What Is Wild Willy’s Hot Spring?
Wild Willy’s hot spring is also known as Crowley hot springs. Along with Crab Cooker hot spring, Wild Willy’s is one of the most popular hot springs near Mammoth Lakes. Both consist of natural hot pools with stunning mountainous backdrops.
Unlike many of the other hot springs in the area, which are man made tubs fed by pipes originating at a geothermal source, Wild Willy’s is composed of natural hot spring pools.
The hot springs at Wild Willy’s are unique in the fact they are part of a tiered hot stream with multiple pools allowing several soakers to fit comfortably.
Is Wild Willy’s Hot Spring Clothing Optional?
Clothing is optional at Wild Willy’s hot spring. We encountered both nude and clothed bathers during our visit. So if nudity makes you uncomfortable, you may want to skip this one.

Why Visit Wild Willy’s Hot Springs?
You should definitely add Wild Willy’s to your California bucket list just for the gorgeous scenery alone. Even if you aren’t interested in soaking at the hot springs, this area is a photographers dream.
Most people visit Wild Willy’s as part of a longer California road trip, after hiking in Yosemite National Park or exploring Death Valley.
Can You Swim At Wild Willy’s Hot Springs?
Yes, you can swim at Wild Willy’s hot springs. Although the pools found here are only about two feet deep so consider your visit a soak rather than a swim.
Best Time To Visit Wild Willy’s Hot Springs
The best time to visit Wild Willy’s is at sunrise during late spring or early fall. This time of year has ideal weather conditions and early morning is the best chance of getting the hot springs all to yourself.
Best Season To Visit
While Wild Willy’s hot spring is open all year, the best time to visit this beautiful place is in the late spring or early fall. During these two seasons, the weather is perfect for soaking without being too hot or too cold.
If you visit during the summer, not only do you run the chance of sharing the hot springs with many other people, but the temperature may be too warm to fully enjoy a soak.
If you visit during the winter, the roads may be completely impassable.
While the highways around the hot springs are well maintained in winter, the dirt road (Benton Crossing Road) is not maintained in winter.
Be sure to check the weather conditions and make sure you have the appropriate vehicle if you plan to visit during the winter months.
Best Time Of Day To Visit
Sunrise is without a doubt the best time to visit Wild Willy’s hot springs while sunset will be the worst time to visit. Try to arrive just before sunrise so you can soak while you watch the sun peak over the mountains in the morning.
We would also recommend you try to visit midweek rather than the weekend. The crowds will be much smaller and make for a more enjoyable visit during the week.
Because Wild Willy’s hot springs is easily accessible, it can become extremely crowded. For the best experience, you want to visit when the crowds are minimal.

The Pools Of Wild Willy’s Hot Springs
One of the best parts about Wild Willy’s hot springs is plenty of room for many groups to enjoy the beautiful scenery. However, in order to reach the hot springs, there is a very short hike.
From the parking lot, there is an elevated boardwalk over the sagebrush plains which will take you straight to the hot springs. The boardwalk is about 0.2 miles long and is very well maintained.
As you walk down the boardwalk, be sure to take in the surrounding views. The snow capped mountains in the distance are breathtaking.
How Many Pools Does Wild Willy’s Have?
There are three main pools at Wild Willy’s hot springs. Two of the pools are located right after the boardwalk along a tiered hot stream.
The third and final pool is a bit more secluded in the distance if you prefer a more private setting.

The Large Pool
The large pool will be the first hot spring you come to after the boardwalk and is one of the most popular spots due to its big size.
At about ten feet wide and two feet deep, this pool can comfortably fit many people.
Because this is the closest pool to the tiered hot stream, this pool is most often the hottest. If there are too many people in this first pool, you have two other options.
In the photo above, the first pool is in the background. There was a group in this first pool when we visited.

The Second Pool
The second pool along the tiered hot stream system is much cooler and smaller compared to the first large pool. But it is a great spot if there are many bathers in the first pool.
You can easily submerge yourself in this pool and it comfortably fits two people. We loved this second pool and spent a bit of time here.

Additional Pool Nearby
If you sit in the first or second pool, you will notice a large pile of rocks in the distance. An additional pool is located here and will comfortably fit about two people.
This man-made pool is shaped like a heart and can be very hot so be sure to check the temperature of the water before you head in.
