This warm spring, with water steady at 72°F, invites you to soak in a soothing, natural pool surrounded by untouched wilderness. Its primitive character means you can connect deeply with nature, away from commercialized hot springs in California.

Getting There

Reaching Boron Spring requires a bit of adventure, as it lies off beaten paths typical for California swimming holes. You’ll likely park at a nearby trailhead and hike in over uneven terrain. Prepare for a moderate trek through scenic but undeveloped surroundings that reward you with solitude.

The water here is comfortably warm without being hot, perfect for a relaxing soak under open skies. The area sees few visitors, so you can expect a serene atmosphere without facilities or crowds. This natural setting demands a leave-no-trace mindset to preserve its pristine state.

Tips for Visitors

Visit during weekdays or off-peak seasons for the quietest experience. Bring sturdy shoes and plenty of water, as amenities are non-existent. There are no entrance fees, but respect the delicate environment by packing out all trash and minimizing impact on the surroundings.
