Snell Valley is a depression landform in Napa County, California. This feature is located approximately five miles north of Aetna Springs. The valley is noted for its diversity of wildflowers, and within Snell Valley is the Missimer Wildflower Preserve. An example of wildflowers in Snell Valley is Gold Nuggets, Calochortus luteus.
Snell Valley was part of Rancho Guenoc when it was deeded as part of a Mexican land grant in 1845. It is assumed that the valley is named after George and Hiram Snell, two brothers from Germany, who were documented as residents of the Guenoc Rancho in 1857.
