About Philo

Philo is a crisp, cold spring located in Northern California, offering a refreshing escape among towering redwoods. Its clear, cool waters flow into the Navarro River, creating a serene spot that invites you to dip into nature’s quiet embrace. This primitive swimming hole stands out among hot springs in California for its invigorating chill and peaceful atmosphere.

Getting There

To reach Philo, drive southeast on Route 128 past Navarro until you see the Philo-Greenwood Road on the right, marked by an “Elk” sign. After crossing a rustic wooden bridge near Apple Farm, park at a small pullout area opposite Hendy Woods State Park. From here, a brief 5-minute walk takes you to the spring, making it an accessible yet secluded adventure.

What to Expect

The spring’s water is icy cold, perfect for cooling off on warm California days. The surrounding forest muffles sounds, adding to the feeling of solitude. Facilities are minimal—expect no amenities—so the spot remains pristine and quiet, with few visitors even in peak summer.

Tips for Visitors

Visit during the summer months for pleasant weather and manageable water temperatures. Parking is limited, so arrive early to secure a spot. Bring sturdy shoes for the short walk and pack out all belongings, as there are no trash services or restrooms nearby. This free natural swim spot rewards those who respect its wild charm.
