About Spiers Springs

Spiers Springs offers a quietly soothing experience with its warm waters gently flowing at 79°F. Nestled in a rugged California canyon near Putah Creek, this primitive warm spring invites you to connect deeply with nature through its authentic, unrefined charm. The twin springs create a serene setting that feels untouched and timeless.

Getting There

Reaching Spiers Springs requires a bit of adventure, as it sits off the beaten path in a canyon. You’ll likely need a sturdy vehicle to approach the trailhead and prepare for a moderate hike through natural terrain. Parking is limited near the access point, so plan accordingly and wear sturdy footwear for the trail.

What to Expect

You’ll find two small pools formed by clear, warm water flowing about 7 to 8 gallons per minute. The spring maintains a steady 79°F temperature, ideal for gentle soaking without heat overload. Expect a peaceful, rustic atmosphere with no developed facilities—immerse yourself in the sounds of the creek and canyon surroundings while enjoying this calm, intimate spot.

Tips for Visitors

Visit during weekdays or early mornings to avoid any occasional visitors seeking solitude here. Bring everything you need—water, snacks, and sun protection—as there are no amenities. Respect the natural environment by packing out all trash and minimizing impact, ensuring Spiers Springs remains a pristine part of California’s swimming holes.
