Ko Similan
Ko Similan or Island 8 is the largest island in the chain. The average depth of the waters around Similan Island is about 25 meters. Ko Similan has a very small bay look like horseshoes on the western side with the average depth of 60 feet where spiny lobsters rest in crevices and sea fans, plume worms and soft corals sway to the current. Above the sea, lies the huge symbolic rock of Ko Similan and its worth the hike to the top to enjoy a sweeping view of the sea.
