There are 2 shark dive areas in Fiji, and they can be found in many areas. In Beqa Lagoon there are 2 operators that do the shark dives (Aqua Trek and Beqa Adventure Divers). Both are excellent operators. In either case they take frozen chum down and feed the sharks while divers are in the water. I’ve done the shark dive several times with both operators and have never felt myself to be threatened or in any danger. Both have excellent safety records. Of the 2 shark dive areas, Beqa is the more ‘active’ and exciting. The other area is a site in the Mamanucas called The Supermarket. They no longer feed there, but the sharks still come in regularly. I found that to be a more relaxed experience that still offers a great shark experience. Beqa, however, boasts a wider variety of sharks (as many as 8 different species, sometimes all on the same dive!). I’m not a fan of feeding to bring sharks in so I don’t make it a point of doing the dive often, but it is a unique experience that I’d recommend doing at least once.
