Tarutao Marine National Park is the largest marine preserve in both Thailand and Southeast Asia. Founded as Thailand's second marine national park in 1972, it comprises 51 islands in three distinct groups, located in the balmy waters of Thailand's Andaman Sea.
Thailand has more than its fair share of picture-perfect islands and beaches but what makes Tarutao so special is that, with the exception of the tiny island of Ko Lipe, no private resorts or infrastructure developments are permitted. This regulation is very strictly enforced.
