Dive-site story
Southwest Pinnacle is one of the premier offshore sites around Koh Tao, consisting of a series of granite seamounts anchored on an open sandy seabed. Massive carpet anemones blanket the shallower rock crests, bustling with pink anemonefish. Further down the granite flanks, large predatory fish patrol the open blue, making it a reliable spot for encounters with schooling pelagics and passing giants.
