Iron Mountain Hot Springs 2026: Prices and Hours

Iron Mountain Hot Springs is a hot springs resort in Glenwood Springs, Colorado, with 35 pools, and it sells two passes: General Access for $43 to $75 and All Access (21 and over) for $75 to $150. It is open every day from 9 a.m. to 10 p.m. The official pricing page gives price ranges only, not a price for each day. On 8 November 2026 we compared the trip from Denver: the train takes 6 h 57 m and the drive takes 3 h 6 m, and Glenwood Hot Springs Pool is closer to the train station than Iron Mountain.

What we measured on 8 November 2026

We read Amtrak's California Zephyr timetable and routed the drive and the walks with street addresses placed on a map. Driving times assume no traffic.

• The train is 3 h 51 m slower than driving. It is the right choice only if you want to skip I-70 or ride the scenic route.
• The train arrives at 2:43 p.m. and the eastbound train leaves at 11:42 a.m. the next day, so you get 20 h 59 m in town. A train day trip is not possible, so book one night.
• From the station, the closest pool is Glenwood Hot Springs Pool at 0.26 miles. Iron Mountain is 0.66 miles farther, so plan a taxi or a 20-minute walk with your bags.

Our plan for a train trip, built from these times:

1. Day 1, 2:43 p.m.: Get off Train 5 and drop your bags at your hotel.

2. Day 1, evening: Walk 20 minutes to Iron Mountain, which stays open to 10 p.m. The Twilight Pass covers 8 to 10 p.m.

3. Day 2, morning: Soak at Glenwood Hot Springs Pool from 9 a.m., 6 minutes from the station, then catch Train 6 at 11:42 a.m.

So, by train, plan one night in town, and drop your bags before you walk to Iron Mountain.

How much does Iron Mountain Hot Springs cost in 2026?

Price: General Access (all ages, "family-friendly fun"): $43 to $75. All Access (21 and over, "adult-only relaxation"): $75 to $150. Both come as a Quick Dip, up to three hours, or a Day Pass with re-entry. The page gives ranges and does not say what decides the price

Price: Online reservations are $5 less than walk-in rates. You can cancel or change once for free up to 48 hours before your visit. Other changes cost $5 a pass, if there is space. Medical staff, military, seniors, students, government workers and teachers get 10 percent off after an ID.me check

Price: A Buy One, Get One Free online offer runs 2 to 20 November

Note: Each guest gets two free towels. Extra towels cost $5 each. RFID lockers are free with a reservation

The pass names changed in late October 2026. General Access was called Select Access, and All Access was called Premier Access, at the same price ranges. The site lists no child price and no senior base price.

So, an all-ages pass costs $43 to $75, a 21-and-over pass costs $75 to $150, and booking online saves $5.

What are the Iron Mountain Hot Springs hours?

Hours: Daily, 9 a.m. to 10 p.m. Closed on Thanksgiving Day 2026 and Christmas Day 2026. Early close at 5 p.m. on Christmas Eve 2026. For 2027 the page lists closures on 13 to 15 April and 19 to 20 October, plus Thanksgiving Day, an early close on Christmas Eve and Christmas Day

Note: Arrive 10 minutes early to check in. At check-in you sign the waiver, get a wristband and show a government photo ID

The home page and the first visit guide also post a banner when the site closes to the public at 4 p.m. for an annual member event. Check the home page on the day you go.

So, plan for 9 a.m. to 10 p.m., and check the site for a closure on your date.

Do you need reservations at Iron Mountain Hot Springs?

Booking: Reservations are not required, but tickets sell out, mostly on weekends, so the FAQ suggests booking ahead. Buying online saves $5 per person. A Quick Dip Pass gives up to three hours on the property, and a Day Pass lets you leave and come back all day. A Twilight Pass gives up to two hours between 8 and 10 p.m. at a lower price

Note: Outside food, drinks and alcohol are not allowed. There are two cafes on site. Smoking and vaping are not allowed anywhere. Remove jewelry before you soak, because the mineral water can tarnish it

So, book online for a weekend visit, and bring nothing to eat or drink.

What are the age rules at Iron Mountain Hot Springs?

Note: All Access is for guests 21 and over, and a valid ID is needed for it and for alcohol. Children under 5 cannot use the geothermal hot springs but can use the Family Zone, with the Family Mineral Pool and the Jetted Mineral Spa. Guests under 21 cannot enter the Sauna Summit, the WorldSprings pools and area, or the Sandbar Cafe

Note: Minors must have a waiver signed by a parent or legal guardian, at check-in. Waivers cannot be signed ahead of time

The FAQ also says guests under 18 may buy a soak pass, but a parent or legal guardian must sign the waiver in person at check-in, and children under 13 must be supervised by a parent or guardian at all times.

So, children under 5 stay in the Family Zone, and a parent must come to check-in for anyone under 18.

How many pools does Iron Mountain Hot Springs have?

Note: The home page says 35 pools, counting the new expansion. The water runs from 89 to 112 degrees F. The Sauna Summit expansion has five saunas and three plunge pools, and the expansion added two mineral pools, one with magnesium and one with potassium

In mid-October 2026 the home page gave the range as 89 to 108 degrees F. It now says 112. The Glenwood Springs tourism office FAQ still says 16 smaller geothermal pools and a chlorinated family pool, and that the site reopened in its current form in July 2015. That count is from before the expansion.

So, the hot springs' own site says 35 pools, and the older count of 16 leaves out the expansion.

Is Iron Mountain or Glenwood Hot Springs Pool better?

Both are in the same small town, 0.88 miles apart on foot. This table compares the two from their own pages and our walk times.

Daily, 9 a.m. to 10 p.m. Adult price $43 to $75 (General Access) or $75 to $150 (All Access, 21+). No child price listed. 35 pools at 89 to 112 degrees F. No lodging listed.

Price: Glenwood Hot Springs prices: day pool pass $42 to $60 for adults and teens, $30 to $38 for children, free for ages 2 and under. Prices vary between off-peak and peak times, and the page does not give the dates. Athletic Club day pass $69 to $77

Note: Glenwood Hot Springs pools: the Grand Pool, which it calls the world's largest hot springs pool, is over two city blocks long. The Therapy Pool is 104 degrees F. The Yampah Mineral Baths are five pools and become adults only after 5 p.m.

Note: Glenwood Hot Springs closures: the pools close on Tuesday 17 November 2026 for maintenance. The Sopris Splash Zone and Shoshone Chutes are closed for the season until March 2027

The tourism office FAQ says the Glenwood pool opened on 4 July 1888. Our verdict: pick Glenwood Hot Springs Pool if you arrive by train, want one big pool, or want a hotel on the same site. Pick Iron Mountain for many smaller pools, a 21-and-over pass or a soak until 10 p.m.

So, adult prices start at about the same $42 to $43, and the choice comes down to one big pool or many small ones.

How do you get to Iron Mountain Hot Springs without a car?

Getting there: Amtrak California Zephyr: Glenwood Springs station (GSC), 413 7th Street, a station building with a waiting room. Train 5 leaves Denver Union Station at 8:46 a.m. and reaches Glenwood Springs at 2:43 p.m. Train 6 leaves Glenwood Springs at 11:42 a.m. and reaches Denver at 6:59 p.m. Both run daily (Amtrak California Zephyr timetable, printed 5 Nov 2026)

Note: Amtrak lists the California Zephyr at 51 percent on time for 2024, against an 80 percent standard

Getting there: Bustang: the tourism office says to take the A-Line train from Denver International Airport to Union Station, then Bustang's West Line or Amtrak to Glenwood Springs. Bustang stops at the West Glenwood Park and Ride, 2307 Wulfsohn Road. Bustang's own site has the current times and fares

Getting there: Local buses: Ride Glenwood Springs city buses are free and run daily every 30 minutes, year-round. The tourism office gives the hours as 6:53 a.m. to 7:53 p.m. and a usual RFTA fare of $7 from Glenwood Springs to Aspen

Getting there: By road: Glenwood Springs is 160 miles west of Denver on I-70, at exit 116 for downtown and exit 114 for West Glenwood. We routed it at 157 miles and 3 h 6 m from Denver Union Station with no traffic. Denver International Airport is about 180 miles east. Iron Mountain's own page says the town is about three hours west of Denver. Winter weather on I-70 adds time

The 3 things to plan before you go car-free:

• The Ride Glenwood fall route map names no stop at Iron Mountain, so plan to walk or take a taxi for the last stretch.

• The walk from the Amtrak station is 0.92 miles, about 20 minutes, to Iron Mountain, and 0.26 miles, about 6 minutes, to Glenwood Hot Springs Pool.

• Bustang's times and fares are on its own site, and the stop is at West Glenwood, not downtown.

So, the train gets you from Denver to Glenwood Springs by 2:43 p.m., and Iron Mountain is a 20-minute walk from the station.
