be true to your soul

This is your time to take good care of yourself.

Potosa Spa is located on the lower level of the historic Hotel Julien Dubuque. Our vision was to create a spa that was the very definition of a boutique hotel spa - true to the history of the area, restorative for mind and body, and offering impeccable service standards.
The spa is named in honor of Potosa, daughter of the chief of the Fox Native American tribe which once inhabited this area. Legend has it she was also the wife of Julien Dubuque. Storytellers have called theirs “a great romance of the Old West.” The logo comes from original wrought iron tiles uncovered in the hotel restoration.
Our menu of spa and salon services is inspired by the Native American Medicine Wheel and includes signature services you will only find here at Potosa.
