We had a good day and got to see the Glow Worm Caves. Please note that you cannot take any pictures inside the caves. I'm not sure what I expected, but I was surprised to find that the glow worms, which are very tiny, are essentially like glowing dots of green on the ceiling of the caves. We had a good local guide who explained everything to us. It is dark and cool inside the caves. The walls are made of limestone and there are many stalagmites and stalactites. Cruise passengers get a slightly abbreviated tour of the cave area due to time constraints. We visited in the morning, only to find that the worms glow more brightly later in the day.
We also visited a redwood tree forest, but didn't have time for the 45-minutes tour that involves climbing a ladder up into the trees and walking along swinging bridges. We just had 20 minutes at that stop so you just wander around a bit and admire the tall, reddish trees in a cool forest. We also saw Haruru Falls. Very pretty--not too large. You enter at the top of the falls, rather than below.
We had a lunch stop (it was okay) and then visited a chocolate shop. They gave out very small samples, but most had nuts. My husband can't eat nuts, so he didn't get much to taste. Prices for the chocolates are high. We then went next door to a shop that sells beautiful wooden pieces, but those prices were even higher. No bargains here, but really pretty merchandise.
We had a photo stop on the way back to the ship with a view of the lovely hillside and New Zealand's version of a Christmas tree, with red blooms that only flower for a few weeks before Christmas. As an American from the Northeast, it's hard to get used to the idea of Christmas in summertime with such warm weather. There's no dreaming of a white Christmas in this part of the world. The flowers and fresh fruits were a nice addition, though.
