Twelve-mile Hot Spring, alternatively known as 12 Mile or Bishop Creek Hot Spring, is a large and shallow hot pool flowing from the bottom of a canyon wall 12 miles outside of the town of Wells.
The 105-degree spring surfaces into a man-made concrete pool that measures about 40 feet long. The gravel bottom of the pool is only about 2 or 3 feet deep, but the movement of water is sufficient to keep algae from collecting on the surface of the water, though some does stick to the tub walls.
The temperature within the pool varies with proximity to the source, and it generally stays about 102 degrees. There is no real sulfur smell to the water. However, the pool is well-known and accessible, so don't be surprised to run into others using the pool. Swimsuits seem to be the norm here.
The road to the spring can be traveled by high-clearance four-wheel drive vehicles when Bishop Creek is at lower flow, though most cars will have to park somewhere along the dirt road, which can be extremely rough and muddy and often too rutted for standard passenger cars. Most will have to find an area to park and hike the rest of the way in, possibly up to 1.5 miles up the easily-followed road, depending on road conditions. The spring is about a quarter mile upriver from the stream crossing. The canyon that the springs lie in is also incredibly scenic and wild, an anomaly in the otherwise flat valley floor in this part of the northeastern Nevada basin.
There are no services or amenities of any kind near the springs.
