Iron Mountain Hot Springs
Resort · Glenwood Springs
Iron Mountain Hot Springs is a large riverside soaking complex in Glenwood Springs, set on the Colorado River. It is built around 35 pools, and the property is split into family areas and adults-only areas, so you pick the kind of visit you want.
The all-ages side holds 16 geothermal hot springs fed by natural springs, with water the site gives as 98 to 108°F, plus a cold plunge. The Family Zone has a large mineral pool, a jetted mineral spa and a water sluice, and children under 5 must stay there rather than use the hot springs. The 21-and-over side adds 12 WorldSprings pools, which use fresh water with minerals added to imitate famous springs like the Blue Lagoon and the Dead Sea, along with the Sauna Summit, which has five saunas and magnesium, potassium and cold plunges.
Admission is sold as two passes: General Access for all ages, and All Access for adults 21 and over. Prices range from $43 to $75 for General Access and $75 to $150 for All Access, and booking online is $5 cheaper than walking up. Two towels and a locker are included. Two cafés serve food and drinks, and outside food, alcohol and coolers are not allowed. Dogs are not allowed except service animals.
The property is open daily from 9 a.m. to 10 p.m. Everyone signs a waiver in person at check-in, and a parent or guardian must sign for anyone under 18.

Before you go
Best time to visit: The pools are open all year and reviewers praise the river and mountain views by day and the lit pools at night. Weekdays and early mornings are calmer, and reviewers say weekends and holidays are the busiest, with some days sold out. The adults-only side is a quieter option when the main pools are full.
- Book ahead for weekends and holidays. The site says tickets sell out on busy days, and booking online saves $5 per person.
- Go on a weekday or early in the day. Reviewers describe weekends and holidays as crowded.
- Choose the pass that fits your group. General Access is for all ages. The All Access pass is for adults 21 and over and adds the WorldSprings pools and Sauna Summit, which reviewers often call quieter and well worth it.
