Best Hot Springs Near Aspen

One of the best ways to balance out ski days, hiking, and exploring Aspen is with a hot springs soak — and the good news is, you’ve got a fair number of options.

While Aspen itself doesn’t have hot springs, there are several excellent hot springs near Aspen just a short drive away, making it easy to add a soak to your itinerary without much extra planning.

Whether you’re after a spa-style experience or a low-key riverside soak, here’s where to go and how to plan it.

Best Hot Springs Near Aspen

Iron Mountain Hot Springs (Glenwood Springs)

Distance From Aspen: About 1 hour drive

Vibe: Scenic spa-style soaking | Cost: $$$ | Reservations: Timed-entry required (book here)

Iron Mountain is one of the most scenic and thoughtfully designed hot springs in the area. It sits right along the Colorado River and features multiple tiered pools at different temperatures, so you can move around and find which is best for you. The vibe is relaxed but polished — think spa energy without feeling overly fancy. There’s also an adults-only area with a bar and additional soaking pools if you want a quieter experience (specific ticket required).

You’ll need to book a timed entry ticket in advance, especially on weekends and during ski season. Lockers and two towels are included with admission, which is a nice perk. Try to arrive early if you want prime river-facing spots — sunset is especially popular (and absolutely worth it if you can snag a reservation). Check pricing and availability at Iron Mountain Hot Springs.

Avalanche Ranch (Redstone)

Distance From Aspen: About 1 hour drive

Vibe: Rustic and peaceful | Cost: $$ | Reservations: Required (book here)

Avalanche Ranch is one of the best low-key hot springs near Aspen if you’re craving something quieter and more nature-focused. It’s tucked into a forested valley outside of Redstone, a small hidden gem town in the Crystal River Valley. The setting feels intimate and secluded, with three cascading soaking pools at different temperatures surrounded by trees and mountains.

Reservations are required and time slots for day visitors are limited, so you’ll want to book ahead — especially on weekends. Bring your own towel and flip flops, and don’t expect reliable cell service once you arrive. Check pricing and availability at Avalanche Ranch.

Glenwood Hot Springs Pool (Glenwood Springs)

Vibe: Classic resort soak | Cost: $$ | Reservations: Book online or walk-in (book here)

This is the big, iconic hot springs pool you’ve definitely seen photos of — and yes, it’s massive. It’s officially the world’s largest hot springs pool and is fed by the Yampah Spring. The setup is more of a traditional resort-style experience with one enormous main pool, a therapy pool, and full locker room facilities.

It’s family-friendly, social, and noticeably livelier than smaller soaking spots. The resort dates back to 1888, so while it’s well-maintained and modernized, it’s helpful to go in with realistic expectations — historic properties come with a little character. 

You can reserve online or walk in, which makes this an easy spontaneous stop. Lockers are free, but towels cost extra (or bring your own). For a calmer experience, aim for early mornings or late evenings.

Penny Hot Springs (Carbondale Area)

Distance From Aspen: About 40 minutes drive

Vibe: Natural riverside soak | Cost: Free | Reservations: None

Penny Hot Springs is one of the most popular natural hot springs near Aspen. It sits right along the Crystal River with gorgeous mountain views and small, rock-formed soaking pools. 

Since this is public land, there are zero facilities — no bathrooms, no changing rooms, and no trash service — which means everything you bring in must leave with you. Pack out all trash, food, and belongings, and leave the area exactly as you found it.

The pools are small and typically only fit around 10 people at a time, with no crowd control, so visiting during off-peak hours is key. Conditions also change depending on river flow, and the pools are often flooded during spring and early summer snowmelt. 

Penny is located right off the road with roadside parking available. Winter soaks are especially magical, but getting in and out can be icy, so water shoes help. Clothing is required.

Note: South Canyon Hot Springs is another natural hot spring in the area, but it’s reviews aren’t great, I’d skip this one and head to Penny instead.

Yampah Spa & Vapor Caves (Glenwood Springs)

Distance From Aspen: About 1 hour drive

Vibe: Historic steam cave spa | Cost: $$ | Reservations: Strongly recommended (book here)

Yampah is a totally different experience compared to the other hot springs on this list. Instead of open-air soaking pools, this is a historic underground vapor cave system where natural geothermal steam fills stone chambers beneath the spa. You descend into warm, dimly lit rock rooms lined with stone benches, where mineral-rich steam rises from hot water channels in the cave floor. It’s more like a sauna–hot spring hybrid than a traditional soak.

The facility dates back to the late 1800s, so while it’s been updated and maintained, it still has that old-school spa charm (and quirks that come with historic buildings). You can also book private mineral baths upstairs for a more classic soaking experience. 

Reservations are highly recommended since both vapor cave sessions and private tubs book out quickly. Check availability and pricing at Yampah Spa & Vapor Caves.

Conundrum Hot Springs (Backcountry)

Distance From Aspen: About 9 miles one-way hike (no road access)

Vibe: Backcountry wilderness soak | Cost: $ | Reservations: Permit required (book here)

Conundrum Hot Springs is legendary — and also very much not casual. This is a true backcountry hot spring accessed by a long, steep hike (just over 17 miles round-trip), usually done as an overnight backpacking trip. The reward is unreal: natural hot pools surrounded by alpine peaks, open sky, and complete wilderness.

Permits are required to camp overnight, and there are strict regulations in place to protect the area, including designated campsites and group size limits. This experience is best suited for advanced hikers who are properly prepared with gear, navigation skills, and weather awareness. If you’re up for the challenge (and able to snag a permit), this is easily one of the most unforgettable hot springs experiences in Colorado.

Additional Hot Springs Options In Summer

When Independence Pass is open (typically late May through October, depending on snow), you unlock even more hot springs east of Aspen. Below are some of the most popular options.

Buena Vista Hot Springs

Distance From Aspen: About 2.5 hours via Independence Pass (seasonal route, summer through early fall)

Cottonwood Hot Springs – Cottonwood Hot Springs is a classic Colorado soaking spot with a rustic, no-frills vibe. The pools sit at the base of the Collegiate Peaks and feel peaceful and scenic without being overly resort-like. It’s affordable, easy to access, and one of the best options if you want a relaxed, traditional hot springs experience. Find pricing and information at Cottonwood Hot Springs.

Mount Princeton Hot Springs – Mount Princeton is the most resort-style option in the area, with multiple developed pools, riverfront soaking areas, and on-site lodging. You can choose between higher-temperature pools near the main facility or quieter creekside pools along Chalk Creek (creekside pools fill quickly!). It’s a great pick if you want full amenities, locker rooms, and an easy, comfortable soaking experience. Pricing and additional information can be found at Mount Princeton Hot Springs.

Charlotte Hot Springs – Finally, Charlotte Hot Springs is a small, developed soaking area connected to Merrifield Homestead Cabins, with just three pools open to the public and access to their small botanic garden included with admission.
