Millions of vacationing tourists visit Hawaii every year. Most of them came to explore the beautiful Hawaiian Islands and volcanoes while some came with the intention to scuba dive in the tropical seas and to explore Hawaii's magnificent underwater world. According to Rodale's scuba diver magazine, Hawaii is one of the world's top ten diving destination for scuba divers.

Hawaii's marine life is very diverse so much so that there are more than a hundred endemic species found no where else on earth. You can explore Hawaii's myriads of underwater caverns, reefs, drop off walls, canyons, gulleys and swim with turtles and seals in clear crystal waters. If you are not a scuba diver, you can take scuba diving lessons and then can plunge into Hawaii's beautiful seas almost immediately.

If you want to go scuba diving, it is best to go in the morning as strong winds often rough up the sea in the afternoons. This is especially so on the island of Maui and that is the reason why dive operators often take divers out to sea early in the morning and terminate the dives around noon or early afternoons.

One of the big attractions in Hawaii is snorkeling. Almost anyone can go snorkeling since all you need is a face mask, a snorkel tube and a pair of swimming fins. If you have never snorkeled before, most resorts and dive operators can give you snorkelling lessons and rent you snorkeling gear. However, if you can swim, you really do not need any formal training as snorkeling is quite easy.

The most popular spot for snorkeling in Hawaii, especially for the beginner is the Hanauma Bay, on the island of Oahu. Other popular snorkeling sites in Hawaii are the Kee Beach on Kauai island, Hulopoe Bay in Lanai, Kahaluu Beach on the Big island and Kapalua Bay on Maui.

Although great snorkeling can be gotten at all the islands in Hawaii, snorkeling and scuba diving on the Big Island is recommended because of its volcanic activities and lava formation resulting from that. There are magnificent and spectacular drop offs with awesome underwater scenery to watch and admire. Some of the great snorkeling locations there are Molokini Crater and the Kealakekua Bay.

Whether you are snorkelling or scuba diving in Hawaii or anywhere else, always snorkel or dive with a buddy for safety reason and companion sake. Do look up now and then to check that you are not getting carried away by drift current too far away from shore and also to check for boat traffic. Do not touch anything as some corals and sea creatures in Hawaii can pack very painful and venomous stings.
