Marimbani
Shallow sandbank muck dive with tide timing and picnic-style boat access.
Local operator required
A local Mafia Island operator is the practical way to time the tide, boat, and lunch plan.
Mafia Island sandbank dive in Chole Bay with a shallow muck patch on the northern face, best planned around the tide window and easy to combine with a snorkel or lunch stop.
About Marimbani
Marimbani is a tide-shaped sandbank in Chole Bay with a shallow muck-diving patch off the northern face of the sandbar. The site changes character with the tide, so timing the boat ride around the low-water window matters. Divers and snorkelers come here for sandy-bottom macro hunting, calm-water planning, and the chance to finish with time on the exposed sandbank or a relaxed picnic stop.
