Unlike the more popular hot springs around Mammoth Lakes, Siphon Hot Springs attracts fewer visitors, giving you the opportunity to unwind without large crowds.

The Origin of “Little Hot Creek” Hot Springs

You might hear this spring referred to as Little Hot Creek, and for good reason.
A small creek runs nearby, connected to the larger Hot Creek, a well-known geothermal area.
On particularly hot days when the temperature of the main pool is too high for a comfortable soak, some visitors choose to relax in the cooler waters of the creek.
The creek also serves as an alternative soaking spot if the spring itself is too crowded.
So, whether youโre looking for a hot soak or a refreshing dip, the area provides multiple options for relaxation.
Pool Description and Surroundings
The main pool at Siphon Hot Springs is just a short 100-foot walk from the parking area, making it incredibly accessible for anyone who doesnโt want to hike far.
The pool itself is relatively small but perfectly sized for a cozy soak with about 8-10 people.
It’s constructed from natural rock and cement and features a control valve that allows you to adjust the water flow, making it one of the few natural hot springs with this added convenience.
If the water gets too hot, you can simply turn the valve to let less source water in or close it to let the pool cool down a little.
This unique feature adds to the comfort and flexibility of your soaking experience.

The surrounding area is peaceful and quiet, with panoramic views of the Sierra Nevada Mountains providing a breathtaking backdrop.
You can expect a tranquil atmosphere with little to no interruptions, as the more secluded location ensures fewer visitors compared to other hot springs in the region.
Water Temperature at Siphon Hot Springs
The water temperature in Siphon Hot Springs can vary but typically stays around 100-105ยฐF (37-40ยฐC).
The temperature can fluctuate due to natural geothermal activity, so it’s a good idea to test the water with your hand or foot before fully entering.

How to Get to Siphon Hot Springs
Getting to Siphon Hot Springs is relatively straightforward, though it involves a bit of off-road driving.
Hereโs a step-by-step guide to help you find your way.
- Starting Point: Mammoth Lakes
From Mammoth Lakes, take U.S. Highway 395 south. Youโll drive for about 5.5 miles until you reach Benton Crossing Road. Youโll know youโre on the right path when you pass the famous little green church, a local landmark. Turn left onto Benton Crossing Road - Drive for about 1.2 miles, take a slight left onto Whitemore Tubs Road
- Drive for about 3.3 miles, then turn left onto Owens River Road
- Drive for about 1.8 miles, take a sharp left onto Forest Road 3S138. This road is rough and can be rougher if it’s wet, so make sure your vehicle can handle the terrain.

From there, itโs just a short walk to the hot springs, but the trail can be rocky and uneven. Make sure to wear sturdy shoes and be prepared for some minor elevation changes if disperse camping.
