Glacier Hiking & Geothermal Cave Pools Tour
Book on Viator →Operated by Adventure Colorado Tours · Bookable on Viator
Snow, caves, and views in one day. This small-group adventure pairs a short glacier hike with provided snow gear and ends at Indian Hot Springs for warm mineral-water soaking inside rock-hewn caves, with guides like Tyler, Dan, Trey, and Ariel often praised for pacing and friendly coaching. I also like the built-in value: hot springs admission is included, plus parking fees and transfers, so you’re not spending your day hunting details and receipts.
One real consideration: the hike starts high. A past guest flagged the climb beginning around 10,200 ft, which can hit harder if you’re sensitive to altitude, even though the walk is relatively short.

Key highlights you’ll care about

- Max 4 travelers: easier conversation, more personal pace control
- St. Mary’s Glacier is short (about 1.5 miles round-trip): good for active first-timers who still want real views
- Hot springs caves in solid rock (1903–1911): walk-in tubs in the 104–112°F range
- Caves are gender specific; kids 16 and under aren’t allowed in the caves: plan ahead if you’re traveling as a family
- Gear is included: crampons for grip, sleds, and ski goggles if needed
- Idaho Springs stop + Beau Jo’s pizza: a classic Colorado meal break before you head back
A Small-Group Day Trip From Denver: Easy Pickup, No Guesswork

You start downtown, right at Whole Foods Market on Wewatta Street at 8:00 am, and you end back where you met. It runs about 8 hours, which is a sweet spot: enough time to get outside, earn a soak, and still feel like you did something real without turning the day into an all-day logistics project.
The group size is tiny (up to 4 travelers). In practice, that matters. You’re not stuck waiting for a crowded bus line or getting rushed through the hike because someone else is slow. It also makes it easier for the guide to help with pacing, questions, and adjusting for comfort level—something guides such as Tyler, Dan, Trey, and Ariel are repeatedly praised for.
Transfers are included too. So if you’re staying in Denver without a car, you’re not stuck doing a DIY expedition with parking stress and navigation anxiety. You’ll also get parking fees covered, plus water and snacks during the day, which helps a lot once you’re climbing at altitude.
Finally, this is an outdoor tour that’s dependent on weather. The good news is that if conditions are poor, you should be offered a different date or a full refund. The not-so-fun news is that you’ll want to treat it like a weather-sensitive plan, not a “guaranteed no-matter-what” outing.

St. Mary’s Glacier Hike: Short Walk, Big Colorado Payoff

The glacier part is designed to be approachable. St. Mary’s Glacier is described as one of the easier trails in Colorado, with a total of about 1.5 miles round-trip. That’s not a long hike—so you’re not grinding for hours. You’re moving at a steady pace, stopping when it makes sense, and spending most of your energy on enjoying the views and the snow texture.
The setting is what makes it feel special. You hike up through Colorado forest, and the climb finishes with panoramic viewpoints. Even if you’re not a serious mountaineer, you’ll still get that wow feeling of being above the trees and close to real glacial terrain.
Now, the part to take seriously is altitude. Even with a shorter distance, you can feel it when you start around 10,200 ft. If that’s a concern for you, plan to go slower than you think you need to, sip water regularly, and let your body catch up. Several guides are praised for pacing and for coaching people through the altitude challenge, so you’re not left to figure it out alone.
I’d also plan on traction. Crampons (grip for snow) are included, and that’s a big deal for confidence on slick sections. One guest specifically called out the value of crampons plus ski goggles in winter conditions. If you’re the type who hates slipping on ice, this is the difference between white-knuckling the climb and enjoying it.
One more smart tip: bring layers you can adjust. The glacier day can feel chilly at first, then warmer once you’re walking. Even though the tour provides cold-weather gear like goggles and crampons, your clothing comfort is still on you.
Traction, Sleds, and Ski Goggles: Gear That Turns Risk Into Fun

This tour includes several cold-weather items, which is exactly what you want for a glacier day trip.
- Crampons are included for grip on snow and ice. This is the safety core.
- Sleds are provided if needed. That hints the day may include playful snow segments depending on conditions.
- Ski goggles are provided if needed, which matters on bright days when snow glare can be intense.
I love this setup because it protects your vacation budget. Instead of renting gear last-minute or buying items you’ll only use once, you show up and get what you need. It also means you can travel lighter—always a win when you’re hopping between cities.
That said, you still need to dress like you expect snow and cold air. Guides can’t control the weather or your personal comfort. If your skin runs sensitive to chill, consider bringing a warmer base layer and gloves you’re comfortable moving in.
One small, practical bonus from the day’s structure: many guests describe a calm, organized flow with a quick water/bathroom break before the hike. You might get those moments that keep you from rushing. It’s not flashy, but it makes the day feel smooth instead of chaotic.
Indian Hot Springs Caves: Walk-In Tubs Inside Rock-Heads (104–112°F)

After the hike, the day shifts gears fast—in the best way. Indian Hot Springs uses caves carved into the side of a mountain. The facility was created between 1903 and 1911, and you soak in naturally hot mineral water that runs from 104° to 112°F.
This isn’t a quick dip. It’s a long, restorative kind of soaking. Think of it like recovery time that also feels like part of the attraction. The caves are set up with large, sunken walk-in hot tubs, so once you’re in, you’re not fighting awkward angles or standing around trying to find the right spot to relax.
There are a few rules to know so you don’t feel surprised:
- The caves are gender specific.
- Bathing suits are optional.
- Children 16 and under are not allowed in the caves.
If you’re traveling as a couple or a group of mixed preferences, this is where planning matters. You’ll want to make sure everyone is comfortable with the gender-specific setup, and families should double-check suitability based on the 16+ cave rule.
Also, this is hot enough that your body will notice right away. Hydrate before and after the soak. Don’t treat it like a hot tub you can rush through. The best experience comes when you slow down, sit back, and let the warmth do the work—especially if the altitude had you feeling it earlier.
A couple of guests also recommend practical items like flip-flops for moving around comfortably. Even if the tour doesn’t list footwear, that’s the kind of small add-on that can make your cave time easier.
Idaho Springs Break and Beau Jo’s Pizza: The Reward Stop

After soaking, you’ll head to Idaho Springs, a mountain town that works well as a decompression break. You get time to eat and walk around a bit, rather than turning the second half of the day into another hard workout.
Pizza at Beau Jo’s is part of the plan. This is one of those Colorado staples people get excited about for a reason: it’s filling, comforting, and perfect after you’ve been hiking and warming up in caves. The tour doesn’t list lunch as included, so you’ll likely pay for your meal there, but the stop is built into the schedule so you’re not hunting for something quickly after the hot springs.
One handy suggestion from guests: if you think you might take leftovers back, consider bringing a container (a guest mentioned bringing Tupperware). It’s an easy way to stretch that comfort food into a second meal later.
This town stop is also useful because it lets you reset mentally. The day starts early, involves snow traction and altitude, and then shifts into heat. A lighter town hang gives your body time to settle and helps the day feel complete instead of abrupt.

Who This Tour Fits (and the Small Things to Prepare)

This outing is aimed at active travelers who like the outdoors. The hike is relatively short, but it still expects you to be comfortable being outside on snow/ice and handling altitude. In other words: it’s not extreme marathon fitness, but it’s not a flat, casual stroll either.
It’s especially a good fit if you:
- Want a short glacier experience without committing to a multi-day expedition
- Like pairing outdoor effort with a real recovery soak
- Prefer small groups and guide attention
- Appreciate clear structure and included gear
It’s less ideal if you:
- Know you get hit hard by altitude, especially if you’re expecting a low-elevation hike
- Need to travel with children who would want to be in the cave hot tubs (the cave rule is 16+ only)
- Are uncomfortable with gender-specific cave areas
If you’re a solo traveler, this kind of small group can also feel social without being overwhelming. Several guests describe making connections in the group, and the guide-led tone seems to keep things friendly and organized.
One other thing that can shape the vibe: guides sometimes add thoughtful touches during the climb. A guest described guided meditation to help with mindset and getting up in snowy conditions. That might not be your exact experience, but it signals the guides tend to bring more than just route information—they coach comfort and confidence.
Some guides also hand out keepsakes. One guest specifically mentioned receiving a Polaroid at the end. If that kind of small souvenir matters to you, it’s worth looking forward to, even if it’s not guaranteed every time.
Should You Book This Glacier + Thermal Caves Tour?

I’d book this if you want a day that mixes real Colorado outdoors with a genuinely relaxing endpoint—without renting gear, worrying about transportation, or losing hours to meal-finding. The best value pieces are the included hot springs admission, included gear (crampons, sleds, ski goggles if needed), water/snacks, and covered parking and transfers. That combination turns it into a straightforward, “show up and enjoy” kind of outing.
My “pause and think” advice is altitude. Even with a short hiking distance, the climb starts high, and one guest flagged the 10,200 ft beginning as a surprise. If you’re altitude-sensitive, don’t ignore it. Go slow, hydrate, and be honest with yourself about what your body can handle.
Also, if you’re traveling with kids, read the hot springs cave rules carefully. The caves are 16+ only, and they’re gender specific. Those facts shape whether this is a perfect family plan or a hard mismatch.
If those considerations work for you, this tour hits a great sweet spot: glacier views, winter gear confidence, then mineral-water warmth inside rock caves—plus a classic pizza stop to end the day on a satisfying note.
