The short answer
Ang Thong Marine National Park: what visitors should know first
Good for confident walkers and swimmers in calm months, but it is a long day with boat time and uneven ground. Choose a reputable operator and avoid it in the rough-sea months from July to October.

Why it matters
Why Ang Thong Marine National Park is worth your time
Ang Thong has been a national marine park since 12 November 1980. The scenery of limestone islands rising from clear water gives a sense of the Gulf's natural coastline, and the park is one of the few places in the area where development is restricted.
For Indian visitors, a day here is a break from the temple-and-beach routine. For older relatives, the length of the day is the main consideration.

How to experience it
Book a day trip from your hotel or a licensed operator in Bophut, Chaweng or Nathon. The park covers 42 islands and about 102 square kilometres, with only part of that being land. Typical tours stop for swimming, snorkelling, kayaking or a short hike, but programmes vary, so ask exactly what your tour includes.
Bring sun protection, a hat, a light waterproof layer and any motion-sickness medicine you need. Seas can be rough in the wetter months, and July to October sees heavier rain and sometimes rough seas.
If you or your parents tire easily, choose a smaller group or a shorter option, and decide in advance whether to skip the hike.
