Jina Wall suits divers who like a wall profile, close grouper encounters, and tide-aware boat planning outside Mafia's sheltered bay.
About Jina Wall
Jina Wall is a Mafia Island wall dive on the northern tip of Jina Island, with shallow caverns, overhangs, and a gravel base. The signature encounter is a very large potato grouper that often comes close, while pelagics, schools of fish, and rays can appear in the blue. It is a better fit for divers who are comfortable on a wall profile and who time the dive around the tide.

Local Intel For Jina Wall
Community notes to help plan your visit.
Scuba Diving
Depth range is 8–26 m along a vertical wall with shallow caverns and overhangs, finishing over a gravel field.
Freediving
Potentially workable for experienced freedivers on calm tide windows, but the wall, overhangs, and current make the site more comfortable with a proper boat plan.
Snorkeling
Not a primary snorkel site; the wall structure and tide-sensitive edge are better handled with scuba or a very controlled freedive plan.
