The sulfur smell hit first, then the steam, then ten miles of trail finally made sense. I’m Vanessa, founder of CATRAVELTIMES, and I’ve spent years chasing down Hot springs California worth the drive, the hike, or both.

Willett Hot Springs sits 10 miles deep in the Sespe Wilderness, north of Ojai, California a man-made tub fed by a natural geothermal source, tucked at the end of one of the toughest hikes I’ve done for a soak. It’s free to visit, it’s open as of this year, and it’s one of the best backpacking hot springs in the state, provided you’re willing to earn it one mile at a time.

What is Willett Hot Springs?

Willett Hot Springs sits on Chumash land, soaked in long before it had a trail marker. The current 10-foot tub is man-made, piped from a geothermal source, holding at 99–102°F. Entry is free, the rating sits at 4.8/5, and spring and fall are the best months to visit.

Climbing the final switchbacks to that sulfur-scented pool, I understood why backpackers treat this place like a pilgrimage the kind of place that keeps me building CATRAVELTIMES one trail at a time. Now let me tell you how to actually get there, because the drive and the hike are their own story.

How Do Find Willett Hot Springs?

The Piedra Blanca Trailhead, off Highway 33 about 20 miles north of Ojai, California 93023, is the exact starting point for Willett Hot Springs. Ten miles of trail separate the parking lot from the tub, all of it following Sespe Creek east.

The drive to the trailhead is paved the entire waythe road stops being the easy part the moment you shoulder your pack. I lost the trail once near the second creek crossing; it picks up again on the opposite bank, easy to miss if you’re not watching for it. And the moment I dropped my pack at Willett Camp, I understood why I had to stop and take photos before I even changed into my swimsuit.

I photographed the creek crossings at golden hour, the grassland stretch that looks almost southwestern, and the tub itself steaming against the canyon walls at dawn. Every shot tells a different part of the walk in.

Everything You Need to Know About Willett Hot Springs

Is Willett Hot Springs Closed?

Willett Hot Springs is open as of 2026. Highway 33 has faced intermittent closures north of Rose Valley in past years due to storm damage, so I always check current Los Padres National Forest (LPNF) alerts before I drive up. The springs themselves haven’t closed

How Long Is the Willett Hot Springs Hike?

The hike from Piedra Blanca Trailhead to Willett Hot Springs runs about 10 miles one way, with roughly 900 feet of elevation gain. I’ve done it as an overnight backpacking trip both times a 20-mile round trip in a single day is possible, but I wouldn’t rush it just to save a night outdoors.

Is Willett Hot Springs Good for Backpacking?

Willett Hot Springs backpacking works well as a one-night trip, with three established camps along the way Bear Creek at mile 5, Oak Flat at mile 7, and Willett Camp right near the springs. I stayed at Willett Camp both times. It puts you close enough to soak at sunrise before anyone else shows up, and it’s easily one of the more rewarding overnight trips in our full hot springs destinations guide.

What’s the Willett Hot Springs Trail Like?

The trail follows Sespe Creek through chaparral and oak groves before opening into grassland that feels almost like a different state. The final half mile climbs 300 feet of switchbacks to reach the tub the steepest stretch of the whole route. I recommend the Sykes Hot Springs trail if you want a similar creek-and-canyon backpacking feel closer to Big Sur.

What’s the Water Temperature & Best Time to Visit Willett Hot Springs?

The water holds at 99–102°F, piped into a 10-foot man-made tub from the geothermal source above it. It’s warm enough to soak for an hour without watching the clock, and cool enough that summer afternoons make the hike in feel like the harder part.

Season	Why Visit	Best Time	Water Temperature
Summer	Long daylight hours for the hike, but exposed trail sections get hot	Early morning start	99–102°F
Winter	Fewer crowds, but Sespe Creek can flood and Highway 33 may close	Check LPNF alerts first	99–102°F
Spring	Wildflowers, flowing creek, mild temperatures	March–May	99–102°F
Fall	My favorite window — cool air, clear trail, low crowds	September–November	99–102°F
Year-Round	Tub stays warm regardless of season	Anytime conditions allow	99–102°F

I’d go back in October every time. The air has that cold edge that makes the tub feel even better. Once you know when to go, packing right matters just as much.

Things to Do at Willett Hot Springs?

I spent most of my time soaking at dawn before the day-hikers arrived, but the creek swimming holes along the way stole a few extra hours I hadn’t planned on. I wish I’d had one more day to sit at Oak Flat doing nothing.

Soak at the Main Tub

The 10-foot tub sits right at the trail’s end, rated 4.8/5 by visitors, free to use. It’s the whole reason for the hike, and it delivers.

Swim at Bear Creek Camp

Located 5 miles in, Bear Creek has shaded swimming holes and flat camping ground. It’s a solid rest stop or an easy first-night camp for a slower two-night trip.

Explore Oak Flat

Sitting at the 7-mile mark, Oak Flat has its own swimming hole and tree cover. I’ve used it as a lunch break both times I’ve hiked this trail.

Hike to Sespe Hot Springs

About 5–6 miles beyond Willett, Sespe Hot Springs offers a hotter, more remote soak for backpackers who want to extend the trip.

Visit Fort Tejon State Historic Park

Located off I-5 near Lebec, this historic site makes a good stop on the drive up or down, with a small entry fee and exhibits on California’s frontier military history.

Check Out Wind Wolves Preserve

A large conservation area near Bakersfield with hiking trails and wildlife viewing a good detour if you’re combining this trip with other Central Valley stops. Pair it with a visit to Miracle Hot Springs if you’re routing through Kern County.

Once the hiking’s done, you’ll want somewhere real to sleep and eat — here’s where I’ve stayed and refueled.

Backpackers call it one of the best wilderness hot springs in Southern California. Solo hikers, couples, and small groups all show up here, though families with young kids are rare given the mileage.

Final Thoughts

Willett Hot Springs isn’t a place you stumble into. You earn it 10 miles in, legs tired, dust on your boots. The tub is small, the water is warm, and the canyon around it doesn’t care that you made the trip.

I still remember the silence at dawn, steam rising off the water while the ridgeline turned orange. This is for backpackers who want a real destination, not a drive-up soak. If you’re not ready for the miles, skip it. If you are, I’ll see you on the trail.
