An hour from the Obelisco, the city dissolves into 14,000 square kilometres of islands and brown channels: varnished wooden launches, stilt houses, floating grocery boats, riverside beer gardens and quiet arroyos where capybaras graze.
The Paraná delta is one of the largest in the world, a maze of willow-lined channels where islanders live in houses on stilts and everything, from schoolchildren to groceries, travels by boat.
From the Tigre fluvial station, wooden lanchas colectivas run out to the islands past rowing clubs, stilt houses and floating grocery boats. Get off at a recreo, a riverside garden with a restaurant and a beach, for lunch and a swim, or join a guided kayak trip into smaller arroyos where capybaras and kingfishers live.
Back in town, the Puerto de Frutos craft market and the Museo de Arte Tigre, housed in a Belle Époque casino on the river, fill the rest of the day. The Mitre line from Retiro is the cheap route, and the Tren de la Costa from Maipú is the scenic one. Weekends are busy with porteños doing the same thing.
On the way, two smaller riverside reserves, Ribera Norte in Acassuso and the Vicente López reserve, protect marsh birds and the only sand on the city's river. Combine either with the Tigre day.
Leave early to beat the weekend crowds and stay on the water through lunch.
Take the Mitre line to Tigre, or change at Maipú for the Tren de la Costa along the riverside suburbs.
Hop off at Acassuso for an hour's boardwalk birding at Ribera Norte before continuing.
Buy a ticket for a colectiva launch along the Sarmiento or Capitán rivers, and pick a recreo to stop at.
Asado or milanesa under the trees, a swim from the jetty, a siesta in a deckchair. Or paddle the arroyos by kayak.
Back in town, browse the Puerto de Frutos and visit the Museo de Arte Tigre before the train home.
Pay with a SUBE card on the Mitre line; the Tren de la Costa charges a separate tourist fare.
Several companies run lanchas colectivas from the fluvial station; ask for a return ticket and the timetable back.
Book guided kayak trips a day ahead; they include safety gear and a guide who knows the arroyos.
