Dive-site story
Rubiah Sea Garden sits directly across the narrow channel from Iboih Beach on Pulau Weh, protected within the Rubiah Island marine sanctuary. The underwater landscape features sprawling fields of branching hard corals, massive Porites bommies, and shallow table corals that transition into a gently sloping sand bottom. Because water movement remains relatively gentle inside the bay, it serves as a favored spot for relaxed daytime exploration and macro-focused night dives.
Extensive hard coral structures offering shelter to resident honeycomb moray eels and lionfish
Sheltered conditions with minimal drift, suitable for long, relaxed bottom times
Macro finds including colorful nudibranchs, banded cleaner shrimp, and flatworms across the reef substrate
