Franklin Hot Springs is a natural geothermal site in the foothill country of Fresno County east of Sanger, California. The spring produces water at around 38°C in rolling oak-grassland terrain near the Kings River drainage. The foothills between Fresno and Yosemite harbor numerous geothermal seeps, and Franklin is among the more accessible of these lesser-known warm springs.
