We did a hiking trip in Patagonia last March, and it was fantastic. Probably our favorite hiking trip, for scenery, terrain, lodging and food. We hiked in both Chile and Argentina. We went on a guided trip with Mountain Travel Sobek as we were able comfortable driving, and the public transport is logistically difficult. The guides and arrangements ( lodging, meals, transport) were all excellent and we felt it was worth the extra we paid over an independent trip.
I am gluten-free and the guides were very attentive to my needs, even choosing a pizza restaurant that offered gluten-free crust for one lunch. For picnics my sandwiches were always made with gluten-free bread, and it was much better bread than I can find in the US.
