Maarehaa Kandu is an advanced boat-only channel dive on the eastern rim of Huvadhoo, where the outer wall, ledges, and channel mouth concentrate pelagic life. The site is widely described as a protected no-fishing pass, and when guides catch the right incoming flow, divers settle onto the edge to watch grey reef sharks, silvertips, eagle rays, jacks, and tuna moving through the blue. The dive is less about covering distance than timing the current and reading the channel. Expect a drift-oriented plan, open-water exposure at the mouth, and a finish that can slide into sandier sections with turtles, stingrays, fusiliers, and hard-coral patches inside the channel.
