The photos in this album relate to islands of Koh Larn and Koh Sak. Koh Larn is the largest of the "Near Islands", off south Pattaya. It is located at the SE end of the Bay of Bangkok, on the eastern side of the Gulf of Siam. Koh Larn lies 8 km away from the nearest shore and it is about 4 km in length. It is a hilly island, covered with low tropical forest; its highest point reaches 205 m. Koh Sak is a narrow "C" shaped island with a small bay open towards the north. It is located 0.6 km off Koh Larn's northern tip. Highest point is 33m. It has a horseshoe-shaped beach in the north. Thailand has some reefs and a number of shipwrecks. The under sea visibility in some places of Thailand is up to 30 metres with coral gardens, undersea rock formations, hard and soft corals, whale sharks, silvertip sharks, manta rays and shipwrecks. In reality, visibility is often less depending on a number of unpredictable factors such as winds, tides, currents, runoff from rain, proximity to cities, water temperature, underwater activities and more.
