## The two big hot springs in Glenwood

## A hot springs day without the drive (what Aspen Privé arranges)

A private car down the valley and back, passes arranged, robes and water in the car, lunch in Glenwood and a massage at the house when you return. [Hot Springs Escape](https://aspenprive.com/experiences/hot-springs-escape/) · [ask us](https://aspenprive.com/contact.html?service=hot-springs).

## Which suits your group

- **Families**: Glenwood Hot Springs: one huge pool, a children's area and no reservation needed.
- **Couples and a quieter soak**: Iron Mountain: smaller pools at a range of temperatures, the sauna area and cold plunges.
- **After skiing**: Either works as an evening, but the drive back up valley at night in winter is the part to plan: a driver means nobody has to.

## The wild springs, and what's new

- **Conundrum Hot Springs**: A backcountry spring 8.5 miles in from Castle Creek Road. Overnight camping needs a Forest Service permit on Recreation.gov, released in batches: February 15 (for April–July), June 15 (August–November) and October 15 (December–March), 8 a.m. Mountain; they go fast. The trailhead road usually isn't plowed until late May.
- **Penny Hot Springs**: A free, primitive riverside pool on the Crystal River south of Carbondale; day use only.
- **New at Iron Mountain**: The Meadow, an adults-only (21+) lounge area with food and drink service, opened July 3, 2026 for Premier Access guests.

- [A driver for the evening](https://aspenprive.com/contact.html?service=evening-driver) (From $210 per hour): A car and driver on call for dinner and the night out, so nobody hunts for a taxi at midnight.
