Today it rests upright on a sandy seabed in clear waters, encrusted with colourful sponges, soft corals, and gorgonian fans. Snorkelers can explore the upper deck and superstructure from the surface, while divers follow an interpretive trail past remnant shellfire scars, seeing how the wreck has transformed into a thriving marine habitat.
