San Geronimo Creek (a.k.a. Paper Mill Creek), one of the few remaining spawning grounds for Coho salmon (Oncorhynchus kisutch), runs through both towns. Lagunitas Creek, a tributary to San Geronimo Creek, is home to the largest remaining wild run of Coho salmon in Central California. These Coho are part of the Central California Coast Evolutionarily Significant Unit (CCC ESU), and are listed as "endangered" at both the state and federal level.

The towns line the western end of the San Geronimo Valley, extending into the forested south ridges and slightly into the grassier northern ones.
