Importance by the Ramsar Convention. This region is a paradise for birdwatchers, hosting hundreds of avian species. The name 'Cebollatí' is derived from the Guaraní word 'cebolla-tí', meaning 'field of onions', referring to the wild onion plants that were once abundant in the area.

📋 Practical info
Getting there
The Cebollatí River is usually accessed via regional roads connecting to the closest towns, where local transport or unpaved trails guide visitors to the banks. The final approach often involves navigating uneven natural terrain.
Best season
The dry season is typically the best time to visit, providing calmer waters and safer conditions for exploring the surrounding natural areas. During the wet season, heavy rainfall can cause water levels to rise rapidly.
Terrain & paths
The surrounding landscape typically features dense vegetation, rocky embankments, and muddy trails that can become quite slippery. Navigating the riverside requires careful footing due to frequent natural obstacles and uneven ground.
What to bring
Visitors should bring sturdy waterproof footwear with solid traction, reliable insect repellent, and adequate sun protection. A dry bag is highly recommended to ensure essential electronics and spare clothing remain protected from moisture.
Parking
Parking is generally available in designated spots within nearby towns or at informal clearings near the main access paths. It is strongly advised not to leave valuables inside unattended vehicles when parking in remote natural locations.
Safety
Always remain alert to sudden changes in river currents, which can be unexpectedly powerful even in seemingly calm stretches. Avoid swimming in unfamiliar or fast-flowing areas, and be cautious of slippery rocks along the water's edge.
Time needed
A standard visit for basic sightseeing and enjoying the immediate riverside environment usually takes a few hours. However, those planning extended hikes, rafting, or comprehensive nature exploration should easily allocate a full day.
