Welcome to our round-up of all seven publicly accessible natural hot springs in Colorado! These are all free to visit, so it's extremely important to be respectful and leave no trace when you visit these special places. In addition to lots of beautiful photos of each hot spring, we've included the dates photos were taken so you can get a real feel for what each hot spring is like during different times of year. We've also created a map showing where each hot spring is located in the state. You could even plan a Colorado road trip to visit more than one hot spring! Keep in mind that because most of these hot springs are located on the edges of rivers, they can be washed out and inaccessible during the snow melt in spring.
- Radium Hot Springs - an easy 1 mile hike makes these springs fairly accessible. They're located on the Colorado River, north of the Vail Valley area.
- South Canyon Hot Springs - an even shorter 0.2 mile hike, these springs are located near Glenwood Springs and are quite popular due to their accessibility.
- Penny Hot Springs - another very short hike from the parking area, these springs are located just south of Carbondale.
- Conundrum Hot Springs - the highest natural hot springs in North America at 11,200 ft, you'll need to hike 18 miles round trip hike to access them! Trailhead begins near Aspen.
- Rico Hot Springs - an easy 0.1 mile hike from the parking area near Rico (sort of between Telluride & Durango) but unfortunately this hot spring is currently marked as CLOSED on All Trails; it looks to be on private land.
- Piedra River Hot Springs - a 3 mile round trip hike will lead you to this series of ever-changing pools along the Piedra River, near Pagosa Springs in southwest Colorado.
- Rainbow Hot Springs - another big hike (10 miles round trip) is required to enjoy these springs located near Pagosa Springs in southwest Colorado. One perk: there's a great waterfall you'll spot along the way!
Radium Hot Springs
Radium Hot Springs are located on the Colorado River between Bond & Kremmling (just north of the Vail Valley region). The trail is a short and moderately difficult 1.5 mile loop trail up and across a mesa, then steeply down to a beautiful scene of the famous river and its surrounding cliffs.
The springs themselves are all natural and primitive; the spring mixes with river water for an average water temperature in the 80s. In the spring, during high water due to snow melt, the pool is frequently washed out.

South Canyon Hot Spring
South Canyon Hot Springs is a 0.2 mile short and accessible out and back trail located near Glenwood Springs. They're located on the South Canyon River, which is an offshoot to the south of the Colorado River, just west of Glenwood Springs. These natural hot springs are very popular due to their accessibility so please take care to clean up after yourself and help maintain their beauty for all to enjoy.

Penny Hot Springs
Easy to access off highway 133, south of Carbondale, these hot springs are located along the Crystal River (a southern offshoot of the Roaring Fork) and are very easy to access. The parking pull off can be found between mile markers 56 and 55. There are no signs for the springs, but they can be seen from below the pull off. You'll be able to see the pool because it is sectioned off with large rocks to keep the cold water from coming in; temperatures vary, and can be adjusted by adjusting the rock wall. As with most of these natural river hot springs, they can get flooded out during the spring when snow is melting.

Conundrum Hot Springs
Of all the hot springs listed here, this one the most challenging to reach...Conundrum Hot Springs is the highest hot spring in North America at 11,200 ft!
Get ready for a 16 mile hike (round trip) to get here. Trail reports estimate 5-8 hours to hike in, then another 3-4 hours to hike back out. Starting elevation is high at 8,000 feet, and ends at 11,000 ft so make sure you're up for the challenge!
The trail is packed with wildflowers, river scenery, and wildlife so the payoff is huge. Permits are required for camping in the area, so check out recreation.gov to get those taken care of.

Here's a sneak peek of the hike in to Conundrum ... not bad, either!

And here's a video tour of the Conundrum hike & hot springs themselves! This gives you a really good feel for the experience. Skip to 2:45 for the actual hot springs.
Rico Hot Springs
A very short easy hike (0.1 miles) leads to these natural hot springs off the Dolores River, just outside of Rico, Colorado. If you haven't heard of Rico before, it's a little town in southwestern Colorado - about an hour northeast of Cortez in the San Juan Mountains. Unfortunately, these hot springs are currently marked as CLOSED on all trails; it appears they may be located (or access to them is located) on private land.

Piedra River Hot Springs
At three miles round-trip, near Pagosa Springs, Piedra involves a fairly short but steep (there’s a big descent near the beginning) hike along the Sheep Creek Trail. At the edge of the Piedra River, you’ll find around a dozen pools of varying depths and temperature, all of which change constantly. These are usually flooded out in the spring, just like most of these natural hot springs. Local wildlife loves this spot - there have even been reports of river otters living nearby! Another interesting thing to check out while in the area is Chimney Rock, a lunar observatory sacred to the Ancestral Puebloans.

Rainbow Hot Springs
Rainbow Hot Springs is another one that requires a fairly big hike in, but the payoff is worth it! Located in the San Juan National Forest near Pagosa Springs, you'll need to conquer a 10 mile out and back trail to reach these hot springs. One perk: there's a great waterfall you'll spot along the way.
There was an avalanche in the area in 2019 with some resulting trail washouts, but hikers report that the trail is still passable and the hot springs are active.
