I will be traveling in Aug and will like some advises on my plans as follows:
D1 Arrive Christchurch in morning
Drive to Punakaiki via Arthur's Pass
D2. Drive to Fox Glacier with stopover in Franz Josef
D3. Morning helihike in Fox's Glacier
Drive to Wanaka with stopover in Lake Matheson
D4. Morning visit to Puzzling World
Drive to Te Anau
Tour of glow worm cave
D5. Drive or tour from Te Anau to Milford Sound
Is D3 rushing as I don't think I am able to make it for the helihike in D2?
Should I stay another night in Fox? However, there isn't much else to see in Fox if I opt for an additional night.
On D4, will there be time to do the glow worm cave tour upon reaching Te Anau and checking in?
