I went with my old man up a mountain near Milford Sound a while ago. Heres a few pictures I saved:
Starts off at Homer Hut, on the Gertrude Valley.
Then we got up to 'Black Lake'. I went for a swim in that iceberg ridden lake! The middle pic above is at Gertrude Saddle looking out to Milford.
It got quite steep! The mountain in the background at the sea is Mitre Peak.
At the top! Looking out to milford, and my father overlooking Lake Adelade
