The original hot thermal mud centre is good value and makes a fine day out. Dong-watchers should opt for the communal mudbath (160,000d; 20 minutes maximum time); there are also mineral-water swimming pools. Lots of other packages are available. It's 7km northwest of Nha Trang (130,000d in a taxi).

To get here under your own steam, follow the signpost on the second road to the left past the Po Nagar Cham Towers and continue along the winding road for 2.5km.
