Agree with mikevdb that car is best due to distance. Helitours are good but expensive and we found we had to prioritise where to do them but of course depends on your budget. Doubtful sound is very beautiful. We did overnight cruise but had to book a fair way out. You can read my review on this and Bailiez Cafe Te Anau.
