Quick Info
Location: Glenwood Springs, along the Colorado River. What makes it special: 16 smaller pools, freshwater geothermal, modern design, river views. Pool temps: 98-108°F. Reservations recommended.
Iron Mountain Hot Springs opened in 2015, offering Glenwood Springs a second hot springs option with a completely different character. Where Glenwood Hot Springs Pool is massive and historic, Iron Mountain is intimate and modern. Sixteen smaller pools cascade along the Colorado River, each maintained at different temperatures.
The design emphasizes the natural setting. Pools are built into the riverbank with views across the water to red rock cliffs. The facility maintains a quieter, more relaxed atmosphere - no water slides, no splashing crowds. It's designed for soaking and conversation, not swimming laps.
The mineral water here is different too. Iron Mountain uses freshwater geothermal springs rather than the sulfur-tinged water common elsewhere. The result is clean-feeling water that won't leave a lingering smell on your skin or swimsuit.
The Pools
16 soaking pools range from 98-108°F. Each has a slightly different view and feel. You can move around and try different temperatures - some people like the hotter pools, others prefer just-warm. Finding your perfect spot is part of the experience.
The pools sit right on the Colorado River. In summer, you watch rafters float by. In winter, snow-covered banks and peaceful quiet. The contrast between hot water and cold air is even more dramatic when you can see the river flowing past.
One large jetted pool offers hydrotherapy for those wanting stronger water pressure on sore muscles. Popular after skiing or hiking.
The Vibe
Iron Mountain is calmer than the big pool. No water slides, no kids splashing wildly. It's designed for relaxation - quiet conversation, reading, or just zoning out watching the river. Families are welcome, but the atmosphere tends toward adults who want peace.
Poolside drink service is a nice touch. Local beer and wine available. Sip something warm while you soak - an amenity other springs lack.
Planning Your Visit
Reservations recommended, especially on weekends. Book online in advance. They use time slots - typically 2-hour sessions - to manage capacity and keep crowds down.
Sunset slots are popular in winter. The light over the river is beautiful and transitions to stars as you soak. Morning slots are usually less crowded if you prefer space.
Two in One Trip
Many visitors do both Glenwood hot springs in one trip. Hit Iron Mountain for relaxation - the intimate pools, river views, quiet atmosphere. Then do Glenwood for activity - swimming laps, water slides, the scale of the historic pool. Different experiences, same town.
