Please note: You CANNOT reach Deep Cove by car (unless your car also doubles as a submarine). The unsealed road between the West Arm of Lake Manapouri (where the power house is situated) and Deep Cove was built as part of the power station project. It does not connect with any other road. (All supplies to West Arm were barged in from Manapouri or came over the road from Deep Cove.)
Dont shortchange yourself on time for Milford Sound and environs. I could easily spend weeks on the road between Te Anau and Milford - there are many side trips/day walks/photographic opportunities that are worth exploring - and that's without spending time at Milford itself. Milford may be busy during the day (when all the tourist buses are on the scene) but you'll find it reasonably quiet after they depart (assuming you have your own campervan). And when the light is at its best for taking photos you may find yourself all alone ... :-)2)
We will probably visit also the Milford Sound, though I expect this place to be rather full and that is not what I am after - so we will probably only go for 1 day driving trip.
One last word of advice: dont forget your insect repellant. The sandflies at Milford (well all of Fiordland actually) are amongst the most tenacious you will encounter ...
Hope this helps
Cheers
