I've been out of town all week and saw I got a few responses. I included some more information with the pictures I posted. It was an awesome trip. I took those pictures with a simple digital camera. The trip consisted of spending a few days in small towns or villages and day hiking at each location. A few days were spent driving to different national parks in Argentina and Chile. A person could easily make a week long trip of staying in El Chalten and doing several day hikes in the area. Hiking/camping permits are not required, but that will probably change within the next few years.
