The Argentine glaciers are among the few remaining, largely untouched, natural wonders of the world. They are amazing and awe-inspiring to see and to imagine what it must have been like when much of the world was covered in glaciers.
Unluckely now is not avalaible at the tour ( september 2015 ), only spegazzini and upsala, the trip is great. Im not sure if this trip is better than Perito moreno, but is amazing.
Do it. Ornelly is bloqued.
