Pinkerton Hot Springs

Roadside mineral mound on the Million Dollar Highway  ·  Not a soaking pool  ·  US-550, north of Durango

Read this before you drive out here

Pinkerton Hot Springs appears on dozens of "free soaking spots near Durango" lists — but it is not a soaking destination. It is a colorful mineral mound with warm water seeping across it: a geological formation you can look at and photograph, not a pool or basin you can get into. Visitors who drive here specifically to soak will be disappointed. This page tells you exactly what Pinkerton is, what to expect, and where to find an actual hot springs soak in the San Juans.

A Mineral Mound on a Mountain Highway — Not a Soak

Pinkerton Hot Springs sits on the east side of US-550 approximately 10 to 15 miles north of Durango in La Plata County — directly visible from the road, with a small dirt pull-off that invites a stop. The formation is genuinely striking: a mound of mineral-encrusted rock stained in rust, orange, and white by decades of warm mineral-rich water seeping through it. Steam rises from the surface in cooler weather. If you've seen photos online, it's easy to understand why people arrive expecting a soak.

But Pinkerton is not a hot springs facility in any meaningful sense. There is no pool. There is no soaking basin. The springs discharge warm water that flows down and across the mineral mound before draining away — the ground is marshy, the surface is slick, and multiple sources explicitly advise against climbing on the formation or attempting to use the water for soaking. Atlas Obscura lists it as a roadside attraction. That's the accurate framing: an interesting geological stop on the way to somewhere else, not a destination in its own right.

This distinction matters because Pinkerton appears alongside legitimate soaking destinations — Strawberry Park, Cottonwood Hot Springs, The Springs Resort — on "free Colorado hot springs" lists without any clarification of what the site actually is. Visitors who drive out specifically to soak sometimes make the trip after a significant detour, only to find a colorful rock formation with no facilities and no practical way to get in the water. This page exists to set that record straight before the drive happens to you.

Quick Facts

Getting to Pinkerton

Pinkerton Hot Springs is on US-550 — the Million Dollar Highway — approximately 10 to 15 miles north of Durango's city center. From downtown Durango, head north on Main Avenue, which becomes US-550. The formation is on the east (right) side of the highway as you head north, clearly visible from the road due to its colorful mineral staining. The pull-off is a small dirt area directly adjacent. You'll know you're in the right area when you see a steam-venting mineral mound on the roadside.

The Pinkerton section of US-550 sits at relatively moderate elevation — well below the dramatic high-country terrain that begins north of here toward Silverton. Winter access is generally reliable, though this stretch of highway sees occasional maintenance operations. Check COtrip.org before any winter visit if there's been recent storm activity or construction notice.

From Ouray or Silverton heading south, the formation appears on the west (right) side of the highway roughly 10 to 15 miles before Durango. The pull-off is small — if you miss it heading south, there's no convenient turnaround on an active mountain highway, so watch for mile markers once you're in the general area.

One firm safety note: US-550 carries significant through-traffic including large trucks, RVs, and motorcycles at speed. When using the pull-off, park fully off the road surface and watch children and pets carefully. Do not step into traffic lanes to photograph the formation from the highway side. The mound is accessible from the pull-off without approaching the road.

What to Expect at the Site

This is a five-to-fifteen-minute stop. The formation is genuinely interesting from a geological standpoint — the mineral color variations, the visible warm seeps, the steam on cold days — but once you've looked and taken a photo, there's not much more to do. Here's the honest walkthrough.

Watch for the Mineral Mound on the East Side

Heading north on US-550 from Durango, watch the east (right) side of the highway for a colorful mineral formation roughly 10–15 miles out. It's clearly visible from distance — the rust, orange, and white mineral staining stands out against the surrounding terrain, and steam is often visible in cooler weather. Slow down well in advance of the pull-off — the dirt area is small and traffic moves quickly on this stretch of highway.

A Mineral Mound, Up Close

The formation is more visually striking at close range than from the highway — the mineral color variations (iron-orange, calcium-white, sulfur-yellow) are vivid, and warm water seeps visibly through fissures in the mound surface. In cool weather, the steam is photogenic. Do not climb on the mound — the surface is slick, the ground around the base is marshy, and the formation is fragile. You can get close enough for excellent photographs without stepping onto the mineral surface itself.

A Photo Stop, Not a Soak

After a few minutes at the formation, most visitors have seen what there is to see. The warm water flowing down the mound drains away quickly — there is no pool collecting at the base, no natural soaking basin, and no practical way to immerse yourself in the water. If you came specifically to soak, this is the moment of disappointment. Take your photos, appreciate the geology for what it is, and get back on the highway. The next destination on US-550 is worth getting to.

The Million Dollar Highway Goes Somewhere Worthwhile

Pinkerton sits in one of the most scenic highway corridors in Colorado. Durango's historic downtown is 10–15 miles south. Continuing north on US-550 takes you through the dramatic climb toward Silverton and eventually Ouray — one of the most spectacular drives in the state. Ouray Hot Springs Pool is about 75 miles north and is a genuine soaking destination with sulfur-free mineral water, five pools, and canyon wall views that earn the drive. Use Pinkerton as a brief curiosity stop on the way to something that delivers the soak you came for.

Pinkerton Hot Springs is worth a five-minute stop if you're already on US-550 and notice the pull-off. The mineral formation is a legitimate geological curiosity — vivid, steam-venting, and unlike anything most visitors see regularly. It is not worth a dedicated drive from anywhere, and it is emphatically not a soaking destination. The internet has done this spot a disservice by listing it alongside actual hot springs facilities without that clarification. We'd rather give you the accurate picture before the drive than explain it after you arrive.

Real Hot Springs Near Durango

If a genuine soak is what brought you to the San Juans, there are two excellent options accessible from Durango — both worth making time for, and both worth planning around rather than treating as a spontaneous side trip.

Ouray Hot Springs Pool is approximately 75 miles north on US-550 — the same highway you're on. It's a full facility operated by the City of Ouray, with five sulfur-free mineral pools ranging from 77°F to 106°F, an adult-only soaking area with views up canyon walls that climb thousands of feet, seasonal water slides, and no reservations required for day use. The drive through Silverton and over Red Mountain Pass is one of the best road trips in Colorado in its own right. Pair a Pinkerton stop with a full day in Ouray and you have an exceptional San Juan itinerary.

The Springs Resort in Pagosa Springs is approximately 60 miles east of Durango on US-160. It's the largest hot springs resort in Colorado — 25 pools, a luxury hotel, spa services, and what's measured as the world's deepest hot spring. The experience skews more resort and less rustic than Ouray, but if you want variety, amenities, and serious soaking infrastructure, Pagosa is the southern Colorado anchor for hot springs travel.

The geology that creates Pinkerton's mineral mound is the same volcanic heat driving hot springs up and down the San Juans. For a soak in what that geology actually produces, Ouray is 75 miles north and worth every mile.
