Kosk Hot Springs

## Overview Kosk Hot Springs is a remote, naturally occurring hot spring located in the rugged volcanic landscape of northern California, near the border of Shasta and Siskiyou counties. Situated at approximately 41.037°N, 121.933°W, the springs emerge in a wild, backcountry setting characteristic of the geothermally active Cascade Range region. The area's volcanic geology — shaped by millennia of tectonic activity along the Pacific Ring of Fire — gives rise to numerous thermal features, and Kosk Hot Springs is one of the lesser-known gems among them. The name "Kosk" is believed to derive from local indigenous or early settler terminology associated with the surrounding Kosk Creek drainage. The springs have likely been known to Native American communities in the region long before European settlement, though detailed historical records specific to this site are limited. As a free, undeveloped hot spring, Kosk Hot Springs offers a raw, off-grid soaking experience for adventurous visitors willing to make the journey into this remote corner of California's backcountry. ## Directions 1. From the town of **Burney, CA**, head north on Highway 89. 2. Travel into the backcountry roads east of the McCloud River area, navigating toward the Kosk Creek drainage. The GPS coordinates **41.0368, -121.9331** should be entered into a reliable GPS device or offline mapping app, as cell service is extremely limited in this area. 3. Access likely involves unpaved forest roads managed by the U.S. Forest Service (Shasta-Trinity National Forest). A high-clearance vehicle is strongly recommended, and 4WD may be necessary depending on road conditions and season. 4. Be prepared for unsigned or minimally signed turnoffs. Carry a detailed forest service map (such as the Shasta-Trinity National Forest Motor Vehicle Use Map) in addition to GPS. *Note: These directions are approximate and based on the GPS coordinates provided. Road conditions and access can change seasonally. It is advisable to check with the local U.S. Forest Service ranger district before heading out.* ## What to Expect Kosk Hot Springs is an undeveloped, primitive hot spring in a remote wilderness setting. Visitors should expect: - **Thermal water** emerging naturally from the ground, typical of the geothermal features found throughout this volcanically active region. Water temperatures can vary seasonally and by specific vent, so test the water carefully before entering. - **No facilities** — there are no restrooms, changing areas, signage, or maintained paths at the site. This is a true backcountry experience. - **Rugged, natural surroundings** — the landscape features mixed conifer forests, volcanic rock formations, and the sounds of nearby creek drainage. Wildlife in the area may include deer, black bears, and various bird species. - **Seasonal access** — snow and mud can make forest roads impassable during winter and early spring (roughly November through May, depending on the year). Summer and early fall typically offer the best access window. - **Solitude** — due to its remote location, Kosk Hot Springs sees very few visitors. Those who make the trek are often rewarded with a peaceful, private soaking experience surrounded by pristine wilderness. As with all wild hot springs, the water has not been tested or treated for public use. Visitors have historically used such springs for soaking and relaxation, but water quality can fluctuate.
