Dive-site story
Located off the coast of Pulau Weh, this geothermal dive site features active underwater vents where curtains of sulfurous gas bubbles continuously stream up through dark sand and volcanic rock. While dense coral formations are absent directly around the vents, the surrounding seabed is warmed by thermal activity and dusted with mineral deposits, creating an unusual underwater landscape contrasting with the island's typical reef drop-offs.
