This post is an FYI of the basics involved in my trip backpacking patagonia, in case you want to plan a similar trip yourself. There is as much information on costs and simple logistics here as I can remember, although no doubt I've missed something so take it as an approximate. If you are looking to plan anything in the areas I visited and would like more detailed information, don't hesitate to message and I'll happily help in any way I can.
