Monrovia Canyon Park Spring, Monrovia, California

## Overview Monrovia Canyon Park Spring is a natural public drinking spring nestled within the scenic Monrovia Canyon Park in the San Gabriel Mountains foothills of Monrovia, California. The spring delivers a constant flow of cold water and is situated along the popular Ben Overturff Trail, a roughly 7-mile route that winds through oak woodland, chaparral, and riparian canyon habitat. The water has been reported to have a pH of 7.9 and a total dissolved solids reading of approximately 141 PPM, suggesting a clean, mildly alkaline mineral profile that visitors have described as refreshing. Monrovia Canyon Park itself is a 30-acre nature preserve managed by the City of Monrovia, cherished by hikers, trail runners, and nature lovers for its waterfalls, diverse wildlife, and shaded canyon trails. The park sits at the base of the San Gabriel Mountains, where seasonal streams and underground aquifers feed springs like this one as water percolates through the granitic and metamorphic rock formations characteristic of the range. Access to the spring is open to all visitors during park hours. ## Directions **From the park entrance at 1193 N Canyon Blvd, Monrovia, CA 91016:** 1.
