Manuelita

Manuelita is the islet guarding Chatham Bay and the closest thing Cocos has to a house reef - which at Cocos means hammerheads over the deep side by day and one of diving's great spectacles after dark. On the night dive, hundreds of whitetip reef sharks pour over the coral garden in a hunting wave, shouldering into crevices after sleeping fish while divers' lights track the melee. Tiger sharks, now regular at Cocos, cruise Manuelita's sand edge often enough that guides brief for them as a matter of course. The shallow garden also serves as the trip's gentlest dive, thick with morays and marbled rays.
