Local Intel For Nagannu North
Community notes to help plan your visit.
Scuba Diving
Best as a guided boat dive along the reef edge and drop-off, with room for coral scenery and passing pelagics.
Freediving
Not a primary freedive site; the profile and boat logistics make scuba the better fit.
Snorkeling
The shallow reef margin may be visible on calm days, but Nagannu North is mainly a scuba and drift-oriented site rather than a snorkel-first stop.
