Snorkeling and scuba diving are popular activities sports. Kapalua Bay was our favorite and it's considered to be one of the safest areas with its protected reef. Reef fish could be seen in just a few feet of water.
Pick up a free Maui Dive Guide at one of the local dive shops. The maps are great and indicate the best snorkel/dive areas on the island including the suggested level of experience. There is also a guide to Hawaiian reef fish frequently seen.
Species we encountered include: moorish idol, parrotfish, white spotted puffers, triggerfish, wrasse, Hawaiian sergeant, moray eel, butterflyfish.
Equipment: A disposal waterproof/underwater camera. I usually purchase these on the mainland at a drug store before visiting the islands.
I'd guess a large percentage of people visiting Kapalua are here for one thing only, to play golf! It has 3 championship courses each with a clubhouse, pro shop & restaurant. Millions of TV viewers have watched Kapalua golf via worldwide telecasts of pro tournaments like the Mercedes Championship.
