Discovery World Aquarium

If you're not swimming among the fish, or eating the fish, you might considering paying a visit to the fish in the Discovery World Aquarium, which is a reasonably entertaining rainy-day outing. The highlight is the 44m 'tunnel', which allows you to walk right through the reef and be surrounded by sea creatures on all sides. In addition to the 13 ocean aquariums, there's a fresh-water exhibit, complete with waterfall.
