It is fun, cool little cave. Sitting on the boat in total darkness was a cool experience. But you are obviously being ripped off. $75 per person, another $30 if you want a photo (while the framing was good, the photographers were pretty bad at it), the cost is steep for a short walk in a cave. Having said that, no regrets, it is a good activity for a stop over in Te Anau to break the trip to Milford Sound into 2 days rather than rush it.
