The Lake District area of Argentina really is beautiful. Not quite as dramatic as down in Patagonia or as mind-blowing as that in Peru, but a for pure picture-perfect countryside that you could imagine a couple of hobbits living out their days in its hard to beat.
I found in particular the Chico Circuit by Bariloche a fantastic experience (details – Cycling and drinking craft beers around the Chico Circuit in Bariloche), but for the famous Seven Lakes route from Villa la Angostura to San Martin de los Andes I was unfortunately a bit underwhelmed. It’s probably because our expectations were so high after seeing the wonders in this part of the world, but either way we found ourselves less having an amazing experience and more just having a pleasant drive.
For sure this would be a great place to completely relax for a few days, enjoy the scenery by one of the lakes and go for some easy walks through the forest, and I would stress that Bariolche and its immediate surroundings are a highlight of this part of the world, but I wouldn’t go out of your way to make the drive from Villa la Angostura to San Martin de los Andes.
