This site is one of the most family-friendly destinations in the national park. You do not need to hike through the jungle to reach it. Instead, you take a motorized dragon boat directly to the entrance. Once inside, the walking routes are short and flat.

Is the cave safe for toddlers and young children?

Families step directly from the boat onto stable walkways. The paths through the dry sections are well-defined. There are no steep cliffs or dangerous drop-offs on the main route.

Boat operators provide the jackets at the dock before departure. Every passenger must wear one while traveling on the Son River. You can take them off once you step onto the dry paths inside.
