History of Roystone

Throughout its many owners, Roystone Hot Springs has shown its amazing versatility. The fertile land around the mineral springs has been farmed using the warm water for irrigation. The fine vegetables, muskmelons and the orchard were known throughout the Boise Basin.

Later, locals worked to divert the many springs into one cemented catch basin and then built the same swimming pool still used at Roystone today. A photograph from 1909 shows long-skirted women standing next to the pool with laundry barrels and a loaded down clothesline -catching up on work after a swim.

Roystone Hot Springs was then purchased by a man named Roy Stone. He and his nurse turned wife, Eva, purchased it hoping that the healing waters would improve his poor health. Sadly, before he was able to make the move from Portland, he died, leaving it to Eva and her son. She named it in his honor and then built a sanitarium open to all who wished to utilize the mineral springs for their health.

After 2 fires and several more owners, the neglected hot springs were purchased by the Johns Family in the early 80s. Major remodeling and reconstruction of the pool, main house (originally used as a sanitarium and hotel) and surrounding areas have made Roystone what it is today.
