Indian Hot Springs in Idaho Springs, Colorado: The Complete Visitor Guide

Indian Hot Springs is a historic mineral hot springs resort in Idaho Springs, Colorado, about 45 minutes west of Denver on I-70. It has been a commercial bathhouse since 1863, when it opened as the Saratoga of the Rockies, and Ute and Arapaho people used the same springs long before that. The resort runs four different soaking experiences on one property: a covered mineral pool, a set of small underground geothermal caves, private indoor baths you rent by the hour, and seasonal outdoor jacuzzi tubs.

This guide covers how to choose between the four pools, what the cave mud baths are really like, how pricing works, when to go to avoid the post-ski crowd, and how to stack a soak with St. Mary's Glacier or a drive up Mount Blue Sky.

Where Indian Hot Springs is and how to get there

Indian Hot Springs is in downtown Idaho Springs, a small mountain town tucked into Clear Creek Canyon along I-70. The property sits on Soda Creek Road just a few blocks off the interstate, walking distance from the main Idaho Springs strip.

From Denver (35 to 50 minutes): I-70 west to Exit 240 (Idaho Springs). Turn left at the bottom of the ramp onto Colorado Boulevard, right on 13th Avenue, then a quick left onto Soda Creek Road. The resort is on the right after a short block.

From Golden (30 minutes): US-6 west to I-70, then west to Exit 240.

From the I-70 ski areas (Loveland, A-Basin, Keystone, Breckenridge, Vail): I-70 east to Exit 240. Coming down from the ski areas in late afternoon is the busiest window of the week at the property. Plan accordingly.

Parking on-site is free, but the lot fills on winter weekends around 3 PM as skiers come off the mountain. If it's full, street parking around Idaho Springs is plentiful.

The four water experiences

Indian Hot Springs is not a single pool. It is four different soaking environments on one property, and the day pass covers two of them while the others cost extra.

The main mineral pool

The main pool is a large covered swimming pool fed by the natural springs and kept between 95 and 100°F. It sits under a tall geodesic dome that lets light in but holds the heat, so you can soak comfortably even when it's snowing outside. The water has a slight mineral smell and a soft, slick feel. Mixed-gender, swimsuit required. Capacity is large enough that the pool rarely feels packed except on weekend afternoons.

The geothermal caves

The caves are the most distinctive experience on the property and the reason most people drive up from Denver instead of going to a regular spa. Underground tunnels carved into the bedrock house small, single-sex soaking pools fed directly by the hot springs at the source. Men's and women's caves are separate.

Water temperatures in the caves run hotter than the main pool, often 104 to 108°F. The rock walls drip with mineral deposits, and some visitors collect mud from the walls and apply it as a face or body mask, then rinse it off in the pools. The caves are clothing-optional within each single-sex section. Plan to spend an hour here. It's the signature experience on the property.

Private indoor baths

A row of private indoor baths rents by the hour. Each is a small tiled room with a single tub fed directly by the springs, fitting two adults comfortably. Clothing is optional inside because the room locks. Private baths are popular with couples and anyone who wants to soak without sharing water. Walk-in availability dries up by mid-morning on Saturdays. Book ahead.

Outdoor jacuzzi tubs

A small cluster of outdoor jacuzzi tubs sits on the back deck, open seasonally and dependent on weather. The tubs are smaller than the main pool, hotter (around 102 to 104°F), and the closest thing to a true outdoor soak the resort has. Call ahead in winter for availability.

How pricing works

Pricing is set up by experience, not by time. Rough structure as of 2026:

• Day pass (main pool plus caves): $25 to $30 per adult depending on the day. Unlimited time in the main pool and caves.
• Private bath rental: $25 to $35 per hour for the room, subject to bath capacity.
• Children and seniors: Discounted, typically half off for kids under 12.
• Towel rental: A few dollars at the front desk.
• Lodging packages: Overnight rates include day pass access for the duration of the stay.

Cash and major credit cards accepted. Prices fluctuate seasonally and on holidays. No advance reservation system for the day pass: you walk in, pay, and change in the locker rooms.

The 1860s history of the property

The mineral springs were used by Ute and Arapaho people for centuries before Colorado was a territory, primarily as a winter gathering site and a healing place. In 1863, prospector Dr. E. M. Cummings opened a commercial bathhouse on the property and named it the Saratoga of the Rockies, modeled after the famous mineral spas of upstate New York. Idaho Springs was a booming mining town then, and the bathhouse drew both miners off the gold camps and wealthier visitors from Denver looking for a mountain retreat.

The current main building dates to the early 1900s, when the property was rebuilt in the wood-and-stone mountain-lodge style that still defines it. The geodesic dome over the main pool was added much later. The resort is currently operated by Indian Hot Springs LLC.

On a visit, the property feels much more like a historic lodge than a modern spa. The locker rooms are simple, the lobby has old photographs on the walls, and the hallways feel like an old hotel. That texture is part of why people love it.

Staying overnight on the property

The resort has on-site lodging in a historic main building that dates to the early 1900s. The rooms are rustic. This is the most important sentence in the section. If you are looking for a luxury hot springs hotel like Glenwood Hot Springs Lodge, you will not find it here.

What you get is a small mountain-lodge room with a bed, a private or shared bathroom depending on the room type, and unlimited access to the pools and caves during your stay. Some rooms are cabins on the property. Rates run from about $130 to $250 a night depending on the room and the season. Winter weekends book out weeks in advance.

Idaho Springs the town: food and beer after a soak

Idaho Springs is a working mountain town. The strip along Miner Street has half a dozen good food and drink spots within a few blocks of the hot springs.

Tommyknocker Brewery. The flagship Idaho Springs brewery, opened in 1994. Solid pub food (burgers, fish and chips, green chili) and the maple nut brown ale. Five-minute walk from the hot springs.

Beau Jo's Pizza. A Colorado institution. Mountain Pies are deep-dish pizzas with a thick honey-brushed crust. Beau Jo's started here in 1973 and now has locations across the state. Worth the visit even if you've eaten at the Denver one.

Westbound & Down Brewing. Newer craft brewery a few blocks east, known for IPAs and lagers. Less of a tourist scene than Tommyknocker, more of a locals-and-skiers room.

If you're driving back to Denver after a soak, plan to stop in town for at least one meal.
