As you can see by this map of Koh Samet, the oil spill hit Phrao Bay on the western side of the island. There are only a few resorts on this beach which are popular with more upmarket tourists. The majority of Thai and foreign tourists that head to Koh Samet stay on the east coast which has the best beaches. Thai media in Phrao Bay last night said that tourists have started to check out of their rooms. However, most have just switched to the eastern side of the island which is clear from the oil spill. The latest satellite image this morning shows the oil spill already moving away from the island. This is obviously good news for the resorts on the eastern side of the island but not so much for the beaches on the mainland in Rayong.
