Shallow Mafia reef with turtles and drift current.
Use a local Mafia Island boat and guide; the site is handled as an outside-bay drift dive.
Kasa is a shallow Mafia Island reef for divers who want bright coral, seagrass, and turtle action more than a big-depth profile. It is often dived as an outside-bay drift, so the site can feel more exposed than its shallow profile suggests. Expect green turtles grazing in the seagrass, with hawksbills and other reef life around the drop. It is best approached with a local boat and a careful look at current and season.

Scuba Diving
Shallow, colorful reef diving with turtle grazing and drift windows; still needs respect when the current is moving.
Freediving
Possible for experienced freedivers on calm days, but the current and outside-bay exposure make it a careful choice.
Snorkeling
Worth considering for snorkeling when the water is calm because the reef is shallow and colorful, but local advice matters on current days.
