Portola Valley, California

Surrounded by wooded hills, this pristine and picturesque town of 4500 residents is located in San Mateo County, in a green and gold valley astride the world-famous San Andreas Fault. An extensive trail system, scenic roads, open space and natural views contribute to one's feeling of being in the country, as do architectural guidelines that stress "blending in". Commercial activity is encouraged to the extent that it primarily meets needs of residents of the community. These factors have enabled the town to retain a rural ambiance reminiscent of earlier days.
