Immediately after hiking Mount McPherson (also known Mount Bielawski, the highest point in Santa Cruz County), I drove northwest on Skyline Boulevard for 15 minutes over to Long Ridge Road. Then I hiked up to the summit of the Long Ridge Open Space Preserve, which was the highest point in San Mateo County, Calfiornia. I did this to celebrate the Winter Solstice.
The elevation of Long Ridge high point is 2621 feet (799 m).
