Southern Thailand is probably the most diverse region in the kingdom. It is a place of dense forests, imposing mountains and deep caves. It is also a place of rivers, waterfalls and lakes. Most of all it is home to some of the world's most glorious islands and beaches. Whether they are islands like Phuket and Koh Samui that are geared for the well-healed tourist, or destinations like Koh Surin that attract the more adventurous, or even Koh Phangan where beach party animals dance to the small hours of the morning, the south of Thailand has something for everyone.
