Sam McDonald, a unique and interesting 850-acre facility, is located approximately 3 miles west of La Honda on Pescadero Road. The park actually represents contrast between two separate natural environments. The northwesternly half, near 400 acres between Pescadero Road and Highway 84, is principally a lush growth redwood forest. The 450-acre portion, southeasterly , is primarily open ridge, grassy knolls and patchy brush areas. From this ridge area, vistas of the Butano and Skyline Ridges, and the Pacific Ocean can be seen.
