Willett Hot Springs Information Near Santa Barbara
Tucked into the hills of Los Padres National Forest is Willett Hot Springs, one fabricated tub where hot mineral waters are piped for the pleasure of visiting hikers. The springs are approximately 50 miles east of Santa Barbara and 21 miles north of Ojai, California. This hot springs tub averages 100°F.
You’ll drive on a forest road to the Piedra Blanca trailhead to hike this somewhat well-visited trail. Willett is ideal for a fall, spring, or winter visit when the weather is mild. People may also enjoy camping in one of the many free campsites and swimming in Sespe Creek. There are also other naturally-occurring hot spots where water streams into the creek from the earth.
Seasonal Access Information
Due to the exposed wilderness, the best season to visit Willett Hot Springs is in the spring and early summer. Fall is also good, though it will be the driest season and riskiest for wildfires. Winter may be rainy, and summer is quite hot. Always check the daily forecast before hiking to the hot springs.
The optimal time to visit Willett Hot Springs is between March and early June in the spring. Wildflowers are blooming and the grass is greener. Expect higher water crossings and flash flood risks depending on the rains. Spring and early summer are nearly perfect for soaking in the hot springs.
Fall is also a good time to visit Willett Hot Springs, ideally between mid-October and early December, when the daytime temperatures still go up to 70°F. These months are the driest, so watch for wildfire notices on Inciweb. However, there won’t be any challenging water crossings.
If the summer or winter is the only season to hike to Willett Hot Springs, plan your route, bring a satellite communication device, and tell others about your plan.
There are several excellent camping options for visitors to Willett Hot Springs. Additionally, all camping is free in the Sespe Wilderness.
As you hike from the Piedra Blanca trailhead to the hot springs, you’ll encounter three wilderness campsites: Bear Creek, Oak Flat, and Willett. All camps are first-come, first-serve. The Willett campground is conveniently located close to the hot springs, making it a popular weekend backpacking trip for local Californians.
About five miles down the trail, the midway point is the Bear Creek campsite, which has swimming holes and shaded campsites. Oak Flat is the second campsite at the seven-mile mark. Oak Flat has a swimming hole and tree-covered grounds. Finally, you’ll reach Willett at the ten-mile spot. Here, you can enjoy the natural hot springs.
As this is the wilderness, you’ll need to get a fire permit to use your camp stove, and you won’t be permitted to light a campfire during the hottest, driest months. Additionally, it’s essential to bring a water filter and know how to poop in the wilderness and take out your trash.
