    Juani North is a solid pick when you're diving Mafia, especially if you’re looking for a reef that actually fringes the island. We’ve found the slope here to be pretty gentle, hitting a max of 21m, which makes it an easy dive for most skill levels. The corals lean towards those pinks and purples, giving the reef a distinct tone. Keep an eye out for green turtles – we often spot a few cruising by. You'll likely encounter the usual reef fish schools too, with giant trevallies occasionally making an appearance. Visibility averages around 13m, so it’s not always gin-clear, but good enough to appreciate the details.
