Big Caliente Hot Springs

## Overview Big Caliente Hot Springs is a popular natural hot spring located in the Los Padres National Forest in Santa Barbara County, California. Situated at an elevation of roughly 1,800 feet in the rugged backcountry north of Santa Barbara, this free-access geothermal spring has long been a favorite destination for hikers, backpackers, and hot spring enthusiasts seeking a soak in a scenic wilderness setting. The spring feeds a concrete-and-stone soaking pool that was constructed decades ago to capture the naturally heated water. Water temperatures at the source have been reported to reach approximately 115°F (46°C), though the temperature in the soaking pool can vary depending on flow rates and ambient conditions — typically settling in the range of 100–110°F. The hot water is believed to originate from deep geothermal activity along fault lines in the Transverse Ranges, a geologically active region where tectonic forces push heated groundwater to the surface. The water has a slight sulfur smell characteristic of many geothermal springs in the area. Historically, the hot springs of the Santa Ynez Mountains and surrounding backcountry were known and used by the Chumash people long before European settlement. Big Caliente, along with nearby Little Caliente Hot Springs, sits within a landscape rich in indigenous heritage. The name "Caliente" is Spanish for "hot," reflecting the region's Spanish colonial history. A U.S. Forest Service Adventure Pass or America the Beautiful Pass is generally required for parking at trailheads in the Los Padres National Forest. ## Directions 1. From Santa Barbara, head north on Highway 154 (San Marcos Pass Road) toward the San Marcos Pass. 2. Turn right onto East Camino Cielo Road and follow it east. The road is paved initially but becomes a narrow, winding mountain road. 3. Continue on East Camino Cielo until it transitions into Juncal Road (Forest Road 5N15) — also sometimes referred to as the Juncal Camp Road. 4. Follow the road downhill past Juncal Campground. The road becomes a rough, unpaved forest road (high-clearance vehicle recommended, especially in wet conditions). 5. Continue along the road to the Big Caliente trailhead and parking area. The hot springs are a short walk from the parking area — approximately 0.1 to 0.25 miles. 6. GPS coordinates: **34.5390, -119.5646**. A GPS device or offline maps are highly recommended, as cell service is limited to nonexistent in this area. *Note: Road conditions can change significantly with weather and seasonal closures. Check with the Los Padres National Forest – Santa Barbara Ranger District for current road and access conditions before heading out.* ## What to Expect Big Caliente Hot Springs offers a rustic, backcountry soaking experience. The main pool is a roughly 6-by-10-foot concrete-and-rock basin nestled among oaks and chaparral along a seasonal creek. The pool can comfortably fit several people at a time, though it can get crowded on weekends and holidays. The surrounding landscape is classic Southern California backcountry — rolling hills covered in chaparral, scattered live oaks, and dramatic mountain views. The area is particularly beautiful in spring when wildflowers bloom, and in autumn when the oaks turn golden. Visitors should be aware that the hot spring is clothing-optional by local custom. The site has no developed facilities — there are no restrooms, trash cans, or potable water at the spring itself, so plan to pack out everything you bring in. Nearby Juncal Campground offers basic camping facilities for those looking to extend their trip. The access road can be rough and may be impassable after heavy rains or during winter storms. Flash flooding is a concern in the narrow canyons of this region, particularly during and after rainstorms. Summer temperatures in the backcountry can be extreme, so bring plenty of water for the drive and hike. Poison oak is common in the surrounding vegetation — stay on established paths. While the hot spring water has historically been used for soaking, it is not recommended for drinking without proper treatment. The geothermal water may contain minerals and microorganisms, including the potential for Naegleria fowleri in warm freshwater — avoid submerging your head.
