Backcountry & natural soaks

For the adventurous, Colorado has free, primitive springs you earn on foot: Conundrum Hot Springs (a stunning 8.5-mile hike near Aspen, permit required), plus roadside-ish soaks like Radium, Penny, and Rainbow Hot Springs. These are undeveloped — some are clothing-optional, none have services, and you must pack out everything. Always check current access before you go.

Tips for visiting Colorado hot springs

Go in winter if you can — a snowy soak is unforgettable. Book ahead: Strawberry Park, Iron Mountain, and the resort pools often sell timed tickets, especially on weekends. Hydrate (you’re at altitude and losing water fast), limit soaks to 15–20 minutes at a time, and don’t soak and drink. For backcountry springs, know before you go and leave no trace.
