The Best Dive Sites

Similan Islands of Thailand National Park and Richelieu Rock offer the best diving in Thailand. You will appreciate the unique visibility, diversity of inhabitants and the picturesque underwater landscape. In the vicinity of Phuket Island, you will find excellent diving sites for both experienced divers and beginners. Such as King Cruiser Wreck, Shark Point, Koh Racha Ya islands and Koh Racha Noi. Koh Tao island is entirely devoted to scuba diving. The cost of diving is much lower here than in other areas of the country.

Health & Safety

Health care in Thailand is well-developed, but also costs a lot, so it is better to purchase your travel insurance before the trip. There is no obligatory list of vaccinations to enter the country. But if you are planning an extreme vacation, experienced travelers recommend to be vaccinated against typhoid, hepatitis A and B, diphtheria, rabies, tetanus, and if you travel from April to October, then also from Japanese encephalitis. Thailand is a safe country, with a low crime rate. There is special "tourist police", and if you get into a tricky situation, you can ask them for help.

Dangerous Marine Life

Dangerous marine life lurks in the coastal waters of Thailand. Every diver is taught how to behave when meeting a potentially dangerous sea creature. Here you can spot a great variety of fish: triggerfish, moray eels, sea snakes, pterois, shorthorn sculpins, reef stonefishes, and in some places even several species of sharks. Do not touch sea creatures, especially sea urchins and jellyfish, as well as coral bushes and overgrown wreck walls, because you never know, what can be hiding there.

Eat & Drinks

After spectacular scuba diving you can also dive into the culinary art of Thailand. Traditional Thai breakfast consists of thin white rice noodles. It is called Khanom chin and it is usually served with various curries — spicy fish, crab, sometimes even chicken. Soup with yellow noodles and pork will be offered to you for lunch. Another popular dish is kaeng — minced pork wrapped in soy paper. Loba — a stewed pork offal dish, is popular as an appetizer. The most common soft drink — fresh fruit juice. The most famous Thai dish is Tom Yam soup with lots of shrimps and mushrooms, which are cooked with coconut milk. Since tap water here may be unsafe to drink, it is advisable to consume only bottled water.
