Colonia del Sacramento is a small, peaceful town on the Uruguayan shore of the Río de la Plata, looking across the water to the skyline of Buenos Aires about 50 km (31 miles) away. Founded by the Portuguese in 1680 as a smuggling outpost on Spain’s doorstep, it changed hands between the two empires again and again for a century, and the result is a Barrio Histórico (historic quarter) of cobbled lanes, low tiled houses, crumbling walls and flowering bougainvillea that mixes Portuguese and Spanish styles. It has been on the UNESCO World Heritage List since 1995. Colonia is the most popular day trip from Buenos Aires, just over an hour away by fast ferry, but it’s at its best in the evening, when the day visitors leave and the sun sets over the river. Around it are a riverside promenade and beaches, a forgotten Edwardian bullring, wineries near Carmelo and Swiss-founded villages. The climate is mild, with warm summers and cool, damp winters.

Colonia’s areas: where things are
Colonia is small and easy to understand. The ferry port and bus terminal sit side by side at the edge of the modern town, about a 10-minute walk from the old town.
The Barrio Histórico
The historic quarter fills the tip of a small peninsula, surrounded on three sides by the river. Its edge on the land side is marked by the reconstructed city wall and gate, the Portón de Campo. Inside are the Plaza Mayor 25 de Mayo, the lighthouse, the basilica, a cluster of small museums, restaurants in old houses, and lanes such as the Calle de los Suspiros running down to the water.
The modern town
East of the old town, a grid of streets centered on Avenida General Flores holds shops, banks, supermarkets, mid-range hotels and the main square, Plaza 25 de Agosto. It’s a working Uruguayan town, much less touristy.
The Rambla and Real de San Carlos
A riverside promenade runs north along the shore past small beaches to Real de San Carlos, about 5 km (3 miles) away, where an Argentine entrepreneur built a resort complex in the early 20th century, including a bullring, a jai alai court and a racetrack.
A short history of Colonia
Portugal founded Colonia in 1680, directly across the river from Spanish Buenos Aires, to claim the north bank of the Río de la Plata and to trade, legally or not, with the Spanish colonies. Spain captured it within months, and over the next century the town passed back and forth between the two crowns through sieges and treaties, until it finally became Spanish in 1777. After independence, Colonia became part of Uruguay, while the port of Montevideo grew far bigger. Because Colonia was left behind by later development, its old streets survived largely intact, and the mix of Portuguese houses, with their sloping tiled roofs and stone walls, and flat-roofed Spanish buildings is what makes the historic quarter unique.
Top things to see in Colonia del Sacramento
Many of the old town’s museums are small and share opening hours, usually closing one day a week; a single ticket from the town’s museum system usually covers several of them. Check current hours and prices locally.
Portón de Campo
The old city gate, with a wooden drawbridge and a stretch of rebuilt stone wall and moat, marks the entrance to the historic quarter on its land side. It was reconstructed in the 20th century on the line of the original Portuguese fortifications.
Calle de los Suspiros
The “Street of Sighs,” a steep, cobbled lane with a drainage channel down its center, lined with low colonial houses, slopes down to the river. It’s the most photographed street in Uruguay; go early in the morning or at sunset to avoid the crowds.
The lighthouse and the San Francisco convent ruins
The white lighthouse, built in the 1850s on the ruins of a 17th-century Franciscan convent, rises from the Plaza Mayor. Climb its narrow spiral staircase, for a small fee, for a view over the rooftops, the river and, on a clear day, Buenos Aires.
Plaza Mayor 25 de Mayo
The large, tree-shaded main square of the old town, lined with historic houses, the ruins of the viceroy’s house and the Portuguese museum; it’s the natural place to start a walk.
Basílica del Santísimo Sacramento
One of the oldest churches in Uruguay, first built by the Portuguese in the late 17th century and rebuilt several times since, after fires and an explosion of gunpowder stored inside. It’s simple and whitewashed, with a quiet square in front.
The museums
The town’s museum system includes the Portuguese Museum, with furniture, maps and tiles from the Portuguese period; the Municipal Museum in a colonial house; the Casa Nacarello, a furnished 18th-century home; the Spanish Museum; the Indigenous Museum; and the Tile Museum. Each takes 15–30 minutes.
Bastión del Carmen
A cultural center in a 19th-century factory beside the river, with exhibitions, a theater and a garden facing the water, at the northern edge of the old town.
Real de San Carlos
The bullring (Plaza de Toros), opened in 1910 and closed soon after when bullfighting was banned in Uruguay, stood abandoned for decades before its restoration as a venue for events; next to it are the old jai alai court and the racetrack. Walk or cycle along the Rambla to reach it.
Other things to do
Sunset on the river
Colonia faces west across the Río de la Plata, so every evening brings a sunset over the water. Popular spots are the rocks at the end of the Calle de los Suspiros, the Bastión del Carmen, the old pier and the Rambla.
Cycling, scooters and golf carts
The town is flat and quiet, and renting a bike, scooter or golf cart is a popular way to explore the Rambla, the beaches and Real de San Carlos. Drive slowly on the cobbles and watch for pedestrians. See our guide to cycling.
Beaches
The small river beaches along the Rambla, such as Playa Ferrando and the beaches toward Real de San Carlos, are busy on summer weekends. The water is brownish river water, calm and shallow. See our guide to beaches.
Food and drink
Restaurants in the old town serve Uruguayan parrilla, homemade pasta, fresh river fish, chivitos and pizza, many with tables outdoors on the cobbles. Try the local wines from the Colonia and Carmelo area, especially Tannat, and cheeses from the Swiss and Piedmontese settler villages inland. Prices in the historic quarter are higher than in the modern town.
Day trips from Colonia
- Carmelo: a quiet river town about 75 km (47 miles) north-west, at the mouth of the Arroyo de las Vacas, surrounded by family wineries, olive groves and upscale resorts; it’s also the arrival point of river boats from Tigre near Buenos Aires. See our guide to wine tasting.
- Nueva Helvecia and Colonia Valdense: villages founded by Swiss and Piedmontese Waldensian settlers in the 19th century, about an hour east, known for cheese, dairy farms and a festive Swiss heritage.
- Conchillas: a village built by a British company in the late 19th century to quarry stone for the port of Buenos Aires, with brick houses unchanged for a century.
- Montevideo: the capital, about 2.5 hours east by bus; see our Montevideo travel guide.

Getting there and getting around
By ferry from Buenos Aires
Two companies run fast ferries across the Río de la Plata from Buenos Aires’ Puerto Madero:
- Colonia Express: sails from its terminal in Puerto Madero Sur. According to the company, the crossing takes about 1 hour 15 minutes, and in September and October 2026 boats left Buenos Aires at 8:30 and 10:30 a.m., 12:50, 6:30 and 8 p.m., and Colonia at 8:30 and 10:30 a.m., 4:30, 6 and 8:15 p.m.; a new timetable applies from November 1. Combined tickets with a connecting bus go on to Montevideo and Punta del Este.
- Buquebus: sails from its Puerto Madero terminal to Colonia several times a day, and also directly to Montevideo; it carries cars and bikes.
Both companies sell day-trip packages with lunch or a guided tour. Bring your passport: Argentine exit and Uruguayan entry are handled together at the departure terminal. Book ahead for weekends, holidays and summer, and compare the two companies’ fares, which vary a lot by time of day.
By bus
Buses connect Colonia’s terminal, next to the ferry port, with Montevideo’s Tres Cruces terminal about every hour, taking about 2.5 hours for the 177 km (110 miles), and with Carmelo and other towns in the west.
Getting around
The old town is best explored on foot, but wear shoes with good grip for the uneven cobbles. Bikes, scooters and golf carts are rented near the port and in the old town, local buses run to Real de San Carlos, and taxis wait at the terminal.

One day in Colonia
Arrive on a morning ferry, walk through the Portón de Campo to the Plaza Mayor, climb the lighthouse, visit two or three museums and the basilica, and stroll the Calle de los Suspiros. Lunch on the cobbles, then rent a bike or golf cart for the Rambla and Real de San Carlos, and catch the evening ferry after sunset.
