Is it worth it to go to the Similan Islands with small children

If you have small children, you might want to think twice before taking them to the Similan Islands. The trip to Similan is too tiring and challenging for small children, for several reasons:

  • The boat ride is long and bumpy. It takes about an hour and a half to reach the islands from the pier, and the same time to return. The boat can be crowded and noisy, and the waves can be rough and splashy. Your children might get bored, restless, or sick during the ride.
  • The snorkeling is not suitable for beginners. The water is deep and the current is strong in some areas. Your children might not be able to see much or enjoy the snorkeling if they are/

Tours to Similan islands are too tiring for small children. There are more child-friendly tours to Koh Racha.
