There are few better ways to spend a rainy day in Auckland than at the aquarium. Situated right on the water, overlooking the harbor, the aquarium houses over 30 animal exhibits. With everything from sharks, to octopus, to, of course, penguins (!), there's so much to see, making it the perfect family excursion. And if you are looking for something a little more adventurous, try the shark cage! You are placed in a cage in one of the underwater exhibits filed with blue sharks, letting you get really up close and personal with the fascinating creatures. Make sure to buy your tickets online in advance, as the prices are much less ($31 for a single admission online versus $39 at the door). If you are looking for a different way to spend your time in Auckland, the aquarium is a definite must!
