Drive from Queenstown to Milford Sound
Avoid the expensive bus tickets and drive the 300km yourself to one of New Zealand's most impressive sceneries. The sights on the way and the hikes around the fiord are almost as impressive as Milford Sound itself.
You'll have to book the 1-2 hour cruise in advance if you want to take a close look at the cliffs and waterfalls.
Make sure you have a full tank, don't be counting on finding a gas station on the way.
Be careful if there was heavy rain recently as there might be landslides or floods blocking the way.. Experience New Zealand like a local and have fun in undefined with like-minded people.
