Can anyone please offer any opinions on the differences between the glow worm experience at Te Anau versus that at Waitomo? I'm wondering more about the "wow" factor of the glow worms, rather than the geology of the caves.
I'm focusing on the South Island for this trip and only have 12 full days. But I will be spending the last day or two in or around Auckland. Otherwise, I wasn't planning anything else on the North Island for this trip, unless it is worth going out of my way to see Waitomo? If Te Anau is just as good or better for the bioluminescent experience, that would be ideal because I'll be in that area anyway. But I'm willing to consider a side trip to Waitomo if it is significantly better.
Thanks for any suggestions!
