9 loop trails with longer back country hiking possible
The reserve is located three miles north of Guerneville on Armstrong Woods Road. From Highway 101- coming North or South- take the River Road exit (in Santa Rosa). Go west on River Road until you reach Guerneville. At the second stop light make a right hand turn onto Armstrong Woods Road. This road will end in the park.
