According to the current regulations, children aged 4 can go tubing (漂流) in some water parks or designated areas with proper supervision and safety measures. However, it’s best to check with specific facilities for their age restrictions and guidelines before taking your child tubing.

In general, many water parks have certain requirements or recommendations for riders’ ages, heights, and weights, as well as health conditions that may affect their ability to enjoy the activity safely. Some parks might also offer mini-tubing areas designed specifically for younger children with gentle currents and shallow waters.

As a parent, it’s essential to ensure your child is physically ready and emotionally prepared for such activities while still young. So, make sure to check with the water park or facility you’re planning to visit to determine if they allow 4-year-olds on tubing adventures!
