Molokini crater is an excellent dive location. While there are many dive site's near the crater to choose from, my favorite is mid-reef. At depths of 75 feet, you can see Garden Eels swaying in the water. What a sight! There are lots and lots of colorful reef fish, eels, Cornet fish, White Tip Reef Sharks (very docile), and an occasional Manta Ray, Eagle Ray, an endangered Hawksbill Turtle...or if you are very lucky...Humpback whales or a rare Whale shark. Unlike nearby Maui shore dives, underwater visibility at the crater ranges from 100 to 160 feet. Simply incredible.
See Heart Rock too:
Although the rounded edges of this rock cavity seem almost too symmetrical to be natural, this heart-shaped window was created by Mother Nature. Pounding surf naturally eroded the lava rock shelf, eventually wearing it away until a perfect heart was formed… which means someday the ocean will force it into a new shape, so take in the views while you can. Adjacent to the Nakalele Blowhole, the hike to this natural wonder is no easy feat -- covered shoes are recommended when scaling the rocky slope, and please heed the hand-painted warning signs, and don’t stand too close to the geyser. Seriously, you wouldn’t want to get swept away in all the excitement and get, well, swept away.
