Rotorua is known for it’s volcanic activity. Call me a bit blasé, but I have seen much better. Having visited Iceland and Japan, New Zealand is really not that impressive. Also they try to profit from every little thing they can. It sucks the fun out of it. I found this nice place where you could swim for free in the forest. That was cool, but not warm enough. haha
Here are some pictures of The city and the surroundings of Rotorua.
