Outside the small picturesque farming town of Paradise Valley (the only services offered here are a tiny market and a bar) is a scalding hot spring bubbling into a round caldera-like formation that eventually flows into a round trough at a much more ideal bathing temperature.
Paradise Valley Hot Spring, sometimes referred to as Little Humboldt Hot Spring, lies beside a bend in the Little Humboldt River. Paradise Valley itself is a wide, arid valley with some farming adjacent to the river, though all that is visible are the trees that grow along the waterway.
It is possible to walk to the travertine formation where water boils up before falling down a narrow channel and into a pipe that drops into the trough. The round stone formation is an interesting feature, though the soak itself is definitely a worthwhile experience. Isolation ensures that few people make it out to this spot, but some past visitors have constructed a set of steps leading down to the trough along with a small bench and wooden walkway to the trough itself.
Water flows out of the pipe at around 105 degrees, and the temperature of the trough can be adjusted by moving the pipe into or out of the pool. The water has no smell, though there is a small amount of algae that has collected in the trough.
Accessing the parking area can be extremely rutted and muddy following wet weather, in which case parking along the road and walking the last bit to the springs may be a good choice.
The springs themselves sit on private property where access has been allowed; however, people hoping to camp out should seek out a spot in the BLM land that lies just outside of the spring area.
The nearest services are at the junction of Highways 95 and 290.
