The mud baths at Thap Ba natural hot springs are a healthy and fun way to spend a few hours. The best time of day to go is between 12:00 and 15:00 when they are less crowded. You will be offered single or shared mud baths and obviously the single ones are more expensive yet the communal tubs are more fun. Shower off in mineral-rich water afterwards or let the mud dry on you first for additional benefits before showering.
