You should be careful with the food from food stalls or in simple restaurants. Eat only things that have been thoroughly cooked and are served really hot. The large amounts of chili that are part of nearly every Thai dish may have a disinfecting effect, but you should not rely on this! Vaccinations against tetanus, hepatitis, and salmonella
infections are generally advisable.
Sunrise at Lamai Beach
Thailand is generally considered a safe country and for tourists, Koh Samui is very safe place with no open violence in the streets. There is probably criminality, but it is unlikely that you will encounter it. The worst that could happen to you is probably that you get pick pocketed or that a tout tries to take you to a shopping center. These people often wait in front of temples or museums and tell you that they are closed. Guess what they suggest you should do instead? Right, visit a jewellery shop - or a handicraft store... Just ignore them. If the temple happens to be really closed, you can come back and get a taxi or a songthaew then. Always refuse when somebody offers you a free tour at tourist attractions As everywhere, of course, it is better to avoid carrying large amounts of cash, credit cards or traveler's cheques are preferable.
