Located next to the Río Chinchiná just outside Manizales, this thermal-bath complex has three pools made of rocks set among a pretty garden that attracts hummingbirds and butterflies. There's an elevated, open-air restaurant and a small spa offering a wide range of massages. The baths are quiet during the week, but on the weekends it can feel a little overcrowded.
There's also a good-value hotel on-site with four spacious, modern rooms (single/double from COP$170,000/190,000) sporting full-length windows overlooking a stream. On Sundays there's often cut-price admission.
