My wife & I are going to be in Franz Josef on 4th Jan '14 (arrive on 3rd evening) and then drive to Wanaka the next day. We'll do either the Ice Explorer or Heli Hike on FJG on 4th Jan.
We wanted to see Lake Matheson as well. As I understand, the best time to visit is the morning. Is it possible to do that on the 5th, on our way to Wanaka? I read in one of the threads that the walk at Lake Matheson takes 3.5 hours; so does the drive to Wanaka. What time should we ideally start from Franz Josef?
