Explore Thailand

Diving in Thailand offers a diverse and captivating underwater experience, making it a premier destination for divers worldwide. The country's diving scene is largely centered around the Andaman Sea, particularly on the eastern coast, where crystal-clear, warm waters reveal vibrant reefs teeming with hard and soft corals. These underwater gardens are havens for marine life, from the majestic whale sharks and graceful manta rays to the charismatic napoleon wrasse. Thailand's rich marine biodiversity is complemented by its strong culture of hospitality, welcoming divers of all skill levels to explore its aquatic wonders.

Liveaboard diving is particularly popular, especially around the Similan and Surin Islands, which are renowned for their remote locations and nutrient-rich currents that attract a myriad of marine species. These islands offer some of the best diving spots in the region, with both short and extended liveaboard trips available. For those with limited time, day trips to the Similan Islands provide a glimpse into the vibrant underwater world. Further south, islands like Koh Samui and Koh Tao have become bustling dive hubs, perfect for beginners and backpacking diving enthusiasts seeking a blend of community spirit and exceptional diving opportunities. Here, the competitive dive industry ensures high-quality courses at attractive prices, making Thailand a top choice for both novice and experienced divers alike.
