Advice Chilean Patagonia

Hola! 

I'm currenty in the North of Chile finishing off a work placement and trying to speak Spanish very badly! 

I go to Chilean Patagonia (fly to Punta Arenas) at the end of May and have a period of about 6 weeks to see as much and do as much as possible.  I was wondering if anyone had any words of wisdom they would be willing to pass on.

I am hoping to do alot ski touring/hiking/climbing etc but would like to go slightly off the beaten track. 

Any advice would be much appreciated! 

All the best 

Heather
