About this spring
Historic geothermal resort in Idaho Springs featuring a tropical plant-filled indoor mineral pool under a translucent dome (~90-100°F), gender-specific caves with walk-in soaking tubs carved into the mountainside (~108-113°F), private baths, and outdoor jacuzzi tubs — ~30 min west of Denver on I-70.

Indian Hot Springs at 302 Soda Creek Road in Idaho Springs is a historic geothermal resort about 30 minutes west of Denver on I-70. Its signature features are a tropical plant-filled indoor mineral swimming pool under a translucent dome (official average 96–102°F, unadjustable because it's a natural geothermal source) and gender-specific caves — walk-in soaking tubs in passages driven into the mountainside in the early 1900s, averaging 108–113°F with minimal chlorination. The caves are 18+, a designated quiet zone where talking, cameras, and phones are prohibited; swim attire is optional on weekdays and mandatory on weekends. The resort also offers private indoor baths and outdoor hot tubs, lodging, and a spa.
Current pricing: mineral pool about $30 Mon–Thu / $35 Fri–Sun (up to $40 on 'summit' dates), caves $35–45 per person; weekend reservations required or strongly recommended, with timed sessions; towels rent for $5. History runs deep: the Soda Creek springs were neutral sacred ground shared by Ute and Arapaho; prospector George A. Jackson wrote of visiting the springs days before his 1859 gold strike that founded Idaho Springs; Dr. E.M. Cummings began charging for 'health baths' in 1863; Harrison Montague built the stone Ocean Bath House in 1866 and marketed the area as the 'Saratoga of the Rocky Mountains'; the Maxwell family has owned it since 1972. Swimsuits are required in the main pool at all times.
Directions & trailhead access
302 Soda Creek Road, Idaho Springs — take I-70 to Idaho Springs and follow Soda Creek Rd south toward Mt. Evans.
Colorado geothermal context
Colorado's springs rise along fault zones threading the Rocky Mountains — the same tectonics that built the ranges drive deep groundwater circulation. Many sites sit above 7,000 feet, so snowpack closes roads and trailheads well into late spring, and afternoon thunderstorms are routine in summer. Resort valleys like Steamboat, Pagosa, and Ouray anchor the developed end of the spectrum.
What a resort site means here
A resort spring is a commercial operation: developed pools or tubs with controlled temperatures, changing facilities, and usually day-use fees or lodging packages. Expect posted rules (swimsuits, quiet hours, age limits), staff on site, and in many cases required reservations — especially on weekends and holidays.
Best time to visit
Year-Round (Best: May – October)Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across Colorado. Late spring through autumn offers the most comfortable road access.
