Carreterra Austral and Lake region in Chile
 

Hello,am planning to drive the Carreterra Austral in March'19 from Puerto Montt to Villa O'Higgins but then need help from anyone who has done that trip please.
Should I drive back to Puerto Montt from Villa O'Higgins?(I have already visited the Torres Del Paine region in the past,therefore do not want to take the ferry to Puerto Natales)and then visit the lake region North of Puerto Montt?
There doesn't seem to be any ferry between Villa O'Higgins to Puerto Montt,and would be really appreciative for any advice in the area.
I've got 3 weeks in the area.
Thank you all.
