Tandil...great for hiking in the province of Buenos Aires, and a wonderful place to escape Bs As for a weekend.Haha I'm not sure I'm so adventurous, but short of relocating to El Chalten, I was curious if there was a 'hiking spot'. In NYC you could jump on the train and go a couple hours north to hiking (and obviously that's a big city too). I lived there for a decade before I realized it was possible on public transportation, which is why I ask. Always nice to have a change of scenery!
