Short History

Sharkey Hot Springs has been used as a source of healing by local native people Agaideka (Salmon Eaters) or the Lemhi Shoshone tribe who had lived here for over 16 thousand years.

The first European settlers arrived in 1867 and this site was once part of an old trading route used by early trappers. The hot springs was names after Frank Sharkey, a rancher who settled at the springs in the 1870s.

From the 1920s to the 1960s, the hot springs had been a popular bathing site with a swimming pool, changing rooms, and cabins. However, during some time, the site fell into disrepair and BLM got rid of all aging structures for safety reasons in 1973.

In 2002, Sharkey Hot Springs was rebuilt and open to the public.

Today, it serves as a popular destination for locals looking for a peaceful respite amidst nature's beauty just outside town limits while also drawing travelers who come here to seek out the healing properties of geothermal mineral water.
