Vattaru Kandu

Felidhoo · Vaavu Atoll · Maldives

Vattaru Kandu is a deep channel slicing through the western rim of Vaavu Atoll, one of the Maldives' less-visited atolls despite offering some of the archipelago's finest channel diving. The kandu faces the open Indian Ocean to the west, and when the northeast monsoon drives water into the atoll from January through April, the channel becomes a funnel concentrating everything the open ocean sends: nutrients, plankton, and the predators that follow both. The dive is a drift, initiated by a negative entry into the current at the channel's outer edge. Descending to twenty-five metres on the northern wall, the channel stretches ahead as a blue corridor flanked by coral-encrusted walls. The current pushes steadily inward, and within moments the first grey reef sharks appear: a pair cruising the wall edge, then five more in loose formation behind. By the time the drift has covered fifty metres, the sharks are everywhere, a gathering of thirty or more grey reef sharks holding position in the current with economical fin movements. The sharks at Vattaru behave with the confidence of an unpressured population. They hold station at the channel entrance, facing into the current, occasionally breaking formation to investigate something in the water column before returning to position. Their density here creates a wall of grey bodies that divers drift past at arm's length, an experience that is simultaneously thrilling and strangely calming in its naturalness. Eagle rays exploit the same current. Squadrons of up to twenty spotted eagle rays pass through the channel in disciplined V-formations, their diamond-shaped bodies undulating with synchronized precision. They appear from the blue beyond the sharks, traverse the channel width, and disappear into the atoll interior. The channel walls reward attention between pelagic passes. Overhangs at twenty to thirty metres shelter gardens of soft coral in purple and orange, with sea fans extending from the wall face into the current. Napoleon wrasses of exceptional size cruise these overhangs, and whitetip reef sharks rest on ledges, indifferent to the river of current and divers passing above.
