Brief History of Bonneville Hot Springs

Bonneville Hot Springs has been around for thousands of years, healing the many people that travel from afar to bathe in the Bonneville geothermal water. It was found that the mineral-rich water was in use by Native American bathers dating back 10,000 years ago.

The oldest building was the Cascade Springs Hotel that was constructed in 1881 by European pioneer R.J. Snow and served for decades until a fire devastated the structure in the 1930s.

A new campground was constructed in 1932. Called Biba Hot Springs, it flourished and served travelers for a number of decades before declining in 1970s.

The hot springs received a new chance of revival when Pete Cam discovered the magical properties of the hot mineral water. He suffered from rheumatoid arthritis and sought out the hot mineral water to relieve the disease symptoms. He came back for treatment numerous times and, finally, purchased the property in 1989 and later built a resort.
