Hot Springs Pools at Wild Willy's
When you arrive, you will find two soaking pools on the site. Wild Willy’s Hot Springs pools do not have any hot water pipes. The thermal water comes directly from the ground, bubbling up into the pools. They are about 3 feet deep, have a gravel bottom, and a faint sulfur smell. You will find that the surrounding soil around the soaking pools is slippery, so pay attention and if possible, wear water shoes.
As you approach, you will find to the left, a small heart-shaped pool that can accommodate 4 to 5 people. With a temperature of around 105°F, this pool is hotter than the larger one. The larger pool at the end of the boardwalk has a lower temperature of about 96°F and it can accommodate about 15 people at a time.
Volunteers and visitors maintain the tubs, which are free to use. Please do not leave any trace of your visit. Leave the area better than you found it because this is the only way to preserve this treasure and keep it available for future use.
Before you go
It is important to note that:
- This is a communal pool site with a clothing-optional (unwritten) rule, and there may be nudity.
- The site is popular due to its beautiful setting and ease of access. Crowds are to be expected especially on weekends and holidays.
- During high use periods, the water may become polluted by human or organic matter.
- Do not splash in the pools. Keep your head out of the water to avoid infection.
- This is a desert location with no on-site amenities so bring towels and drinking water to rehydrate after soaking. Bring enough water if possible to clean up after soaking.
- Bring warm clothes and shoes in the winter because you will have to walk a distance to and from the hot springs to your car.
- No changing areas at the site. Change in the car before walking down.
- In the summer, be prepared for bugs.
- If visiting with kids, make sure to check the water before they go in.
- There may be algae in the water. Take note of the size of algal growth. A soaking pool with a lot of algae provides a favorable environment for bacterial growth.
When you get there
- Use the boardwalk from the entrance to the hot springs. The boardwalk was put there for a reason which is to protect the sensitive meadow habitat from high foot traffic.
- You may find cows freely grazing in the area or near the pools.
- You may meet a crowd or have the pools all to yourself.
How do you get to Wild Willy’s Hot Springs?
Wild Willy’s Hot Springs is located about 20-minute away from Mammoth Lakes, off US Highway 395. Depending on where you are coming from, there are several ways to get to this highway.
If coming from Mammoth Lakes take the U.S. HWY 395 South, or from Bishop, follow U.S. HWY 395 North until you reach Benton Crossing Road. You will know this when you see the green church. Take a right turn to follow the road and travel for about 3 miles until you reach a yellow crossing sign (or second guard) for cattle. After passing through this guard, turn sharp right and continue on the dirt road till you reach a fork in the road. Keep left and drive to a spacious parking lot which serves as the trailhead to the hot springs.
When you get to the parking lot which is free, you will find a wooden path or boardwalk laid out for about ¾ of a mile to the soaking pools. The terrain is flat and the trek which will only take about 7 minutes is easy. This little trek from the parking lot gives you the opportunity to take in the beauty of the landscape as you approach the soaking pools.
Any vehicle can make this trip but nothing beats a 4WD when you are travelling on a dirt or gravel road. So if you have the option to choose, go with a 4WD. If you decide to go on the trip with a smaller vehicle, you must drive slowly when you get to the graded portion of the road.
How do you get to Wild Willy’s Hot Springs in winter?
The drive during winter is basically the same except for the last stretch of the road. Pay attention while driving in winter because it is easy to miss the turn after the second cattle guard as everywhere is covered in snow. Once you take that turn, look ahead, and you will see steam rising from the hot tubs in the distance.
The cattle gate that leads to the dirt road and the parking lot is usually closed in winter when there is too much snow. You must park your car by the road and hike through the snow to the hot springs. This trek will take you about 30 minutes so you must be prepared especially for the trek back to the car.
There is no cold plunge by the hot spring pools. This means that when you emerge from the hot soaking tubs, you will be immediately exposed to very low temperatures. The sudden change can be shocking especially when you have to hike back to the car. This is why picking the appropriate clothes and shoes is essential.
Is there camping at Wild Willy’s Hot Springs?
Free camping is permitted at Wild Willy’s Hot Springs because it is situated on the Bureau of Land Management (BLM) land. However, it is important to know that camping is not allowed in the immediate vicinity of the hot springs. You can camp in the parking lot or the surrounding meadow. Also, note that campfires are not permited because the area is classified as sensitive habitat,
Remember that this hot springs site is primitive with no on-site facilities. Ensure to come with all you need and endeavour to pack out any trash before you leave.

3. Shepherd Hot Springs, Mammoth Lakes
In the center of a beautiful valley, with the Sierra Nevada mountain range serving as a backdrop, is a man-made, concrete soaking pool known as Shepherd Hot Springs.
The source of this mineral-rich water in the concrete soaking pool is a volcanic hot spring bubbling from the ground about 150 feet away. The thermal water is then piped to the soaking pool. At the source, the water temperature is about 136°F but it cools down to about 108°F as it flows through the pipe into the soaking pool. The temperature of the pool can be further adjusted using the valve on the pipe supplying the tub. This valve controls the amount of hot water flowing into the pool.
There is just one small soaking tub on the site which is about 2.5 feet deep and can only fit 4 people at a time.
Before you go
You should note that:
- This site is clothing optional which means you may encounter people soaking in their birthday suits. There is no privacy here unless you are lucky enough to have the tub all to yourself when you arrive.
- It is a low-flow soaking pool. This simply means that during high use, or when mother nature decides to reduce the amount of water seeping out from the geothermal source per minute, the pool may become dirty and possibly contaminated. In this case, use caution.
- Hot pools like this have been known to harbour fatal microorganisms. Keep your head out of the water as a precaution.
- If you take this trip during winter, the road leading to the hot springs parking lot might be closed. In this case, you must park your car by the roadside and trek through the snow to the hot springs. Be prepared for this and dress in layers.
