Escape Buenos Aires: Delta to Uruguay
Buenos Aires sits on flat pampas at the edge of a giant river, which means every real day trip out of the city goes one of two ways: onto the water, or into the grassland. Here’s what each option actually involves.
Tigre and the Paraná Delta
Take the electric Mitre Line train (Tigre branch) from Retiro station, it departs every 15 minutes, takes about 55 minutes, and costs roughly ARS 887 on a SUBE card. Once you’re there, board a public commuter water taxi (lancha colectiva, ARS 3,000-5,000) or a panoramic catamaran cruise (ARS 15,000-20,000, about US$12-15 for an hour) through the maze of channels. Puerto de Frutos, the riverside crafts and wicker market, is the main draw on land, along with the waterfront Paseo Victorica and the Belle Époque Museo de Arte Tigre, housed in a 1912 casino building. There is no whitewater here, the delta is flat and slow-moving, which is exactly what makes it pleasant to paddle or cruise.
Colonia del Sacramento, Uruguay
This is an international trip, so bring a passport. Fast catamarans cross the river in about 75 minutes: Buquebus departs from the Puerto Madero terminal, Colonia Express from Dársena Sur, with return fares from roughly US$50-95 depending on operator and season. Colonia’s old town, cobbled Calle de los Suspiros, whitewashed colonial houses, a 19th-century lighthouse, is a UNESCO World Heritage Site dating to 1680. Clear joint Argentine/Uruguayan immigration at the terminal before boarding, not on arrival.
San Antonio de Areco: gaucho country
About 115 km northwest of the city (1.5-2 hours by car, or bus from Retiro via Chevallier), San Antonio de Areco is the real cradle of Argentine gaucho tradition, the setting for Ricardo Güiraldes’ novel Don Segundo Sombra. Visit the Museo Gauchesco Ricardo Güiraldes and the silversmith workshops around Plaza Ruiz de Arellano, or book a día de campo at a working estancia like Estancia El Ombú de Areco for horseback riding, a gaucho horsemanship demonstration, and an asado with Malbec, figure US$80-120 per person, pre-booked.
La Plata
Argentina’s meticulously planned provincial capital sits 56 km southeast, reachable on the Roca electric train from Plaza Constitución in about an hour for around ARS 500. The neo-Gothic Catedral de La Plata is free to enter (tower elevator around ARS 3,000), and the Museo de La Plata holds genuinely impressive glyptodont and megatherium fossils for roughly ARS 4,000.
All four of these are day trips in the literal sense, out and back the same day. If you’d rather turn the delta and the pampas into an overnight loop, see the multi-day trips page . To book the Colonia ferry or a Tigre boat tour directly, check Viator’s Buenos Aires day trips or GetYourGuide . For San Antonio de Areco, a rental car from discovercars.com can be worth it if you’re skipping the organized estancia transfer and driving RN 8 yourself.
