Juani Island reef slope with turtles and coral.
Juani Island reef slope with turtles and coral.
The site is best handled with a local operator because procedures can be difficult and conditions change with tide and weather.
Juani North is a fringing reef slope on the seaward side of Juani Island in Mafia. The site is known for its soft-coral colour, coral structure, and regular turtle sightings, but it can be demanding and is best handled with a local operator. Expect a sloping reef with rock and coral formations, large reef rays, schools of fish, and smaller reef life tucked into the cracks. This is a warm-water boat dive for divers who are comfortable with changing conditions and a more serious reef profile.

Scuba Diving
Boat-based reef slope diving with coral structure, turtles, and a strong tidal plan.

Snorkeling
Not a casual snorkel stop; the boat approach and changing conditions make it a scuba site first.
