Idaho Springs presently prospers from the hot springs at Indian Hot Springs Resort. Around the springs, known to the Ute natives as the "healing waters of the Great Spirit," are geothermal caves that were used by tribes as a neutral meeting site. The hot springs, a translucent dome–covered mineral–water swimming pool, mud baths, and geothermal caves are the primary draws for the resort. You don't need to be an overnight guest to soak in the mineral-rich waters; day rates start at $19 for the geothermal cave baths (depending on type of bath and day of week), outdoor Jacuzzi baths $21.50, and $14 for the pool. The plain but comfortable spa offers massages and facials.
