The irony of visiting a botanical garden in Buenos Aires - possibly the greenest city I've ever…read morebeen in - was not lost on me. It most certainly is not a must-do experience as, if you walk there from wherever, you're likely to pass so many expansive, grassy, tree-filled parks that you'll question why you're not just stopping now.
I'm actually a much bigger fan of green parks than botanic gardens (even free ones like this) as I generally care little about plant species or origins. But I came here and found it to be a nice experience. Ample benches in the shade of trees provide a nice spot to hang out and many were doing just that. I spotted a couple sitting on a bench reading actual paperback books and thought "my tribe" before I noticed that I was feeling things bite me ever so often as I strolled through.
So I'm probably not hanging out here for long.
There were several places that should have held water (ponds, I guess) but they were, sorrowfully, dry on this visit. I do like a water feature. There's also statues and greenhouses (not open to visitors).
There's absolutely no reason to head here but if you do, it's a nice place to stroll through on your way to, perhaps, areas with more grass and fewer insects.
