Radium Hot Springs, Radium, CO



Radium Springs is a single warm pool, temperature around 90 degrees, that is on the banks of the Colorado river just a few miles south of the town of Radium. This spring sits at the base of a 60 foot cliff that thrill seekers often jump off of into the Colorado river. Then you’ll swim right over to the 20 foot diameter hot pool and warm up. Easiest access is to actually float down the Colorado on a raft or kayak to access it that way. It’s a 20 minute walk on foot and an even more dangerous and gnarly drive in a 4 by 4. The water here is pretty fantastic and someone years ago piled rocks in the form of an oval to create a large natural hot tub right on the river.

  1. We love this hot spring but it’s not hot, I would definitely say it’s a warm spring; my sister wouldn’t soak (winter time) because water is too cold for her.

  3. I was just out to the hot spring this past weekend and there is a permanent closure of the 4×4 trail .2 miles from location that Google maps will direct you to, so there is a mandatory hike in approximately .5 miles, bushwhacking down the hill side is not recommended, just continue on the trail to the first right turn and make another right when you reach the cliff on the riverside. Still a shorter hike than the hike in from the State bridge side.
