Waikiki - Oahu Underwater Cruises

The reefs around Oahu are deep and have suffered damage both through human activities and tropical storms. Some efforts have been made to sink ships and planes as way of giving the reef and the colorful fishes some protective places to grow.

Submarines are the only way to see some of the interesting underwater life of the area and such trips are rewarding. On rare occasion whales have examined the submarines which are smaller than these mammals.

There are competing companies for such excursions.
