Shallow Mafia Island macro shore dive with seagrass and seahorses.
The shore window is organized by the local dive team and depends on the tide.
Tom's Garden on Mafia Island is a shallow macro-focused shore dive with seagrass, sandy patches, and a low-relief seabed that is easy to read underwater. It is known for seahorse sightings and other small critters, and the site also rewards patient divers with frogfish, pipefish, shrimp, nudibranchs, goatfish, and the occasional crocodile fish. The best dives are tide-aware and calm, with the shore window organized by the local dive team.
Safety Notes
Watch the tide window, keep buoyancy gentle over the seagrass and sand patches, and avoid damaging the macro habitat.
Access Restrictions
Shore access is tide-dependent; follow the local dive team's timing and route.
Legal Notes
Handle the seagrass and sandy habitat gently and follow the marine park brief.
