Half Moon Bay is a city on the Peninsula in the San FranciscoBay Area of California. The Half Moon Bay Coastside is a rural seaside community about 30 miles south of San Francisco, and only an hour's drive from virtually anywhere in the Bay Area.
Highway 92 is perfect if you are coming in from either 101 or 280.
If you are coming from San Francisco you can also take 280 to Highway 1 for a very scenic drive through Devil's Slide, which has beautiful, breathtaking cliffs that descend steeply into the ocean. (Unfortunately, this will be bypassed in late 2012 by a tunnel.)
Almost all of the beaches are on or off of Highway 1 (a.k.a the Pacific Coast Highway) (Note some addresses are given as CA Highway 1, the Cabrillo Highway or the PCH.)
