The experience

A place worth getting to know.

Radium Warm Springs is a small primitive pool on the banks of the Colorado River just upstream of Gore Canyon, about 15 miles southwest of Kremmling. River rocks wall off a warm pocket — typically 85–95°F — from the cold current. Access rules have shifted: the old Mugrage/CPW social trail is closed for wildlife habitat protection, so hikers now use the Warm Springs Trail from the Warm Springs Road parking area off Trough Road.

Plan your visit

This is a primitive site rather than a staffed resort. Check land access, trail or road conditions, and seasonal water levels before setting out; carry out everything you bring.

The old access via the Mugrage site is closed — the route is less obvious than old guidebooks say

The honest take

What to love. What to consider.

The highlights

  • Free riverside soak with canyon scenery on the Colorado Headwaters Scenic Byway
  • Short hike (about 0.75 mile) from the parking area — no backpacking required
  • Popular stop for rafters floating the Colorado River; a 45-foot cliff jump is nearby

Keep in mind

  • The old access via the Mugrage site is closed — the route is less obvious than old guidebooks say
  • The pool washes out during high spring runoff and runs lukewarm (85–95°F), not truly hot
  • Steep, unsheltered scramble down rocks to the river; no shade, no changing area, no facilities

Plan your visit

Make the most of your visit.

  1. Check the Recreation.gov Radium Recreation Area alerts before you go — trail closures and access rules have changed

  2. From Trough Road, drive about 1.5 miles northeast of Radium Road to Warm Springs Road and use the designated Warm Springs Trail

  3. Go in late summer or fall when the Colorado River is low so the pool actually forms

Your questions

Before you head out.

Is Radium Hot Springs still open?

The springs are open, but access changed: the CPW Mugrage site and its social trail that used to reach them are closed for habitat protection. The BLM now points visitors to the Warm Springs Trail from the Warm Springs Road parking area.

Is there a fee?

No — the warm springs are free to soak, with no reservations and no designated facilities.

How hot is the water?

Lukewarm — typically 85–95°F. It is a bath-temperature riverside pool, not a steaming hot spring.
