About Raspberry Hot Springs
Raspberry Hot Springs, Colorado is a private, reservation-only geothermal resort on a 30-acre ranch at 9,000 feet elevation in the mountains above Idaho Springs. It features a single stone-lined soaking pool fed by a natural hot spring, accompanied by a cedar sauna and private restrooms, set against sweeping views of peaks across Clear Creek County. The nearest point for supplies or lodging is Idaho Springs, roughly 12 minutes down the mountain, making it a convenient base for visitors planning a soak.
The ranch is privately owned and operated, and every booking grants a group exclusive use of the pool for one to two hours, with no other guests sharing the water. The hot spring water rises from geothermal activity beneath the Colorado Rockies, the same broad system of volcanic and crustal heating that produces natural hot springs in colorado throughout the state. The setting is completely off-grid, with no outside lighting at night and limited cell coverage on the access road.
Reservations typically book out weeks in advance, particularly on weekends. The spring operates year-round, and winter visits are among the most popular, when the contrast between cold mountain air and warm water is most pronounced.
Location & Access
Getting to Raspberry Hot Springs
Raspberry Hot Springs is reached via Chinook Road, a steep unpaved dirt road off Fall River Road, approximately 5 miles from I-70 Exit 238 near Idaho Springs. AWD or 4WD with a minimum of 7.5 inches of ground clearance is an absolute requirement on the access road, which rises sharply on a rocky surface with drainage ditches that will ground out standard vehicles. In winter months, 8 inches of clearance is required and snow tires or chains are strongly advised.
From Denver, the drive takes approximately 40 to 45 minutes heading west on I-70. From Idaho Springs town center, the drive to the ranch is roughly 12 minutes. The final stretch of Chinook Road is narrow, single-lane in places, and shares access with a small number of private residents on the mountain. An alternative access route via Dakota Ridge Road exists but is only advisable for experienced off-road drivers in dry conditions; the primary Chinook Road route is strongly recommended for all visitors who are not confident in extreme 4x4 terrain.
Arrivals must have a confirmed reservation and are sent detailed check-in instructions in advance. No walk-in visitors are accepted under any circumstances. The property address is 899 Chinook Rd, Idaho Springs, CO 80452. For anyone looking for accessible hot springs near Idaho Springs using a standard vehicle, this location is not suitable due to the mandatory vehicle requirements.
Suitability & Accessibility
Who Is Raspberry Hot Springs For?
Raspberry Hot Springs suits adults aged 21 and over who are looking for a private, secluded soaking experience in a mountain setting, as the minimum age requirement is strictly enforced and no exceptions are made for any booking. The experience is well matched to couples, small groups of friends, or solo travelers who want exclusive access to a natural spring without crowds. It is not suitable for families with children, as the 21-and-over policy applies regardless of group composition.
Once at the spring, the terrain around the pool is relatively level and the walk from the parking area is short, but the overall property is a working mountain ranch at altitude and is not designed as an accessible facility. Wheelchair access is not documented by the operator, and the unpaved road, uneven ground, and outdoor mountain conditions make it unsuitable for guests with significant mobility limitations. Those seeking accessible hot springs in Colorado should look for purpose-built facilities with paved access and confirmed accessibility features.
The 9,000-foot elevation means that visitors arriving from lower altitudes may notice the effects of altitude, including mild shortness of breath during exertion. The operator publishes age and health requirements on its website and asks guests with cardiovascular conditions or other health concerns to review these before booking. Soaks are booked in one-hour and two-hour increments, with three-hour blocks available on request, allowing guests to choose a duration that suits their schedule and physical comfort.
Safety & Etiquette
Raspberry Hot Springs Safety Tips
Raspberry Hot Springs is generally safe for soaking, but the access road and mountain location introduce real hazards that visitors must take seriously before making the trip. The road to the ranch is steep, rocky, and exposed to weather, and guests who attempt the route in an unsuitable vehicle may become stranded on a narrow mountain road with no refund available for failed access attempts. Verify that your vehicle meets the AWD or 4WD and minimum ground clearance requirements before booking.
There is no lifeguard on duty at the pool. The hot spring operates as a self-managed experience, and guests are responsible for their own safety in and around the water. The 21-and-over policy reduces hazards around an unguarded geothermal pool in a remote location. Water temperature in the pool can be warm to hot, and guests who are sensitive to heat, pregnant, or have cardiovascular conditions should consult a medical professional before soaking.
The ranch sits at 9,000 feet in a mountain environment with rapidly changing weather. Afternoon thunderstorms are common in summer, and lightning exposure is a real risk at elevation. If a storm develops, exit the water and seek shelter in your vehicle or the onsite sauna. Cell coverage on the access road and at the property is limited, so download offline maps and inform someone of your plans before heading up.
Pack out all waste, avoid glass containers near the pool, and respect posted notices from the operators. Arriving on time and departing promptly ensures the experience remains pleasant for all groups using the site.
