Captain Henry E. Boyes found the hot spring beneath this resort in 1895, and the rebuilt hotel opened in 1927. Its spa, billed as 40,000 square feet, has geothermal mineral pools, a eucalyptus steam room and a halotherapy sauna, with day access sold to non-guests. A separate family-friendly resort pool also uses naturally heated water.
