Thailand is widely regarded as one of the world's premier scuba diving destinations, offering a perfect blend of spectacular marine life, diverse underwater landscapes, and exceptional value. The country is split into two distinct diving regions: the Andaman Sea to the west and the Gulf of Thailand to the east. The Andaman Sea is home to Thailand's most famous sites, including the world-renowned Similan Islands and the legendary Richelieu Rock, famous for its frequent whale shark sightings and vibrant purple soft corals. Here, divers can explore dramatic granite boulders, deep drop-offs, and thriving coral reefs teeming with life. In the Gulf of Thailand, the island of Koh Tao has become a global hub for dive training, offering easy conditions and a wealth of sites perfect for both beginners and advanced divers seeking to encounter whale sharks at sites like Chumphon Pinnacle. Thailand's diving infrastructure is world-class, ranging from luxury liveaboards that traverse the remote northern Andaman to budget-friendly dive schools on the islands. With warm water, excellent visibility, and a hospitality culture that is second to none, Thailand provides an unforgettable underwater adventure for every level of diver, whether they are looking for high-voltage pelagic action or the intricate beauty of macro life.

Thailand is one of the world's best-value destinations for liveaboard diving. The majority of trips operate in the Andaman Sea, departing from Khao Lak or Phuket to explore the Similan Islands, Surin Islands, and Richelieu Rock. These itineraries typically range from 4 to 7 nights and offer the best way to experience these remote and pristine sites. Liveaboards in Thailand cater to all budgets, from simple, communal-style boats to high-end luxury vessels with en-suite cabins. For those with less time, shorter 2 or 3-night trips are also available, providing a fantastic introduction to the northern Andaman's spectacular underwater world.

Thailand has an extensive and very affordable transport network. Domestic flights connect all major cities and tourist hubs. An efficient railway system runs between the north and south, while buses and minivans reach almost every town. For the islands, a reliable network of ferries and speedboats operates daily. Within cities, options range from Bangkok's modern BTS SkyTrain and MRT to the iconic tuk-tuks and ubiquitous motorbike taxis. Renting a scooter is common on the islands but requires caution and an international driving permit.
