Mono Hot Springs - Hot Springs in California

Like a department store of wild hot springs.

Many remnants of bathhouses from the Great Depression era also remain.

Crossing the Log Bridge

The road through the Sierra Nevada Mountains seems to climb all the way to the heavens.

Dirt Road 01

It's a two-and-a-half-hour drive from the nearest major city, Fresno.

Green Bridge 02

While mostly paved, the road conditions are, as you can see, quite challenging.

F.S. Campground 01

Just north of the green bridge crossing the South Fork San Joaquin River lies the Forest Service campground.

F.S. Campground 02

This campground is operated by the different entity than the adjacent Mono Hot Springs Resort.

South Fork San Joaquin River 02

The campground is open only from June to September.

This is a somewhat primitive campground with vault toilets, but online reservations are available.

Old Pedro 02

Scattered throughout the wide area south of the South Fork San Joaquin River, accessible by crossing a log bridge from this campground, are wild hot springs.

Water Temp 02

Just across the river on a small hill stands the tubs known as Old Pedro.

The slightly cloudy water was at a perfect temperature of 104 degrees.

Reed Pools 02

Among the wild hot springs, they were the most well-maintained and cleanest tubs.

Reed Pools 01

The Big Creek Project, a large-scale hydroelectric power initiative launched in 1910, made the region accessible by automobile by 1927.

The beautiful scenery and hot springs began attracting large numbers of visitors from across the state.

In 1934, development began by the Civilian Conservation Corps as part of the New Deal's unemployment relief efforts.

Tub 01

Before World War II, Japanese Americans reportedly stayed here throughout the summer because the water resembled that of their homeland's hot springs.

Empty 01

The bathhouse was demolished in 1963, and since then the southern area of the South Fork San Joaquin River has been left as wild hot springs.

The numerous structures left behind in the grassy fields are relics of the Great Depression era.

Rock Pool 01

The sign that reads Deep Spring.

Deep Spring 01

Some hot springs naturally bubble up from the ground, while others feature the remains of old bathhouses, creating a rich variety.

As I continued further upstream, the hills became increasingly rocky.

Rocky Mountain 01

Between the rocks, several small hot springs intermittently spew gases.

Iodine Springs 01

My favorite spot was this pool nestled between the giant boulders.

Old Mud Baths 05

From the deepest part, gas was gushing out like a natural jacuzzi, and the smell of sulfur was noticeable.

At this point, you've walked back to the green bridge you saw first.

Soaking 01

You could have used the boulder as a parking spot and set out on a wild hot spring tour without passing through the campground.
