About these waters
Hidden in a canyon of the Colorado River between Kremmling and State Bridge, Radium's sandy-bottom pool sits against a sheer cliff and is reached by scrambling down a fifty-foot rock chimney or by rafting in. The free, undeveloped pool sits on BLM recreation land with no facilities at all. Go in summer or fall; spring snowmelt can flood it completely.

Good to know
- Listing researched October 2026 — prices and hours change, always confirm with the spring before visiting.
- Hydrate between soaks and limit hot soaks to 15–20 minutes — mineral water dehydrates fast.
- Wild springs run on the honor system: pack out everything, leave the pool cleaner than you found it.

Radium Hot Springs: FAQs
Do I need a reservation or permit to visit Radium Hot Springs?
No reservations — wild springs are first-come, first-served. Some trailheads require a parking pass or day-use fee, so check the listing details and current land-manager rules before you go.
What should I bring to Radium Hot Springs?
Swimwear and a towel, drinking water, a trash bag (pack out everything, including food scraps), and a headlamp if you're staying for sunset. Never bring glass near a wild spring — broken glass in a pool ruins it for everyone.
Is the water temperature reliable at Radium Hot Springs?
Wild spring temperatures shift with seasons, rainfall, and river levels — a pool that's perfect in October can be scalding or flooded in May. Test the water with a hand before getting in, and check recent trip reports for current conditions.
