The Huemul glacier is a nice little hike near the town of El Chalten, in the Patagonia region of Argentina.
I did this hike recently and really enjoyed it! It’s short, easy, and relatively inexpensive, and you get to see some nice mountains, a glacier, and a bright blue lake.
It’s a great way to spend a rest day between bigger hikes like Fitz Roy and Laguna Torre, and most people visiting El Chalten don’t know about this spot yet, so it’s still a bit of a hidden gem.
